Don't know what you're talking about, my Win7 handles everything perfectly well
every valve game crashes randomly in full screen, garrys mod included.
diablo 2 doesn't even run at all in full screen.
minecraft crashes video drivers when maximized. (please note i didn't have the same problem on vista with literally the exact same video drivers)
and more.
7 was good for about, one week before this stuff happened.
i was hoping for 8 to be good, then they announced metro.
forget.
