I am running an e4300 overclocked to 3 GHz and an 8800 GTS.  I have not gotten a FPS number yet but for me the game plays very smooth.  At first things were a little bit stuttery and ironically the cutscenes were the worst.  I went through the .ini file and disabled bloom.  I also created an Nvidia profile for the game and minimized AA and AF.  I am sure that the game is not AS pretty as it was before that but I cannot see the difference and the whole thing is silky smooth now.

Very happy with the game so far.  I hope to get much more MP in. 

If you want to add me in game it's: Mauxe

Which ini file do you have to adjust to change the bloom? What is bloom anyway?

now that is a fact, not sure if anyother fps will be able to beat it.
