Anyway, I have a Dell XPS 420 with a quad core, 4 gigs of ram, and an ATI radeon HD 2400 Pro, and I'm running Vista I think 32 bit.. when I try to play a game like Crysis, it just is really slow and laggy. I know Crysis takes crazy computers to play well, but I thought mine would be able to handle it with the quad core and 4 gigs of ram. Any help to help my PC play higher quality games?? I think I have updated drivers, but not sure. Could that be the problem? Anyway, thanks in advance.
