    Major bug in flash 10.2/10.3 beta. FPS drop in 1080p, HA.


      Not sure if it has been reported before but there's a huge bug in the hardware acceleration on flash 10.2 and 10.3 beta.


      The issue:
      If you run 1080p youtube content fullscreen, hardware acceleration on, the FPS drop to 30-80% of what it should be, AFTER you seek in the video and flip back and forth fullscreen mode (if you don't do that, it just runs fine). If the FPS doesn't drop, then just flip/back fullscreen some more and seek some more, it pretty soon will drop. Once it dropped, it will stay low for the rest of the movie.


      It's easy to verify when you put the FPS counter ('show video info') on screen, but you can also see it by just closely watching the video and see how it becomes less smooth.


      When you disable the hardware acceleration the issue is gone.


      Tested and confirmed on:

      Win7, winXP

      Chrome, IE, Mozilla

      Flash 10.2 and 10.3 beta

      Nvidia, ATI (both latest drivers)


      So. pretty much everybody suffers from it I guess ...
