IChat 3 AV and QT 7.0.2 performance issues...

Right, here goes another strange one..
Upon upgrading to QT 7.0.2 I noticed that Video conferences in iChat 3 AV tend to hog the CPU so much more that video and audio keeps delaying and generally speaking, doing anything else with the system seems next to impossible. This is on a 12'' iBook 1.25Ghz G4...I do clearly recall that I had no such issues with previous QT versions, even after upgrading to QT 7...(I'm obviously on 10.4, 10.4.2 to be exact). Any ideas on what may be causing this?
Another thing is that being on DSL, I would expect iChat to fully saturate at least my upload path (128kbps) ie. broadcasting should technically be close to 12k/sec since I've not limited the throughput in the prefs...now is it really normal to be sending only 3-4k/sec of video to other buddies who are on DLS, too can receive upto 1024 and I'm not u/ling nothing at all? Same happens with audio chats, shouldn't the codec be dynamic in a way that it adjusts it's quality to accomodate the extra available bandwidth? Cause by the looks of it (MenuMeters) it only seems to transmit 2-3k/sec of audio and you can imagine that quality-wise this is nowehere near Skype...

You're welcome, Dimitrios.
... could you imagine of ANY way that my Planet ADE4300 modem/router seems to block outgoing port 5190?
If you have tried the suggestions in my previous link, have not changed settings, have not changed ISPs, and have not changed hardware, your ISP may have made some "improvements" that are causing you problems.
If you have had iChat AV working previously, you might want to try any applicable trouble shooting suggestions in the How Can I get iChat working again? FAQ.
Otherwise, I am out of ideas. Perhaps someone else can offer others.

Multiple EventListeners, modulus and rotating cubes... performance issues.

Hi.
I've created a grid of 3D cubes using modulus, and the 3d cubes are were created from the Math and Flash Tutorial, if you are interested it is here http://www.flashandmath.com/advanced/menu3d/.
What I am trying to accomplish (and it works, just the performance is lousy). All the cubes in the grid are inactive until the mouse hovers over them, then they start to rotate, and once the mouse moves off them they continue to rotate.
Time for the script:
To create I create the grid like this:
public function FlowerMenu(){
var rowY:Number = 0;
for (var i:int = 0; i < 190; i++) {
     var myCube = new               CubeMenu(["anemon.jpg","parodia.jpg","anagallis.jpg","lila.jpg","cosmos.jpg","adonis.jpg" ],100);
     myCube.x = 0 + ((i % 10) * 200);
     if (i % 10 == 0) {
         rowY += 200;
myCube.y = rowY;
addChild(myCube);
That works fine, although if anybody has any improvements I would appreciate them.
And now for the mouse events & event listeners:
private var i:int = 0;
private function setUpListeners():void
    spBoard.addEventListener(MouseEvent.MOUSE_OVER, boardOver);
    spBoard.addEventListener(MouseEvent.MOUSE_OUT, boardOut);
private function boardOver(e:MouseEvent):void
    addEventListener(Event.ENTER_FRAME, rotateSquare);
private function boardOut(e:MouseEvent):void
    addEventListener(Event.ENTER_FRAME, rotateSquare);
private function rotateSquare(e:Event)
    renderView(curTheta+i, curPhi+i);
    i++;
So, this works, but after about 4 or 5 cubes have started rotating the
performance drops considerably. I can imagine creating that many
EventListeners isn't a good idea, but I can't see any other way of
doing it.
Does anybody have any suggestions or code improvements, I'm very new to AS3
and Flash so any help or suggestions would be greatly appreciated.
Thanks in advance.

Actually I'm not using paper vision, I'm using the source from flash and math's using transformation matrixes and bitmaps here http://www.flashandmath.com/advanced/menu3d/index.html
No, the boardOut function, is for when the mouse rolls off the cube, it starts it spinning indefinitely.
private function boardOut(e:MouseEvent):void
    addEventListener(Event.ENTER_FRAME, rotateSquare);
If it helps I could post the project in a zip, so you can get an idea of what it is, i'm doing and can see where the performance hit is. Is there any recognised method of doing this on boards?

