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 ?
Since you are using an AMD card, PhysX will be automatically set to "Low" and it will put the minimal PhysX load on your CPU, so nothing to worry about GPU related here. Ambient Occlusion and the AMD 6 series cards don't work together very well. You're better off leaving the option disabled.
Mouse smoothing does just that. It smooths the motion of the mouse. It should not be turned on unless you are using a very old "ball in socket" type mouse. The best thing to do is to keep it off and just adjust the mouse sensitivity to your preference.
