Hercules Prophet Geforce 3 on a AMD 1.2ghz, my OS is Windows XP pro. Now before I had XP installed I was running 98se and this video card gave me 125 to 75 fps steady with no problems. Ive tried the newest and even went back to some of the older drivers and this hasnt helped. I wanna say its the video card itself but before I come to that conclusion I wanna see what you guys think.