IChat screen sharing and video not working on MacBook but works on Mac pro

I have a MacBook and MacBook pro. Both have the lion os 10.7.2. I can use iChat on the MacBook pro for screen sharing, video chat, and text chatting, with others remote to me. However, I can only do texting with the MacBook. I can do screen sharing via Finder between my MacBook and MacBook pro. I can do FaceTime between both systems. I can also do FaceTime between the MacBook and anyone remotely.
I also tried installing teamviewer on the MacBook, and on a remote MacBook..... And I get the same results where I cannot share the screen, from the one that has not been working.
I have checked the settings under system preference and made sure screen sharing was enabled. I have checked under iChat under video to make sure screen sharing was checked.
The macbook that is having this problem is configured for AIM for iChat
I have run out of ideas. Any suggestions on what I might try?
Thanks

Ok,
I will list the ports in greater detail and point out when iChat uses them.
AIM Login and 1-1 Text Chatting
iChat version 1 through 5 will Log in to the AIM server on port 5190 (TCP Protocol) by default.
Since iChat 2 we have been posting here that the AIM servers allow a Login on almost any port and have been suggesting port 443.
This is used by both Web Browsers for secure Login to some sites and by the Mail app with some mail servers.
It is also below port 1024 (most domestic routers have the ports above this figure closed) In some campus situations using port 443 will normally allow at least Login and Text chatting.
iChat 6 uses port 443 by default.
File Transfers (AIM)
When doing File Transfers with AIM Buddies iChat will move to using Port 5190 on the UDP Protocol.
This cannot be changed. (This invokes the little Message about Starting Direct IM in an open Chat)
It also uses this port for Pics-in-chats, dropping Files on a Buddy's name with out a Chat or sending other files that are not pics.
In the case of Port Forwarding some devices don't like port 5190 being forwarded "twice" which is another reason for moving the login and Text chat port.
Jabber Logins
No matter what Jabber server you use ichat will use one of two ports (5222 and 5223)
Which one it uses is dependent on whether it needs and is using an SSL Login or not.
SSL Logins use port 5223 and NON SSL one use 5222 (ticking or Unticking the SSL box on a Jabber account will automatically change the port).
Google Talk is the exception in that it allow a Login on port 443 as well.
The First Apple Doc I linked you to says iChat uses port 5220 in Jabber.
I run Little Snitch and have never seen any version of iChat use this port at any time.
Bonjour
Any Mac to Mac Connection or Mac to any Bonjour able peripheral will be on port 5353.
This is normally opened (Preset) in the Mac Firewall for the Finder/System side of Sharing.
iChat needs and uses two other ports (5297 UDP and 5298 on both TCP and UDP)
As they an LAN Side connections the router would normally pass them.
At iChat 3 there were issues with the Mac Firewall (it included UDP set up and the preset in the firewall only listed them and TCP so we had people add all the iChat ports (you had to manually enter them in Tiger)
A/V Chats
No matter which Buddy List you start from iChat will do A/V chats the same way.
The Visible Invite you or your Buddy sends is on port 5678 (UDP)
In iChat 3 and earlier iChat then moves to port 5060 to send the SIP Connection Process invite behind the scenes (SIP = Session Initiation Protocol)
Port 5060 is one of 4 ports internationally agreed for SIP (How VoIP phones connect) (5060-5063).
Although ISPs were not supposed to block Through traffic many started blocking End users and then Charging them to open these ports (Many ISP were telecom companies that were losing long distant Telephone calls monies).
The SIP process then in iChat 3 contacts a server run by Apple for this purpose (Snatmap.mac.com to give it it's full name).
This acts like a old fashioned telephone operator connecting the call.
SIP is a text based process.
Your end "Calls" the operator.
The Operator "Calls" Buddy.
Buddy Accepts
iChat then negotiates the ports to be used.
In iChat 2 and 3 it uses 4 ports (vid in Vid out, Audio In and Audio Out) from "the group of 20" starting at the bottom (16384 to 16387 normally)
Three and 4 way chats uses more ports (which is why 20 are set aside)
In iChat 4 Apple realised the issue with the 5060 port and changed the way iChat worked
Since then it has Sent the invite on Port 5678 but then moved to port 16402 (it starts at the top of a smaller group of 20)
All Video and Audio traffic is also now on one port (so no need for 20 ports and iChat now lists 10).
NOTES so Far.
File Sharing during a Chat converts the Chat to Direct IM for AIM Logins
This is Peer-to-Peer in AIM
A/V Chats are Peer-To-Peer and you can actually log out of the Buddy list and continue the chat. (The exception is using iChat 6's AIM Video relay option)
Screen Sharing
Screen Sharing is an Audio Chat with a VNC connection along side.
Both bits have to wok to avoid the Pop-up to send to Apple and the Log that contains.
The Audio part is on port 16402 and the VNC part is random. (So random it is different every time you do it)
The reason it is classed as an Audio Chat+ is so the AppleScript for Auto Accept can filter out Screen Sharing connection and Not Auto Accept them.
This does have a knock on effect as far as your Router is concerned as already mentioned earlier.
You cannot Forward or Trigger the random Port so you have to use UPnP in your router to open the ports.
NOTES
Jabber File sharing may possibly be on port 1080 as listed in the Server Article I linked you to (I have also seen it written about in other stuff I have come across)
However Little Snitch does not seem to confirm this either.
Most time it will be peer-to-peer like the AIM connections for this.
However some Jabber servers do not seem to allow this and have this Jabber65 Proxy set up which passes things Server to Server in between it leaving your end and arriving at a Buddy.
This on Port 7777 but you do not need to open this port (unless you are running a Jabber server)
I have yet to test File Transfers using a Yahoo Buddy List in iChat 6.
AppleCare and Geniuses.
Previously I have been contacted by Geniuses in Stores asking to test customer's iChat.
They and the Applecare people have details about Apple wants an designed the App to work.
What they don't have is the knowledge about what it takes to set it up in the "real world".
There are literally thousands of Makes and Models of routers.
Some like the Thomson-Alcatel brand state they are SIP/VoIP ready but this means the router strips out all SIP Data trying to send it to a Phone.
Early models of Alcatels can get around this with a tweak. Later models can't.
Motorola devices tend not to have UPnP.
Apple Base Stations have Port Mapping Protocol instead of UPnP and this needs setting up.
The Zyxel range definitely does not like the dual use of port 5190 and does much better using UPnP (You almost certainly have to do your AIM login on port 443 with these).
1. I have two computers (MacPro and MacBook Pro) that are both running Lion 10.7.2 and both running iChat 6.0.1. <<-- Fine
2. The Netgear router model is: WNDR3700.    <<<<--- With any Brand there are exceptions and I do wonder about this one
3. The firewall for both Macs is turned on and in the advanced area iChat is listed as being "allowed." <<<<---- Fine
4. In iChat, under the video options, "Screen Sharing Allowed" is checked.                                        <<<<<---- Fine
5. In System Preferences, "Screen Sharing" is checked and this is for "All Users" at present.               <<<<<---- Not Required
6. There are two separate AIM accounts being used for iChat purposes.                                            <<<<<---- OK
7. In iChat preferences, each AIM account is "Enabled" under "Account Information" and the "Server Settings" show the Server as "api.oscar.aol.com" and the Port is "443" and "Use SSL" is checked.                                <<<<---- As it should be
From this and the other info in the first port it was only the router set up that seem to throw some light on a possible cause (Port Forwarding and UPnP conflict)
If just doing Port Forwarding the ports listed would have covered things (Except the Screen Sharing's random port)
Regarding your latest post.
I have table similar to that on my Sagem 2504Fast Modem/router combined device and it too seems to list a different port on the external side on occasions.
I would try the router with the Disable SIP ALG unticked (so it is not disabled). If the Help info on the right gives any info about what this Netgear version does it would be helpful.
Some are like the Thomson-Alcatels I was talking about in that it points the SIP data to a specific place (Possibly a Phone socket on the device)
Others seem to provide an "boost" to enable SIP to work and don't seem to get in the way of iChat.
Try adding the Names in Table 1 from this page and see if you can Video to those.
There are 6 names in total (I am actually only seeing one on Line as I type)

