You don't have to have 2GB to be able to play FEAR...I can max out settings with soft shadows and some AA and AF enabled and my framerate is still fine, this being only with 1GB...of course memory is really what holds this games full potential back but that's simply because it isn't optimized wellWell how am I supposed to overclock and play F.E.A.R then?
Besides that...good luck playing FEAR on a GeForce4
