Well I bought a ati x1800gto recently for about 60$ new and I was running XP. When I played Counter strike source on xp at 1200x1024 and got a avg frame rate of 95 then when I switched to windows vista ultimate I noticed that at 1200x960 res and the same settings I got a avg frame rate of about 60. I dont think its because of the vista ati drivers but Its a shot in the dark. I have the latest drivers for vista. I also just got another gig of ram from 1 gig to 2 gigs to accommodate vista and its still 60 fps. Does anyone know why or is it really because of the drivers. I dont think it is because I dont think vista can have a difference of 35 fps. I want to fix this problem really quick because I am about to get a 22" widescreen LCD monitor in the mail a big bump from my 17" CRT that only supports a 1200x1024 max resolution and I would like to play a at much higher resolution with my new LCD monitor because it supports up to 1600x1200 res.Any help would be much appreciated.
