I have a geforce 2 ultra on Win2k Professional. When I play counter-strike, everything is smooth, but when i suddenly turn or jump, half of a texture of a box, or character starts missings and becomes jagged. Also when I jump and go fast, its not smooth. I have done the clock tweaking already, and turned on Antiliasing to the highest. Also, should anistropic filtering be turned on (i have it turned on). THanks for the help!