IChat, Parental Control and Bonjour

Rather than using AIM (and it's slowness), I was hoping to be able to use Bonjour on our internal network (which is firewalled and, obviously, not a threat) to chat/audio conference with our youngest.
I used the parental control to limit his AIM partners to the family but still wanted to allow him to talk on our network in the house. Unfortunately, when I go into iChat via his account the "using Bonjour instant messaging" is grayed out.
I tried turning it on in iChat on his account, going to my admin account and THEN enabling parental control, and trying again but no dice.
Any ideas?
Sure would be nice for home networks to have the option to iChat with everyone at Bonjour vs. AIM speeds (doubly so if you are on dialup!).

hi James,
Well I read this and thought "he can't be right" ?
So I went to test
Enabled Parental Controls and for iChat and Added one AIM/@mac buddy.
Looked for ability to add Bonjur or Jabber accounts but found nothing
Went to log in to that account.
Check to see if Bonjour window was available. Nope.
Checked iChat Preferences >Accounts and could not select Bonjour.
Took off Parental Controls - Appears in iChat, Bonjour and Jabber windows.
Selecting and deselecting Parental Control Logs iChat in and out of AIM.
I must admit to thinking this is a big Opps by Apple

How do I reinstall iChat, how do PC users video iChat with me, and should I just use skype?

