Can't turn on advanced physx effects?

[hh-]

This option (or whatever it's called) is turned off automatically and I can't get it to turn on. Does this require a better graphics card or something, I have a 8800 series Nvidia card and I thought it completely supported PhysX? :confused:

You need vista to activate full physX support.

You need more than Vista to run this game smoothly. Even with my build the game is still stuttering/choppy. Seriously... only 32-bit OS support? I even turned physx off on all counts and still the game stutters. Guess the game hates 64-bit OS's and quad core cpu's

Hello.
I have the same problem.
I am running Cryostasis on Windows 7 (64 bit) with a pair of 8800 GTXs and I can't turn on Advanced PhysX either.
Any suggestions as to how I get this working?

All my other PhysX games work like a charm.

:(
