Hi, I'm experiencing jerky playback on all youtube videos. The sound has no problems but the video has these "micro" jerks. I have compared same videos between Chrome and Firefox and on Chrome the videos work fluidly but on Firefox not so much. I've tried turning off hardware acceleration on firefox, on flash and on both but nothing seems to help. While watching videos on youtube in 1080p firefox cpu usage is less than 5% and flashplayer's around 1-15%, gpu usage is 0.

If you have problems with current Shockwave Flash plugin versions then check this:

  • see if there are updates for your graphics drive drivers

  • disable protected mode in the Flash plugin (Flash 11.3+ on Windows Vista and later)

I'm using newest graphics driver from AMD. Changing to protected mode = 0 didn't help. I have tried turning HW acceleration off and that didn't help either.

Also this happens on a clean install of windows 7 with only the necessary drivers installed.