1. I deleted iChat awhile ago by mistake. I searched ichat in Macintosh HD, and the only result was iChat the application file, but its icon is a faded out IWeb icon. When I click on it, it just bounces on my dock, until it disappears and an error message pops up stating it quit unexpectedly. I tried dragging the result to my desktop then redragging it into my Applications folder, but the same thing still happens (faded out iWeb icon instead of iChat icon, bounces, quits, error message). I also tried installing the iChat AV (forgot which version) and iChat Update 1.0 Universal, both of which said I had to have 10.4. I have 10.5.8. Also, if this makes any difference, the current faded out iChat in my Applications folder says its version 4.0.9. I do not have my reinstall CD, and do not want to call support and have them send me one. Considering I bought my macbook in late 2008, and my warranty is up, I'm pretty sure they wouldn't help me anyways. I also do not know of anyone who has a mac so the sharing option can be crossed offed. Is there a downloadable version of iChat for 10.5. users?
2. If I somehow managed to reinstall a working iChat, how would PC users connect to me and vide chat?
3. Should I just use skype? Would i have to download anything? Is skype video chat free? What are the differences between iChat and skype, and which one is better?
Thank you for your time!

Hi,
Reinstall Instructions
Be SURE to Download (Manually) and Install the COMBO version of the last Update to the OS you did as iChat will need to be Updated (Software Update will think it is already done and you need to Fool it)
Re 2).
In theory it is just a question oif you using a valid AIM name in iChat
This could be one registered with AIM or one from @mac.com or MobileMe if paid for or a current trial.
In Practice it can need a bit of tweaking at both ends
They Need to allow the AIM App through the Windows firewall as an Exception (AS with any Non Microsoft app)
They may also need to turn off the "Real Time" option that does not work to iChat and effects A/V chats as well. (It is Sending as you type). It will be in one of the Menus of their Budy List.
Post back for more if you get stuck.
Re 3)
Skype does offer free Video Chat and some people resort to it when iChat to AIM does not work.
It is free (At present - and you only pay for the Connection to and from real phones)
Skype was bought by Microsoft within the last week and things may change at some point in the future.
iChat has better Video
Audio depends on the capabilities of your Mac and their PC but is probably about equal.
Connection methods differ and iChat's Video and Audio Chats are technically more secure (you can in fact log out of the Buddy List as they adre Peer-to-Peer where as Skype uses a little bit of everyone's bandwidth (Between 40 and 100 other End Users)
Other options are here
Video options are from 8 onwards
Mebeam is now called Koowy. (Video Chatting in a Web Browser using Flash)
NOTES;
Google Do a Plug-in for Intels to allow you to use their Web Mail Page Chat Option
It can Conflict with Flash if you use more than one option.

Video chat between iChat Mac user and AIM pc user?

Me and my friend are attempting to video chat with each other via iChat for him and AIM for me. He is using iChat version 4.0.2 and I am using AIM version 6.8.10.1. When we send an video chat invitation it says that it timed out, could not connect. It sometimes kicks him off iChat, according to him. Can anyone help us solve this issue? Ty!

AIM said this about AIM 6.5 http://www.aim.com/helpfaq/starting_out/getstarted.adp#608
There is no information that they have posted that says AIM 6.8 is any better.
Some say it will work (AIM in General that is)
This is certainly needed http://www.ralphjohns.co.uk/page12.html#_Service to allow the app through the Windows Firewall.
In the AIM Preferences you will also have to select the camera in the Enhanced IM tab
The Mic should be selected in the control Panels as a System wide thing.
AIM since before AIM 5.9 has used port 1024-5000 as well as the Login on port 5190 and there is no reason to suspect it is any different now.
These ports will need to be allowed or open in your routing device.

Ichat very pixelated and audio lagging

Hi everyone. I have a 1 year old Imac and my niece has a brand new Macbook Pro she bought for college. She is at college and using their ethernet connection and when we try to video chat she is very pixelated and the audio very delayed. Not sure how to fix this problem but any suggestions would be appreciated. One other note, both computers have snow leopard installed. I don't have a problem with anyone else just her. Thanks

Hi,
Welcome to the  Discussions
For iChat 3 and 4 both of you should go to System Preferences > Quicktime > Streaming and set the speed to 1.5Mbps and restart iChat.
After that if you are still having issues the faster Internet Connected person should go to iChat menu > Preferences > Video section and set the Bandwidth Limit to 500kbps (Allow time for iChat to adjust).
Both of you should try this at different speeds. I would not go below 200kbps.
The reason for the last is that really fast Buddies can overwhelm the buffering that iChat has and it cannot "keep up" and drops frames.

