Here we're able to find out when PhysX is turned on in games that support it what kind of frame rates we're able to get. We always set PhysX to the highest possible in game settings while also keeping detail at its highest.
We can see with PhysX on Mafia II struggles to get to 60 FPS at all resolutions. Batman AA on the other hand doesn't have the same problem. We again see the Galaxy GTX 480 help break that 30 FPS minimum as well at the highest resolution.
