Why do I get low frame rate for games while charging?

I have a Lenovo g505s laptop , and when I play games while charging(plugged in) , the frame rates for every game drop to 15-20 fps. Is there any driver update that I require? Or any other solution to this problem?

hi thematrix01,
Welcome to Lenovo Community Forums!
Can you try running a BIOS update and see if that will fix it.

JPEG viewing low frame rate.

Hi, I am trying to play a list of jpeg files using player, as if it is a jpeg movie. But I am getting low frame rate, like 10 fps. However, by using the same jpeg files, and make it in a .mov file, the player could play it at 30 fps (the setting during making the stream). The .mov file is produced using the same setting as the program JpegImagesToMovie posted on the forum.
The testing applet that run the movie in full rate is (simplified, without exception catching):
url = new URL(getDocumentBase(), mediaFile);
mediaFile = url.toExternalForm();
MediaLocator mrl = new MediaLocator(mediaFile);
Player player = Manager.createPlayer(mrl);
player.start();
For the JPEG file stream, the player is created as:
Player player = Manager.craetePlayer(customdatasource); // refer to below for the custom data source class
1. Is it I need to make the data source format to something else , so that the player will play it with 30 fps instead of the slow 10 fps rate?
2. How would a player render a jpeg image faster? I checked the timing, the loading time for each jpeg file is less than 1 ms, but it took the player around 100 ms to render the loaded image.
I created my own PullBufferDataSource and PullBufferStream. Below is the list of my program. I make the datasource and datastream to load a image file each time the:
read( Buffer buf)
method is called in the datastream class.
public class MJPEGDataSource extends PullBufferDataSource {
protected InputStream sourceStream = null;
private MJPEGDataStream streams[];
public MJPEGDataSource(int width, int height, int frameRate, String sourceFile) {
     streams = new MJPEGDataStream[1];
     streams[0] = new MJPEGDataStream(width, height, frameRate, sourceFile);

public class MJPEGDataStream implements PullBufferStream {

     int width, height;

FileInputStream infile = null;
public MJPEGDataStream(int width, int height, int frameRate, String sourceFile) {
eofMarker = true;
this.width = width;

((in[1] << 8) & 0x0000FF00) + ((int)(in[0]) & 0x000000FF);
return result;

Hi again.
I found the solution to my problem. In the read(Buffer buf) function, the buf timestamp and sequencenombur should be set in order to play at the expected frame rate (30 fps in my case):
public void read(Buffer buf) throws IOException {
if (infile.available() <= 0) {
System.err.println("Done reading all images.");
buf.setEOM(true);
buf.setOffset(0);
buf.setLength(0);
eofMarker = true;
return;
byte data[] = null;
if (buf.getData() instanceof byte[])
data = (byte[]) buf.getData();
byte byteSize[] = new byte[4];
infile.read(byteSize);
int size = byteToInt(byteSize);
if (data == null || data.length < size) {
data = new byte[size];
buf.setData(data);
infile.read(data, 0, size);
buf.setOffset(0);
buf.setLength(size);
buf.setFormat(format);
buf.setFlags(buf.getFlags() | buf.FLAG_KEY_FRAME);
// ====== added line ========
long time = (long) (seqNo * (1000 / format.getFrameRate()) * 1000000);
buf.setTimeStamp(time);
buf.setSequenceNumber(seqNo++);
Thanks for reading.

Why lose mbps when conform to lower frame rate?

When I export a QT pro res HQ movie out of MOTION 4, with the same settings as the sequence (Pro res HQ 422, 59,96 fps 1280x720p), it renders out a good, same 221mbps file, but when I then take that file into Cinema Tools and conform it to 23.98fps, the file is now 88mbps? Why and how, and did losing 140mbps somehow lose also color correction and other quality capabilities?
Why does CT lose many mbps when conforming to lower frame rate?
Thanks
K

Thanks fo replies - I shot in 60 fps 720p to purposely slomo the shots in MOTION using Optical flow - then I conform to 23.98 using Cinema Tools, though I guess I could do the same by exporting to 23.98 out of MOTION 4. Wonder if there is any advantage or otherwise using CT over MOTION export to 23.98?
Nick is right, I can see a decline in visual quality/sharpness in the footage now conformed at 23.98. Should I export out of MOTION at PR HQ or 4444 or uncompressed? Hoping to preserve what I think is 10-bit footage recorded on ATOMOS NINJA at PR HQ422, which is 10 bit correct? But when I choose PR HQ 422 in MOTION export, it says (at the bottom summary of my codec) that it's HQ at 8-bit? Why and how to preserve 10-bit for color grading?