IChat, t-mobile and their firewall

First, thank you defcom1 for your help this morning. I use t-mobile to connect wirelessly. I have noticed that skype has no problem connecting or video/audio chatting while I am on the t-mobile network. however, I cannot say the same for iChat. Apparently, it is a t-mobile firewall issue and not the program itself. Is their anyway to get the same functionality in iChat? I was last able to connect in a video chat on Jan.7 2007. after that, it all stopped. I use iChat for video interviews for my podcasts since I can capture the audio and video with ecamm's Conference Recorder. I can only capture audio with skype. It was suggested that I BUY another piece of software to capture the skype video. I think is nonsense. since should I purchase Snapz Pro, I will have spentover $100 for capture software: Conference Recorder, Audio Hijack Pro and now Snapz Pro?
GIVE US THE SAME FUNCTIONALITY AS SKYPE

Hi Kelly,
iChat is declared by Apple to be a VoIP application and therefore uses port 5060 to make the connection to your Buddy after the invite is accepted. This port is also above the 1024 threshold that on most devices (modem/routers) needs ports opened
Skype is also a VoIP app but they split the functionality.
This means to make a plain Video Chat they do not use port 5060. In addition the application has fall back ports below the 1024 threshold.
<hr>
If you have GarageBand 3 that will also record the Video and Audio from iChat (you have to have both apps open and start the chat before the recording in GarageBand)
<hr>
I am afraid you will have to talk to T-Mobile about their Firewall policy.
This is because Apple stick to the VoIP standards and iChat can not be moved from the SIP ports (5060-5063) nor in fact the other ports it uses for the A/V side - invites on port 5678 and the actual chats on ports 16384-16403.

IChat connection problems and no preferences to change

I have been receiving the "ichat connection alert" for the past three days. I researched it and the most common advice is to try logging into AIM from port 443 rather than port 5190. My problem is that when I go to ichat preferences the only thing I see is the A/V options. I do not see any other tabs. How can I get all the preferences options back?? This is an emergency since I use ichat to communicate with my clients.
Any help is appreciated!!!
Message was edited by: Host <to clarify Subject>

Thanks for your reply.
I went to preferences but did not see com.apple.ichat.plist. I searched my computer and found a couple of them in I'm guess old restore files(just a guess) and deleted those and restarted. No help. I opened ichat, but my contacts are not showing online when I know they are and I still only see the A/V menu in my preferences. Then after a minute ichat start disconnecting and connecting very rapidly. I just have to close it. Feel like I'm going crazy!

IChat agent quitting and logging me out of everything

This has been happening sporadically, but when I use iChat to log into my AIM and gChat accounts, I am sometimes logged out because of iChat agent dying and disconnecting. I am forced to log in again, and there are no problems again until it decides to disconnect again. It's not a huge problem that makes it inoperable, but if I'm having an important conversation and I'm suddenly logged out, it can get a bit more than annoying. I tried deleting the preferences for iChat Agent already, and it still does this. Anyone have any suggestions? Thanks!

Hi,
In Console (Applications/Utilities) are there any messages about it Quitting ?
If you use the Icon to reveal the Logs and the triangles to reveal more in ~/Library/Logs is there a Crash Reporter Log that lists iChatAgent ?
If the .plist did not sort it it maybe that iChatAgent needs to be Reinstalled.
As this is posted in 10.5.x you could try the COMBO Download first (You will need it anyway so don't through it away)
http://www.apple.com/downloads/macosx/apple/macosx_updates/macosx1058comboupdate .html
"Doing the COMBO" often sorts issues like this.
If not do the so called Hard Way here http://discussions.apple.com/thread.jspa?threadID=1486891&tstart=0
You swill see at the bottom it says about doing the Combo on the Reinstall (whether just the app or the support folders as well)

