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.
Batman performance is boosted across the board and we see a 30 FPS minimum again at all resolutions. Mafia II performance is also boosted, but does fall shy of that 60 FPS average we want. You can see we're right on the edge of it, though.
