looking for geniuses to solve this riddle.

post #1 of 114
Thread Starter 
Cuz I sure can't.
Very weird situation. So please read on to understand situation I am having.

First, system specs.

Windows7 32bit
sempron 140 single core athlon
biostar 880g
gt 430
4 gigs ram.
46 inch 1080p sony bavaria
P95 stable.

Everything is updated as of 2 days ago. Includes bios ,mobo, video card drivers, windows updates, flash player updates, dx 9 .

OK now to the problem.

Case 1:
When I go on youtube and play any 1080p clip, cpu utilization consistently hits 90s and and even as high as 100. Video play back is complete *****. Stutters choppiness everywhere.

Case 2:
I pause the video, let the entire clip buffer up, wait 5 minutes after its fully buffered to be sure its fully buffered, resume play, and cpu utilization consistently hits high 90s, 100s. Video playback is again, complete *****.

Case 3:
I play the video through, choppy mess, 100% cpu utilization, then I rewind it to the beginning.
I get flawless play, cpu utilization 40-70%.

Case 4:
I pause the video, let it buffer about half way, start playing, high 90s% utilization chopfest, then quickly I rewind it a little bit, and utilization tops off at high 80s, hits 90 occasionally, but overall plays it quite well.

What the heck?

Even on my quad core I have no luck playing HD video on youtube, this is normal.

You might have better luck using Chrome, it uses GPU acceleration.

Something is wrong with the codec and GPU off-loading.

Can you download the YouTube clips and play them locally?

IE9 and Firefox 4.0 both support hardware acceleration as well.

Yah I dont think this is a hardware issue. Maybe its the browser being a resource hog while buffering?
What browser are you using?
post #6 of 114
First, are you using a browser that has GPU Acceleration?

Second, have you tried unlocking your CPU to an X2? I believe it may unlock to a X2 7750 BE, which would be quite the blessing. Have you overclocked the CPU at all?

Basically enable hardware acceleration in flash and other codecs, make sure your using IE9 or Firefox 4 for GPU acceleration.

If neither of them work it could be Energy saving stuff enabled on the CPU causing it to throttle...

Yes, it played perfectly,cpu utilization maxed out around 25%.

I have been testing with chrome, firefox, ie9 all with same results. I even had firefox use memory as browser cache.

Buffering is not the complete issue here, because if I let a video completely buffer while paused, then start play, its still choppy. I have to rewind it slightly to get it to run with lower cpu utilization.

How do I make sure that hardware acceleration is on?

Should I download a codec pac or something as well?
