Yes, I do believe that my fps is not terribly bad... Most of the time I have 60fps... it's just that IF I put AO on and face vistas, it drops to 30fps...
Now, what I would like to know is, how much of a performance hit do you think physx has ?? I don't know much about physx... is it compatible with radeon cards ? or just nvidia?
And if it does work with readon cards, do I need to manually download physx software onto my pc and configure it properly for my radeon card?
also, do you have any idea why is it that the AO eats so much FPS when I face vistas in the game ??
EDIT: What does "mouse smoothing" do ?