IPhone 5 iOS 6.1.4 and Windows 7 x64 USB Driver Issues

Been pulling my hair out with this one for the last week or so and haven't had any luck finding anything on the forums or the web regarding a solution short of a full reinstall of Windows 7 which I am not prepared to do at this time; so hoping someone here can shine some light on this for me
I have a iPhone 5 that is updated to iOS 6.1.4 and a recently built Windows 7 64-bit machine. All of my other USB devices function fine (keyboard, mouse, Xbox 360 wireless receiver for Windows, and a Seagate 2TB external USB drive). I've downloaded the most recent version of iTunes, installed successfully and then attempt to plug in my phone to sync. I get the standard Windows *ding* that I've attached a device and 1 of 2 things happens (I haven't been able to determine what causes one reaction to happen versus the other): Windows will successfully install the 'Apple USB Mobile Device Driver' successfully and it will appear under my USB devices in Device Manager. However - iTunes will not recognize the phone and I cannot see it in Windows either. In the 'Devices and Printers' snap-in my iPhone will appear under 'Unspecified Devices' as the 'Apple USB Mobile Device'. The iTunes diagnostics fail to find a connected device so the tests fail. As soon as I unplug the device, the strangest thing happens: Windows will start trying to install a device driver and after a few seconds it will fail stating that the "MTP Device Driver" installation failed because the device was unplugged. iTunes also thrown an error "iTunes cannot connect to this iPhone" throwing error code 0XE8000065 (I've also seen error code 0XE8000085 as well)
After some finagling, I've managed to get Windows to recognize the device under 'Portable Devices' in Device Manager as an "MTP USB Device" using the generic driver. At this point, I've tried updating the driver and manually specifying the Apple USB driver located in the C:\Program Files(x86)\Common Files\Apple\Mobile Device Drivers which updates successfully but then changes the device to "Apple USB Mobile Device" and moves it under the USB Devices in Device Manager; and Windows nor iTunes can see it even still.
I've tried removing iTunes several times and ensuring that all remnants of the installation are gone (registry and folders on the installation drive) and have disconnected all my USB devices short of the keyboard and mouse and still I get the same results. At this point, I'm afraid that a re-install of Windows is going to be the solution; but it's a drastic one (I have a SSD drive where Windows is installed along with all of my games for faster load times/better performance and do not want to have to redownload\reinstall all of them) and I'm not prepared to undertake it at this time, which is why I'm posting here
I've used a utility called USBDeview that sees my phone is connected - so I know from a functional standpoint that my USB ports are good and working. I also know the cable is good too - my daughter's PC (Windows 7 32-bit with NO iTunes) immediately sees the device when I plug it in, installs the drivers, recognizes it as an iPhone and I can then see/browse it in Windows Explorer like I would normally expect. My work PC (Windows 7 64bit, NO iTunes) sees the device just fine as well. I would immensely appreciate anyone that has seen this issue or has any additional solutions I can try.
It's also worth mentioning that I've never used Kapersky antivirus so the UPPERFILTERS value in the registry that I've seen as a solution on some forums is not present on my machine. I'm using Microsoft Security Essentials as my antivirus (no flaming please lol - it meets my needs and is extremely lightweight, which is why I'm using it on a gaming rig) and it's not indicating any issues. I've also tried running iTunes as an administrator (even though my account is a local admin on the machine) and that does not have any effect either.
If there is anything I left out, please let me know; and I thank you in advance!

Some features require a compatible video card to work; if the video card or its driver is defective or unsupported, those features will not work at all. Other features use the video card for acceleration and if the card or driver is defective those features will run more slowly.
Mercury Graphics Engine
The Mercury Graphics Engine (MGE) represents features that use video card, or GPU, acceleration. In Photoshop CS6, this new engine delivers near-instant results when editing with key tools such as Liquify, Warp, Lighting Effects and the Oil Paint filter. The new MGE delivers unprecedented responsiveness for a fluid feel as you work.
MGE is new to Photoshop CS6, and uses both the OpenGL and OpenCL frameworks. It does not use the proprietary CUDA framework from nVidia.
In order to use MGE, you must have a supported video card and updated driver. If you do not have a supported card, performance will be degraded. In most cases the acceleration is lost and the feature runs in the normal CPU mode. However, there are some features that will not work without a supported video card.

