My problem is that, when i run a fullscreen game on my main screen and will see a movie or something else on my other screen, the video on that screen lags alot, i tryed with Flash Player, vlc and WMP, they all do it same.
It looks like windows 8 go into a baggrund mode where it save performance, to the program that is in fullscreen, i did not have this issus with the first release of windows 8.

Anyone else have this problem?, and maybe a fix.