9400M intermittent low frame-rate : let's get heard !

hello
i have the exact same problem described on this thread
http://discussions.apple.com/thread.jspa?threadID=2085771&tstart=1
" Has anyone else noticed, the performance of the NVIDIA 9400M graphics chip is intermittent. Sometimes everything will be fast and smooth and fluid, and suddenly it will switch to having a low frame rate.
A good example of this is in iPhoto's Full-Screen Edit mode. As you tap through the image with the right/left arrows, the animation can be quite jerky and slow. Then suddenly it will switch to being really fast.
Have Apple just not optimised the NVIDIA 9400M graphics drivers yet? Will its performance be better in the near future? "
sam problem, except it's on a 24" iMac . (latest one - 2 X 2.66 ghz + 4go RAM + 9400m)
the problem happens constantly when i use my firewire soundcard. guess what : i'm a musician, and my firewire soundcard is on all the time !
it also happens when i copy files from my external firewire hard disk, or if i use my macbook on target mode.
the only way to make this problem disappear is to switch to 1280 X 960 resolution (or below). therefore the 9400M has enough power to overcome the drain created by ... either bad drivers or a problem with firewire... i don't know.
anyone knows when the drivers will be updated ? if a new firmware is in the work ?
thanks

i guess not so many people use the firewire 800 port.
had to pay 15 euros to get a 800>400 cable, so no wonder ...
here's my bug report
hello
here's my setup :
iMac 2.66 ghz / 4 gigs of RAM / 640 go HD / Nvidia 9400M graphic chip
Leopard 10.5.7
when any firewire device is in use, the frame rate switches from fast / fluid to slow / lag-ish.
simply launching Dashboard shows the frame rate drop. same problem with Expose.
the problem happens exactly the same weither i use my firewire soundcard (echo audiofire 8), my external hard drive (WD mybook 750 go) or my macbook in target mode.
the problem disappears when i turn off my soundcard, or when the external hard drive is idle. another way to "fix" the problem is switching to a lower resolution ( 1280 X 960 ).
i've spent more than 30 minutes with apple on the phone, we did a lot of tests, and the technician came to the conclusion the computer was perfectly working.
this definitely looks like a driver problem.
i've started a discussion about the matter here :
http://discussions.apple.com/thread.jspa?threadID=2085911&tstart=0
some users have the same problem :

One swf running on lower frame rate

Hi,
I have a basic loader swf, which loads several external swf's and displays them in a browser. Now all the other swfs work just fine, at 24 fps, but one particular swf drops down to 12 or 11 fps in the middle of the timeline. Why is this happening?? And how can I get it to run at the same frame rate as the others.
There is some heavy animation in all the external swf's but that does not seem to affect any other files, only this one. Also, the animation is not heavy throughout, though the low frame rate persists...
What could be wrong???Any help will be greatly appreciated..as the entire site is looking bad because of this file...:|

Have you tried just loading the problematic file? Does is play better? Does this problematic file play correctly alone?

NVidia GT 120 and intermittent low frame-rate with Expose, Dashboard...

I have an iMac early 2009 with a NVIDIA GeForce GT 120 (256 Mo) graphic card.
I have intermittent low frame-rate problems with Expose, Dasboard and several other large animations...
For example, when I trigger Expose or Dashboard, the animation may sometimes be choppy (with few intermediate images) to very choppy (practically no intermediate images)...
The second after, the same animation may feature a very high frame-rate...
Neither Apple diagnostic tool nor TechTool Deluxe finds any hardware problem.

I have the same iMac, and also have this same problem.
When I first activate Dashboard, the animation is choppy. If I activate it several times in a row very quickly, the animation smooths out noticeably. It's as though the video card is asleep, or cycled down, and then wakes up and springs into action.
This is testable. If I run the command line utility OpenCL Bench immediately following a restart, my iMac's GT 120 gives a time of 14 seconds. If I open iTunes, turn on the visualizer, and then run OpenCL Bench again, the GT 120 gives a time of 1.7 seconds! If I turn off the visualizer, wait a few seconds, and re-run OpenCL Bench, the GT 120's time increases to 5.6 seconds.
The same performance increase/decrease shows up with Dashboard. If I open Dashboard with the iTunes Visualizer running, right off the bat, Dashboard's animation is very smooth. If I turn off the visualizer and wait about 30 seconds, Dashboard's animation is back to choppy.
This is not dependent on the iTunes Visualizer. I can have the "OpenCL Procedural Grass and Terrain Example" running, for example, and get the same results from OpenCL Bench and Dashboard.

