GPU not being used at all. (gtx 860M). Lenovo Y50-70 laptop.
Hello!
I recently upgraded to windows 10 via windows update and did a clean install after the upgrade. Installed all the neccesary drivers etc etc. The usual drill. I consider myself rather tech savy.
After a few days of casual gaming with LoL i noticed that my Nvidia GTX 860M GPU was not being used AT ALL, only the integrated Intel HD 4600.
This was further proved to be right after I installed Path of Exile and kept getting BSODs each time after around 10 minute of playing with various error messages revolving around the file "igdkmd64.sys". I've tried completely deleting the drivers using safe mode and the driver cleaner program and reinstalling other drivers (ex. the lenovo driver dated 14/7. ) with no luck.
I've tried all the settings within intel hd graphics and nvidia controlpanel. I've also tried checking BIOS. No luck there either.
Both of the GPU's also show up in device management without any issues.
I also tried disabling the intel hd graphics within device managent which resulted in the basic adapters being used and my screen looks bad... My current Nvidia driver is 353.62. I'll post some various screenshots here:
Device management with both activated:

Nvidia control panel with both GPUs active in device management:
http://bildr.no/image/L3lYb1ZC.jpeg
This shows up when I try to check Nvidia display settings when intel HD graphics is DISABLED in device management. It basically translates to:
"Nvidia displays ettings are not available. You're not using a display connected to a Nvidia GPU"

My display settings options with intel HD graphics being disabled:

Can provide further information if required. Not sure what you need to know, but bottom line is that my GTX 860M GPU is not being used for anything at all.
i'm assuming that all I can do for now is to either wait for updated drivers from lenovo or to roll back to windows 8.1 (Works fine in win 8.1)?
More than a fix I think it has more to do with the graphics drivers and in some cases Windows 10 installation issues.
About the Graphics drivers,
Try uninstalling the NVIDIA GPU in Control Panel > Device manager
Uninstall everything related to NVIDIA in Control Panel > Prgrams & Features
Restart the system and wait for it to install the NVIDIA GPU again.
I would also advise that you try older drivers, if they are available.
About Windows 10 Installation,
I have installed Win 10 twice now. In my previous Win 10 installation my system was running slow, Cortana was not working and couple more issues.
In current installation, everything is working great till now.
What I did different in second installation -
I installed all drivers upgrades for Win 8.1
All windows updates for Win 8.1 before upgrading to Win 10
I downloaded Win 10 ISO and started Win 10 setup from a bootable USB (by running Setup file while logged into windows 8.1)
During upgrade, I did not Apply Updates for Win 10 (Selected the bottom option)
Then windows installed normally
Updates to Win 10 were applied after installation.

Insane performance issue. GPU not being used at all for cropping.
I regularly record my screen and later open the resulting file in Pr and export only a square on it. I import the video, maybe cut away some fluff, and export, choosing to crop it.
The result is a painful ordeal that cripples my computer for hours every single day, where Premiere Pro CC uses almost 100% CPU constantly, but 0% of the GPU. It's really extremely slow. Other export tasks seem to be as quick as you expect them to be. But not this particular job, which I rely on every day. Very annoying.
There is simply no way that this is intended. The GPU seems to be made for things like this. Why isn't Pr using it?
I have 20 GB RAM, a very powerful quad core Xeon, a new Nvidia GPU, solid state disk, etc. Windows 8.1 Update 1. My computer is never slow for other tasks. This is really a very annoying issue as it makes using the computer nearly impossible for hours a day. For no good reason. It needs to use the graphics card to crop!It just really annoys me that this kind of thing is ever turned off, hidden away and just... ambiguous.
Its hardly hidden away. Its in the NEW PROJECT Settings page and first setting drop down option.
There are reasons why its an option... buts its ON by default on any new project I start. -
Ultra low frame rates, GPU not being used
While using After effects during playback, I am getting about 10-4 FPS. With frame rates that low it's basically impossible to make any videos. I am using a desktop gadget to monitor GPU usage. I noticed that my GPU is not being used at all, 0% usage and only a few MB of memory being consumed out of 4 gigs of GDDR5. I called Adobe customer service and basically I was told that After effects only uses as much GPU power as it needs to. Ok, that makes since and If I was getting 30+ FPS then I wouldn't care, but it seems odd to me that After effects is running so poorly and not using my GPU. If my GPU was maxed out, then I would understand I need a more powerful GPU to improve frame rates, but since my GPU is not being used at all, not even a bit then I don't think it's a hardware problem, but some sort of setting that is not right. The only thing I could think of is that my HDD is pretty slow or that GTX cards are not designed to run Open Gl and maybe that's the problem, but I double checked the Adobe website and GTX cards are supported. Also I downloaded some other GPU monitoring software to double check and both the Desktop gadget and the GPU software monitor show no activity. I am really new to After effects. Thanks for help.

