Choppy Playback


On YouTube and other Flash based video sites, Flash drops a huge number of frames, making playback very choppy even with the smallest resolution (360, 480). This doesn't happen with IE, not even while using the highest resolution (720, 1080) available. I know my computer is more than powerful enough to play back full HD, even without hardware acceleration. Is this Firefox's fault or Flashes and is there anything I can do about it?

Hi Jamesc359,

Have you looked at our Youtube video troubleshooting section? There is a lot of great content in there.

Hopefully this helps!

Hello Matt, thank you for your reply. :-)

Yes I've already looked at the trouble shooting section. The problem persists in safe mode with hardware acceleration either enabled or disabled and my antivirus disabled. CPU utilization is minimal and fluctuating between 8-16 percent. GPU utilization is virtually non-existent. An easy Gig of RAM is free. There's no HDD activity, or any other activity that should cause problems.

While playing videos, I have noticed a choppy audio playback/echo since yesterday.

When web pages have embedded video, the video gets broken up when scrolling up or down the page. Really annoying, IE does not do it.

Try to disable hardware acceleration.
