Ok here is the thing. I just bought a brand new gts250 ilde around 42c and never above 66c even when furmarking so here is the thing I ran windows xp for about a day and decided to upgrade to win7 trial. I caught a virus the same day i installed my graphics card. so before i had installed it i was playing call of duty world at ware and never dip below 55 fps at all... after installing windows 7 im getting 25 fps ingame. I updated directly off of nvida for win7 driver. i uesd the driver off of the cd that came with the computer for windows x before reformatting. When playing halo combat evolved i get 60 fps but when strafing i get 20 even if nobody else is on the serveer. i have 4gb of ram a e1200 and like i said using the latest drivers. I was wondering is this a common thing for 64 bit windows 7 and will 32 bit have better perforance? sheesh I know nothing is wrong with my hardware.
