thedare

ok so i bought the game today and have since spent all day trying to get it to work. my rig Intel Q6600 2.4 GHz quad 2GB DDR2 Ram Nvidia 8500GT (512MB) Asus P5N-MX Mobo Windows 7 x64 so i have tried installing Beta nVidia drivers and defragging. the game is unplayable even on the lowest settings and i am getting horrible lag on the menu screen. anybody know the problem? so far i am guessing it is a 64 bit thing :( i havnt tried online yet. only solo play and it is all unplayable
