For some reason, when i play the timedemo in doom3 at 1280x1024 with FSAA 8x/16x, the frame rate turns out to be less then 10. I have a 6800gt OCed to 380/1100 and a P4 cpu OCed from 3.0 to 3.7ghz. All other games run fine, and my 3Dmark05 score is around 5000. Doom3 is the only problem here. Any suggestions...? Thank you!
