This game doesn't require a GeForce 4 Ti4600 to play, just a plan old GeForce 2. "Optimized for GeForce2 graphics, weapon effects ? from real Army weapons such as the M16A2 assault rifle and M24 sniper rifle ? offer another layer of realism. Tracers zip by as machine gun fire barely misses, shell casings ping off the ground around you as you return fire, wood splinters and glass shards rain from the wall behind as bullets tear out chunks ? this isn?t like any ?free? game you?ve seen before." -nvidia.com