Well, it doesn't.
AE is an effects, motion graphics and compositing application. It's designed to do completely different things than an editing application does. Hence, it doesn't work like an editing application does. For example, IT DOESN'T PLAY BACK VIDEO IN REAL TIME. That's why you got that getting started link. At least do yourself the favor of reading how AE works.
And for the purposes of this thread, it wouldn't hurt you to learn how to RAM Preview: hit zero on the numeric keypad and see what happens. It's just one of the many basics you need to know before you jump into the deep end of the pool with AE. -
CE500 CFS Disk is not being used at all
This is a new installation using WCCP v2. Even though the engine is registered with the IOS router and the router is definitely forwarding traffic to the CE, no disk space is being utilized at all and my savings is reported as 0. I've verified that the CFS volume is mounted successfully. Here is my current CFS disk stats:
Volume0 49.754 G 0 K 0 K 0 K 0 K 0 K
Thanks in advance.This happens when you get a lot of disk errors . This is most likely the cause of the problem. Reconfigure the disks and reboot. Once the CE comes back up, let it run for sometime after which you could check if you are getting any logs on your CFS disk.

I have just updated to latest version of LR and it is not using my GPU. In LR system info it says it is but if I monitor my GPU clock speed then I can see it is not using it.
If i run PS i can clearly see my GPU clock speed increase so I know it does work.
Any ideas?More than a fix I think it has more to do with the graphics drivers and in some cases Windows 10 installation issues.

I've used an external drive for time machine which has important files on it. After trying to back up my computer, it suddenly needed to be "repaired" by utilities. Now it's not being "seen" at all! How do I recover my important files off the drive?
If the external drive can be seen at all in Disk Utility, follow the instructions for repair here.