Best frame rates for 4 different cameras in multicam

Well, I've been flopping around in different threads on this forum, but I think the question is beginning to finally take shape for me. Basically it's all about deciding on frame rates for four different cameras I will be using to shoot a 6-day intensive course I will be teaching. The video will be primarily for computer viewing (YouTube, Quicktime movies). Here are the cameras:
2 new Canon cameras capable of frame rates of 60i, 30 frames per second progressive "recorded as 60i", and 24 frames per second progressive also "recorded as 60i" (there is a known issue with importing the 30 frames per second into fcpx, as fcpx does not recognize this as progressive, but ClipWrap can get around this).
1 Sony capable of 60i, 60P, and 24P
1 Sanyo capable of 60i and 30P
Possible settings:
Just do all at 60i, but people say this is not so good for computer viewing
Canon at 30 fps (using ClipWrap to see it gets recognized as progressive), and the Sony and Sanyo at 60i. Will this cause syncing or other problems, mixing frame rates like this? How bad a hit in quality is 60i on computer screens?
Canon and Sanyo at 30 fps, Sony at 60i
Same as #3, but use JES Deinterlacer to get Sony 60i to 30 fps.(I tried this out, by the way, and the resulting frame rate, after deinterlacing, showed up in the inspector window at 30, not 29.97. Is that a problem?
Anyway, I aplogogize for wearing out my welcome on this forum, and I thank everyone for creating such a wonderful bank of information.

Not sure what you're trying to achieve here - for the best overall quality, if possible, choose a frame rate that all the cameras can achieve. That way you won't lose quality in the conversion.
If you're not satisfied with that, you need to do some tests to see which gives you the effect you like best. Nobody here can help you really - it's up to you.

Frame rate for camera does not match with AVI output

Hello,
I'm taking a video from a Basler A504K camera of well plate bottoms deflecting down. I have a frame rate indicator from the Vision Acquisition to see at what fps the camera is acquiring images, and I also have a frame rate controller at the IMAQ AVI Create VI.
The problem is when I set the frame rate at the Create VI. The higher I set the frame rate, the fewer frames it seems to take. For example when I play the videos on Windows Media Player, at 10fps, the video length is 60s. At 100fps, the video length is 6s. At 20fps, it's 30s, and at 50fps, it's 12s. Obviously, the video length decreasing by the factor by which I increase the fps. But since higher frames per second videos show a slower/longer videos, since they have more images to display per second?
I need to be able to see a slow increase and decrease in the well deflections smoothly. At high frame rates, the video goes by so fast that I cannot analyze the deflections. At low frame rates, the video is slower, but there are too many missing frames so the deflection is not smooth (ie. you see no deflection one second, and the next, you see the peak deflection without seeing the gradual increase in deflections). It is very hard to find an "ideal" frame rate, so I was wondering if there was another way to control the frame rate such that I have high fps, and longer video lengths?
I'm attaching my VI. The bottom loop is where all the Video and Camera controls are. The top loops is to control pressure gauge and valve (just ignore that loop)
Thank you,

Hi B.J. Kim,
The problem you're seeing with the fps and video length makes sense to me. If you keep the overall frame count constant and change only the rate of playback, then the video time will be indirectly proportional, as you have noticed. Just from simple math, it appears like you kept the video image at a constant of 600 total frames while changing the frame rate between 10, 20, 30fps, etc. If you're looking to have more resolution in you video, maybe you could increase the actual frame rate of acqusition from your camera. You may also try placing a small millisecond wait in your while loop to slow down execution speed.

Poor performance / low frame rate

Hi
Well I have a scenegraph with some objects imported
from vrml files and a lot of boxes (1200 Box objects)
So when I move the view (camera) to see my model
when i pass near the boxes i have a very low frame rate
3 ,4 ,5 max.
When I don't include the boxes into my scenegraph
i get a better frame rate 15 16 17 max.This scene contains about 30 objects loaded from vrmk file.
apx. 1000 boxes are so hard to render?
they are grouped together like in a container terminal.
what can cause this?
is this scenegraph to large?
The computer is very good 2Gb DDRAM, a very good graphic card (128 Mb).
Please answer to me or give a hint
Regards
Cristian
PS. I have also noticed that when I tried the well known java3d HelloUniverse program with 1000 colored cubes it was very slow when i resized the window?
Do i do something wrong or java3d is slow ?
Thx again

Well, 1200 boxes equals 14,400 faces/polygons (2 per side of the cube) to be rendered. Plus, with the addition of the objects imported it'll be higher.
The graphics adapter may not be powerful enough to render this amount at an acceptable frame rate. Having 128MB of RAM doesn't mean it's fast.

