Having performance issues??? Time to check your settings
 

Please review these recommendations if you are still having performance issues with the lastest beta patch.
I have double checked my findings with another set of tests on 3 different lower spec machines I have and the conclusion is the same.

Additional testing was done on
i7 Laptop with GT330M 8GB Ram

Intel Core2Duo 6600 8GB Ram
and
Intel i7 950 8GB Ram
with the following video card combinations

Nvidia 8800 Ultra 768MB card (just under minimum spec)
single 4870X2, + 4870x2 x 2 1GB cards (quadfire)
single 5870, 5970 and Quadfire 5870 1GB cards
GTX580 1.5GB cards single and SLI

Though the FPS varied between the various cards the stutters were consistently removed by dropping to the settings recommended in my testing.
When the newest patch comes out I will repeat my findings with more test data for all combinations.
