Flash video limiting your GPU clock to 2d values?

[Ilean]

My 5870 is having similar issues. I believe it's endemic to the current crop of ATI cards.

Not sure if the 6XXX series is better at this or not.

Getting accelerating decoding and software rendering cancels the problem. Go fullscreen and it will be ok until you skip to another part of the video which turns accelerated rendering on and lowers gpu clocks back.