GPU/OpenGL preferences in Photoshop CS6
The advantages of using a compatible video card (GPU) with Photoshop are that you can experience better performance and more features. Problems can occur if you have an older video card with limited VRAM or if you use other programs at the same time as Photoshop that use the GPU.
Choose Edit > Preferences (Windows) or Photoshop > Preferences (Mac OS).
In the Performance panel, make sure Use Graphics Processor is selected in GPU Settings.
Click Advanced Settings and specify the following options:
Mode > Basic
Mode > Normal
Mode > Advanced Provides the benefits of Normal mode as well as newer OpenGL advances that can result in improved performance.
Use Graphics Processor to Accelerate Computation
Use OpenCL Uses the GPU to accelerate the new blur filters (Field Blur, Iris Blur, and Tilt-Shift) – OpenCL will only be available on newer GPUs that support OpenCL v1.1 or higher
Anti-Alias Guides And Paths Allows the GPU hardware to smooth the edges of drawn guides and paths.
30 Bit Display (Windows only) Allows Photoshop to display 30 bit data directly to screen on video cards that support it
Quick GPU Troubleshooting Steps
You can experience problems such as artifacts, errors, and crashes if there are incompatibilities between Photoshop and the display components that access the GPU.
If you experience crashes, incorrectly rendered windows or objects, redraw issues, or performance issues while running Photoshop, first determine whether OpenGL is causing the problem.
Turn off OpenGL.
Choose Edit > Preferences (Windows) or Photoshop > Preferences (Mac OS).
In the Performance panel, uncheck Use Graphics Processor. Click OK.
Restart Photoshop, and perform the same function.
If the problem recurs while OpenGL Drawing is disabled, OpenGL is not the cause. For additional troubleshooting, see Troubleshoot system errors and freezes | Adobe software on Windows (cpsid_82252) or Troubleshoot system errors and freezes | Adobe software on Mac OS 10.x (cpsid_82414).
If the problem resolves, proceed with the rest of the troubleshooting steps to fix OpenGL.
Make sure that you're using the latest update of Photoshop.Updates fix bugs and issues.
Update the display driver.Updated display drivers can fix many issues, such as crashing, incorrectly rendered objects, and performance problems. Determine what video card you have and go directly to the manufacturer's website (nVidia or ATI/AMD) and download the latest driver. (Note: Simply doing a Windows Update is does not guarantee you are using the latest driver. You must go directly to the nVideo or ATI/AMD websites to get the absolute latest driver.) After you update your driver, turn on Use Graphics Processor in Photoshop preferences.
Reset preferences.
Resetting preferences returns OpenGL settings to their default status. Reset Photoshop preferences by pressing and holding Shift+Ctrl+Alt (Windows) or Shift+Option+Command (Mac OS) immediately after you start Photoshop.
Click Yes when asked if you want to delete the Adobe Photoshop Settings File.
Retry the function that caused the problem.
Change the OpenGL mode to Basic.
Setting the OpenGL mode to Basic uses the least amount of GPU memory and the most basic GPU feature set.
Close all documents.
Choose Edit > Preferences (Windows) or Photoshop > Preferences (Mac OS)
In the Performance panel, click the GPU Settings Advanced Settings button.
Choose Mode > Basic
Restart Photoshop.
If this solution resolves the problem, switch to Normal mode. See if the issue recurs. If the issue recurs, return to Basic mode.
Note: If you’re changing GPU preferences to troubleshoot a problem, re-launch Photoshop after each change.
If you are using more than one video adapter, remove the additional cards.
Multiple video adapters can cause problems with GPU accelerated or enabled features in Photoshop. It's best to connect two (or more) monitors into one video adapter. If you have to use more than one video adapter, make sure that they are the same make and model. Otherwise, crashes and other problems can occur in Photoshop.
Note: Using two video adapters does not enhance Photoshop's performance.
Check your Cache Levels setting.
If you've set your Cache Levels to 1 in Photoshop preferences, you can experience performance issues with GPU features. Reset Cache Levels to the default setting, which is 4.
Choose Edit > Preferences > Performance (Windows) or Photoshop > Preferences (Mac OS)
In the Performance panel, choose Cache Levels > 4.
The GPU Sniffer
To help guard against Photoshop crashes related to bad GPU hardware or drivers, Photoshop employs a small program called the GPU Sniffer. Every time Photoshop is launched, Photoshop launches the sniffer. The sniffer runs rudimentary tests of the GPU and reports the results to Photoshop. If the sniffer crashes or reports a failure status to Photoshop, Photoshop will not use the GPU. The Use Graphics Hardware checkbox in the Performance panel of the Preferences will be unchecked and disabled.
The first time the sniffer fails, Photoshop will display a dialog indicating that it has detected a problem with the GPU. On subsequent launches the dialog will not appear unless the Photoshop preferences are reset.
If the user corrects the problem, either by replacing the video card or by updating the driver, then the sniffer will pass on the next launch and the Use Graphics Hardware checkbox will be enabled and returned to its previous state (enabled or disabled).
Tested video cards for Photoshop CS6
Adobe tested the following video cards before the release of Photoshop CS6. This document lists the video card by series. While the minimum amount of VRAM supported on video cards for Photoshop CS6 is 256MB, some features require 512MB of VRAM to be enabled.
Note: Adobe tested laptop and desktop versions of the following cards. Be sure to download the latest driver for your specific model. (Laptop and desktop versions have slightly different names.)
nVidia GeForce 8000, 9000, 100, 200, 300, 400, 500 series
nVidia Quadro 400, 600, 2000, 4000 (Mac & Win), CX, 5000, 6000
AMD/ATI Radeon 2000, 3000, 4000, 5000, 6000, 7000 series
AMD/ATI FirePro 3800, 4800, 5800, 7800, 8800, 9800, 3900, 4900, 5900, 7900
Intel Intel HD Graphics, Intel HD Graphics P3000, Intel HD Graphics P4000
Note: ATI X1000 series and nVidia 7000 series cards are no longer being tested and are not officially supported in CS6 – some basic GL functionality may be available for both these cards.
Note: 3Dand some Open GL features are disabled on Windows XP, as stated on : http://labs.adobe.com/technologies/photoshopcs6/

Hi James,
Could you give me a call, I am at my desk.
I had meetings all day and couldn't respond to your calls earlier.

