If I go to this site:
...and watch this video in full screen, I basically get a slideshow, the framerate is about 1 picture a second. (non of the videos work in full screen)
Same with this Flash player:
If I leave it small it runs normally, but full screen is unusable.
Other Flash players work fine (e.g. youtube).
CPU is at about 30% when in full screen, so no problem there.
What's wrong with my system, what could be the problem? Any Ideas?
