The best results for me have been to use the *** 11.8 Drivers***. The "new" drivers and performance release drivers have completely stalled the game. I can now run everything to max with the patch on an AMD Phenom II 555 3.2 OC'd to 4.22 Ghz (1.44volts) with 16 GB 1333 memory and XFX 6950 HD 1 GB 830hz/1300hz video card...40-50fps.