Subject: Re: Case 59063: performance issues w/ C TLIB and Forte 3M
Hello,
I just want to reiterate that we are very committed to working on
this issue, and that our goal is to find out the root of the problem. But
first I'd like to narrow down the avenues by process of elimination.
Open Cursor is something that is commonly used in today's RDBMS. I
know that you must test your query in ISQL using some kind of execute
immediate, but Sybase should be able to handle an open cursor. I was
wondering if your Sybase expert commented on the fact that the server is
not responding to commonly used command like 'open cursor'. According to
our developer, we are merely following the API from Sybase, and open cursor
is not something that particularly slows down a query for several minutes
(except maybe the very first time). The logs show that Forte is waiting for
a status from the DB server. Actually, using prepared statements and open
cursor ends up being more efficient in the long run.
Some questions:
1) Have you tried to do a prepared statement with open cursor in your ISQL
session? If so, did it have the same slowness?
2) How big is the table you are querying? How many rows are there? How many
are returned?
3) When there is a hang in Forte, is there disk-spinning or CPU usage in
the database server side? On the Forte side? Absolutely no activity at all?
We actually have a Sybase set-up here, and if you wish, we could test out
your database and Forte PEX here. Since your queries seems to be running
off of only one table, this might be the best option, as we could look at
everything here, in house. To do this:
a) BCP out the data into a flat file. (character format to make it portable)
b) we need a script to create the table and indexes.
c) the Forte PEX file of the app to test this out.
d) the SQL staement that you issue in ISQL for comparison.
If the situation warrants, we can give a concrete example of
possible errors/bugs to a developer. Dial-in is still an option, but to be
able to look at the TOOL code, database setup, etc. without the limitations
of dial-up may be faster and more efficient. Please let me know if you can
provide this, as well as the answers to the above questions, or if you have
any questions.
Regards,

w/ CTLIB and Forte 3M
We did that trick already.
When it is hanging, I can see what is doing.
It is doing OPEN CURSOR. But not clear the exact statement of the cursor
it is trying to open.
When we run the query directly to Sybase, not using Forte, it is clearly
not opening any cursor.
And running it directly to Sybase many times, the response is always
consistently fast.
It is just when the query runs from Forte to Sybase, it opens a cursor.
But again, in the Forte code, Alex is not using any cursor.
In trying to capture the query,we even tried to audit any statementcoming
to Sybase. Same thing, just open cursor. No cursor declaration anywhere.==============================================

Like:

- how did you test
- what data do you have, how is it distributed, indexed
and so on.
If you want to find out what's going on then use a TRACE with wait events.

Is there a recommended limit on the number of custom sections and the cells per table so that there are no performance issues with the UI?

Is there a recommended limit on the number of custom sections and the cells per table so that there are no performance issues with the UI?

Thanks Kelly,
The answers would be the following:
1200 cells per custom section (NEW COUNT), and up to 30 custom sections per spec.
Assuming all will be populated, and this would apply to all final material specs in the system which could be ~25% of all material specs.
The cells will be numeric, free text, drop downs, and some calculated numeric.
Are we reaching the limits for UI performance?
Thanks

Performance Issues with 10.6.7 and External USB Drives

I've had a few performance issues come up with the latest 10.6.7 that seem to be related to external USB drives. I have a 2TB USB drive tha I have my iMovie content on this drive and after 10.6.7 update, iMovie is almost unusable. Finder even seems slow when browsing files on this drive as well. It seems like any access to the drive is delayed in all applications. Before the update, the performance was acceptable, but now it almost unusable. Most of the files on this drive are large dv files.
Anyone else experience this?

Matt,
If you want help, please start your own thread here:
http://discussions.apple.com/forum.jspa?forumID=1339&start=0
And if your previous thread you aren't getting sufficient help for your iPhone, post a new topic here:
http://discussions.apple.com/forum.jspa?forumID=1139
You'll get a wider audience, and won't confuse the original poster. Performance issues can be caused by numerous issues as outlined in my FAQ*
http://www.macmaps.com/Macosxspeed.html
If every person who had a performance issue posted to this thread, we'd never find a solution for the initial poster. Let's isolate each case one by one. It is NOT necessarily the same issue, even if the symptoms are the same. There are numerous contributing factors at work with computers, and if we don't isolate them, we'll never get to the root cause.
