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.
Getting into PhysX tests, we see some good gains, but not those 100% ones that have shown their face as we've gone along. Our Mafia II numbers are good, though, and really are absolute borderline playable at 1920 x 1200. Not quite the same issue for Batman AA, though, which performs strong.
