however, in crapper games i get full fps from me gpu, like 1000 in tfc /hl1/cs.. any ideas why its not working ive installed /uninstalled gpu drivers

nVidia had some problematic 91.xx drivers. If you haven’t tried some various drivers, you might want to do so. Also, you may give the Omega Drivers a shot.