my battery drains even when iphone is not being used. It is a relatively new phone and this battery draining just started and I can't figure out why????
Yes, thank you. My apologies, I was typing one handed and did not add that.
Anyway, I have tried deleting the cache, deleting my pics and then re-syncing, etc. and nothing is working This is very frustrating, as I had no problems up until about 2 weeks ago, and now all of a sudden, I have this issue......UGH! -
HBOgo "StageVideo is not being used"
I just updated flash today, November 25 2013, which gives me version 11,9,900,152. The problem I'm having seems specific to the HBOgo.com site.
The problem occurs in all three browsers that I've tried, Firefox (my preferred browser), Chrome, and IE 9. Also, I've tried the various suggested troubleshooting suggested on the Adobe site as far as enabling Flash addon in IE after disabling (unchecking) the choice for ActiveX filtering. I've tried uninstalling/reinstalling all 3 browsers, reinstalling flash, resetting all video card settings to default, going through the Device Manager and uninstalling the device entirely, making sure it has no errors or conflicts anywhere and the same thing for the network devices, they all indicate that they are working properly.
My device is an HP Pavilion dv7 Notebook PC running Vista Home Premium Service Pack 2. It has 4 GB of memory and the video card is an NVIDIA GeForce 9600M GT. The drivers are all up to date and so is every application and its associated add-ons that I will mention. Also, it shipped with a Blu-Ray player which I've used to display Blu-Ray content on an external monitor with no issue. (If it can do that, then shouldn't it just be some software issue preventing it from playing back a video stream of inferior quality from hbogo?)
Regarding Flash Player, I've watched videos on YouTube and Hulu (and countless other sites which stream Flash Video) at resolutions of 720 and 1080 which played at framerates between 25 and 30 fps and which also did not use hardware acceleration but nevertheless maintained CPU usage of less than 70%. So, the computer can certainly do it even without the help of the GPU, and it can do it from other sites that use flash, but not from HBOgo. That's a second problem, even when flash video plays well, it's still not using hardware acceleration, but first I want to know why HBOgo's flash player is so much worse than everyone else's player.
Here is the specific issue: I navigate to HBOgo.com, pick any video to play and begin playback. Playback usually begins at a relatively low resolution (I'd guess 480 or so based on its obvious pixelation), and then steps up the resolution gradually. Usually after a minute or so, it will have reached its best resolution and that's when it starts dropping frames like crazy and pinning the CPU at 100%. The video looks terribly choppy and the audio skips the more choppy the video is. When I click pause or hit the spacebar for a pause, it will take two or three seconds as it spits out the last few video frames before finally showing the paused icon on the last frame. Those two seconds seem to corrolate with CPU processing since there is no noticable delay when pausing video anywhere else under any other conditions. Of course, CPU useage will drop back to 5 or 10 while the video is paused.
Right-clicking the screen lets me choose "Show Video Debug" which in turn tells me:
StageVideo enabled in OSMF: Yes
StageVideo is supported.
StageVideo is not being used, regular video 'probably' is.
This is where I got the information about dropped frames. If it matters, when paused, the buffer will fill to about 400 Mb plus or minus about 10 percent of that, perhaps. Also, during playback, the buffer maintains approximately the same amount, indicating that my ISP has no problem sending that much data to my device. The buffer seems fill to a lenght of time, about 60 seconds; so, as the video resolution goes down, the total buffer drops accordingly... sometimes it is at 200 Mb for 60 seconds with lower resolution, etc...
Speaking of my ISP, I have Verizon FiOS (I don't know why it would matter, but I'm in King of Prussia, which is near Philadelphia, PA). I just tested my bandwidth and it tells me that my IP is 71.175.97.244 and my download rate is 57.98 Mbps from some server in Matawan, NJ. I don't think networking issues factor into this at all. I say that because, digging into the developer tools (all 3 browsers show the same network activity: Firefox, Chrome, and IE) and clicking on the "Network" column, it consistently shows low latency for all the stream components. For example:
path: http://hds.pro12.lv3.hbogo.com/videos/PRO12/e2/hbo/feature/728425/hbo_821867_PRO12_f4m/hbo _821867_PRO12_8-Seg1-Frag858
method: get
type: video/f4f
Timing Tab show:
Sending: 0 Waiting: 89mg Recieving: 159ms
This seems to indicate that I'm getting the data sent to me without any problem, so forget about network issues, right?
Also, regarding information available in Developer Tools, I can see that the flash video object has the paramater "wmode" set to "transparent". I already wasted time messing with this before I realized that the paramater is irrelavent while in fullscreen mode -- besides the fact that even when it is changed to direct or gpu when not in full screen, it does nothing to help matters. I think this was covered in one of the last discussions talking about lack of hardware acceleration on HBOgo -- the same discussion that ended with a few people saying that they were going to "throw in to towel".
What am I missing here? Why is StageVideo supported but not used? Why do other players which use flash play videos with better quality despite still not using hardware acceleration?
Windows Vista = updated
NVIDIA Video Drivers = updated
Flash Player = updated
Flash Addons (pepper flash, etc...) = updated
Firefox, Chrome, IE = all updated
There's got to be something I can do. What is it?Hello Sarvanan,
What do you mean by "the respective field not having the Unit/Curr Objects"..?..some of them are of the type "number" whereas others are CHARS.
Everytime when i add some field i cannot re-create the whole transformation. There has to be some inconsistency as my mapping of source-target field is correct. I have also raised this to OSS but as usual they are taking thier own sweet time to reply.
Surprisingly the transformation got activated yesterday and the dataload too was successful. Today again the same ols problem of "parameter is not being used"..!!
still could you pls throw some light on Unit/Currency objects that u mentioned..??
Thanks in adv.

Target parameter is not being used
Hello,
while activating the transformation, i get an error saying" Target parameter 0058 is not being used". I have checked all the rules, infoObjects etc. but still im not able to activate the transformation at all.
Eventhough the source field-target field mapping is correct, the system is throwing such errors. What could be the possible cause of it. Any idea?

