Odd.. I have a 3D Prophet 32meg DDR running 5.31 drivers and I don't have any problems with AH. I play at 1600x1200.
Blur, I get better FPS using the 5.xx drivers instead of the 3.xx, too bad your having problems with the newer drivers.
Mighty1 & Blur: do you guys have your desktop set to 1600x1200? If so what refresh are you using? I believe mine is still set for 1600x1200 at 80hz.
