I can, easily.
The new Nvidia driver 314.07 improved my performance.
And it seems my GTX670 is not magical :

Even a GTX580 can run the game at 60fps with Physx high, I was already very close to that with my GTX570.
Same goes for Batman AA/AC and Alice Madness Returns. Haven't tried Hawken yet.
(Except for the Penguin fight with the Mr. Freeze gun, I drop to the 50's when there are a bunch of ice particles being rendered)