I have pulled it out of the box and put 2 Mac approved mem sticks in it to boost it to 8 Gigs mem and it still locks up and freazes.. So many people told me Mac was the way to go... 1500 dollers could have bought me a great pc laptop. Now I have a wirless mouse keyboard and a mac mini (aka Brick) that allowed me to donate money to a cause that is helping buildings and companies out side of the US. While I have junk.. It's still under warranty and I reinstalled the os after the new mem sticks. Again.. locks up and does nothing. What can I do with this? Toss it in the trash? Any info on what I might do with it.. Please help!
It would be most helpful if you updated your system information:
Please reconcile the following
at 18 day's old it started to lock up and not function. Took it in and they wiped and reinstalled it. Well at 24 day's old it's been sitting in the box not being used.
... I reinstalled the os after the new mem sticks.
If your Mini is anything less than six months old it would be running Lion, not 10.6.1, nor would it have been necessary to "reinstall the OS". Any help that anyone can provide is predicated on your system configuration so it's important.
If you are running Lion then boot your Mini while holding the D key. This will load Apple Hardware Test which will enable you to test your memory. "Mac approved" memory is sort of vague, and even memory that is allegedly designed to meet your Mini's specification may fail. There few reputable memory vendors.
"Apple installed" memory is more meaningful, and indicates Apple has tested it and guarantees its function. Otherwise all bets are off with a claim of "Mac approved". You will have to verify that yourself with Apple Hardware Test.
If your Mini was running, or ever ran OS 10.6.1 for that matter, it is close to three years old.
You must clear up these uncertainties before anyone can help. -

IMac (Oct 2009) keeps shutting down and restarting when not being used.
At least once a day, usually when not being used, I will see a dialog box that say computer had to restart due to a problem. data in problem report does not clearly state problem - many multi-page entries
Have reinstalled OS 10.8.2 once
this morning tried to restart with safe boot and had spinning beach ball for more than 15 minutes. shut down and restarted nin recovery mode. verified and repaired permissions (all seem to be related to Canon Pronter plug-ins- had an error message yesteday asking if I wanted to repair printer software and I said yes). Printer seems to be working. Had one statement that indicated a screensaver issue-see below
a while back, iTunes album art screensaver hung up with just two album covers flipping in all rows and columns.
after a few restarts, it started working correctly again..- yesterday I set screen saver to never, but still had a crash this morningHere's the latest panic report. BTW, I ran for a while from an external system boot - very sloww (thumbdrive), but nothing happened. However, when I retarted I tried to restart in Safe Mode and the launch never completed (30 minutes without start)

How to tell which Indexes are not being used?
We are a large development shop and have many customers. Our database design is very generic so that it works for all of our customers. Each night we use an SSIS ETL process to bring down large amounts of data from the iSeries into SQL. One
particularily large customer takes a very long time and we are looking for ways to speed up thier data import and transformation. I would like to see which indexes he does not use and possibly remove them. Each night we fully repopulate hundreds of staging
and ods tables and incrementally delete and repopulate the days work for a handful of history type tables. Removing some indexes off of the large tables could make a big impact.
How can i tell which indexes the customer does not use?> IDENTIFYING UNUSED INDEXES IN A SQL SERVER DATABASE
Just because an index is not being used does not necessarily mean it should be removed.

José Diz Belo Horizonte, MG - Brasil -
Dear All,
Having real trouble these days with the indexes.
I have a query below:
SELECT MAX(A.ID) PRID,TIMEPERIODID,RESOURCEID
FROM TIMESHEET A, TIMEPERIOD B
WHERE A.STATUS IN (1,3,4) AND A.ISADJUSTMENT = 0
AND A.timeperiodid = B.id
AND TRUNC(B.PSTART)>=TRUNC(NEXT_DAY(SYSDATE-28,'MONDAY'))
GROUP BY TIMEPERIODID,RESOURCEID
The explain plan for this query is as below:
Plan COST
SELECT STATEMENT 2720
SORT GROUP BY 2720
HASH JOIN 2520
TABLE ACCESS FULL TIMEPERIOD 2
TABLE ACCESS FULL TIMESHEET 2516As you can see, table access full on timesheet table. However, I have an index on timeperiodid column of the table. Despite using it as hint, the index is not being used. Is it that indexes are not used with GROUP BY?
Please help.
Thanks,and the explain plan:

Newly created index not being used
Hello friends,
I am observing that a newly created index on a z table with mandt & a new field is not being used. I have already rebuild index & updated stats for table.
when we query on this table with where clause having same 2 fields mandt & other.. we expected this index to be used. This table is very large. What more i can do now ?
In trace/SQL session, we can see it is going full table scan.. and takes very long time.
this new field contain no data as of now for all existing rows. Is this the reason ? or sometihng else ?

Hi,
with this WHERE clause, both columns just one distinct value, the Full Table Scan is indded the best approach, beside
the point you only need a check to evaluate a value is NOT in the result.
In this case you should HINT the statement to the new index, because the DB will always assume that this index is non-selective.
