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.
Up to 1920 x 1200 we can see Mafia II offers us that over 60 FPS average we want. Batman AA on the other hand gives us that 30 FPS minimum we want at all resolutions.
PhysX enabled and set to high on this kind of setup should yield more than enough frames for people. Some will probably choose to go down the AA / AF path, though, which makes the game look better and offers higher FPS still.
PhysX continues to be a bit of a mixed bag. It's not that we don't like it, it's just that we're not seeing the support for it still. At least NVIDIA are continuing to push the technology and hopefully it can gain a bit more momentum in 2011.