Bootcamp Vista and Low Frame Rates

Hey Guys,
I've got a MBP Santa Rosa, and I've loaded Vista (both 32bit and x64) at varying stages onto bootcamp, and I seem to get very low frame rates. In TF2 I'm only topping out around 50 to 60 (vsync isn't on)
I've tried the official bootcamp drivers and also some from Laptopvideo2go. I'm at a bit of a loss here.
Can anyone recommend a decent driver set or at least provide some numbers on what they're getting in TF2 or the Source engine stress test?
Screen settings are at 1280x1024 with all settings at default recommendation.
Tried 3dmark06 but it runs at about 15FPS in the first test and I bail out cause I can't bare to watch it like that.

Fair point Sorry

How to get the frame rate of my application

Hi again...
How can I get the frame rate of my application?
I also want the frame rate value to be the title of the frame, updated every second. How do I do that?
thanks in advance...

To get the path where your application has been installed you have to do the following:
have a class called "what_ever" in the folder.
then you do a litte:
String path=
what_ever.class.getRessource("what_ever.class").toString()
That get you a string like:
file:/C:/Program Files/Cool_program/what_ever.class
Then you process the result a little to remove anything you don't want:
path=path.substring(path.indexOf('/')+1),path.lastIndexOf('/'))
//Might be a little error here but you should find out //quickly if it's the case
And here you go, you have a nice
C:/Program Files/Cool_program
which is the path to your application.
Hooray

Standard frame rate for 1080p NTSC?

Hello and thanks for having me! Very new(b) to Adobe Premier, so I'll throw something basic out, thanks for your advice:
the short version:
What is the 'standard' framerate for NTSC 1080p? Does this framerate differ from what you would use for output at 720p,
and would you choose different framerates depending on delivery method (web vs. bluray)?
the long version:
I have at my disposal a very capable rig to work on, and just doing some basic editing for my audio CV reel. The source material is usually 1080p and sometimes 720p, whether it be streamed into my capture card HDMI from playback sources, or full production originals which I have scored for clients.
Therefore, while editing my reel together, I'd like to work at full 1080p and downconvert for smaller formats afterword.
However, I am very new to video editing, and not sure what framerate to work in. I see the available selections of NTSC 1080p at several framerates,
and I am aware of all available framerates in the US and abroad, so my question is:
What is the standard frame rate for NTSC 1080p used for BluRay or highbandwidth web transmission? Some are telling me 'use 60, its standard'. Others tell me its 24. Still others say 24 is only for working with film, or interpolating other sources to 'make your stuff look like film'.
Thank you for any answers or resources, and have a nice evening!

For Blu-ray you can have two frame rates at 1080 resolution, 30 fps interlaced, or 24 fps progressive. 1080p/30 will not go onto a Blu-ray.
At 720 resolution, you can have 60 fps or 24 fps, both progressive.
If you want to work at 1080p, your only option is 24 fps.
Web delivery is a different matter. There are no defined standards and pretty much anything you like will play on the web.
(On a side note, drop and non-drop frame refers strictly to the timecode information, and does not regulate frame rates.)

Frame rate for FLVs in FLEX, 10, 12, or 15?

We are using Flex to create a rich internet application that
delivers a lot of video which is then synchronized with a series of
screen events. Our concern has to do with the frame rate for the
FLVs. We are shooting at 30fps and have been told that the delivery
should be a multiple of 30, hence either 10 or 15fps. But Flex is
at 24fps, so we were wondering if the FLV should be delivered at
12fps. Any advice?

you need to optimize your code/display especially if you're creating an app for a mobile device.
one of the easiest things to do is to enable the cacheAsBitmap property of most movieclips and assign a cacheAsBitmapMatrix to those movieclips that would benefit.

Are you using a wireless router to connect to the internet? if so disconnect the wireless router and connect through LAN. Ensure you disconnect all your wirless devices including a wirless dongle if you are using one. Once connected through LAN download again. This worked for me today.

How do I get sound to work for games...?

How do I get sound to work for game apps, when I have sound for other items on ipad2?

Have you got notifications muted ? Only notifications (including games) get muted, so the iPod and Videos apps, and headphones, still get sound.
Depending on what you've got Settings > General > Use Side Switch To set to (mute or rotation lock), then you can mute notifications by the switch on the right hand side of the iPad, or via the taskbar : double-click the home button; slide from the left; and it's the icon far left; press home again to exit the taskbar. The function that isn't on the side switch is set via the taskbar instead : http://support.apple.com/kb/HT4085
