I recently bought a VisionTek [ Xtasy ] Geforce Ti4200 and the fps seems to go WAY down, like in GTA3 itll go down to the 20's. On CS itll go down to 40 when there is like 5 ppl in front of me.
512 MB RAM is more than enuf for running WinXp. .But certainly the more the better... However, it doesn't make any sense for a GF4 for getting such a low fps and with such amount of RAM. Try updating your driver and post the result here. I'm also getting a GF4 Ti4200 in the upcoming weeks if I won the bet in WC2002. Cheers...
