Where are all the Physx shown in the tech demo???

I'm running Cryostasis n XP and I suspect that some of Phys X effects are shader model 4 only so I'm only seeing 'some' of the Phys X stuff. I may be wrong though. Are you using Vista?

Also, I've decided to put the game to rest until a patch of some description is released. I can't run the game without rolling back to the Phys X version included on the Cryostasis DVD - sorry can't remember the number but it's a version from late 2008. if I run any other Phys X software I get a runtime error when starting the game.

I've also noticed that performance drops through the floor for no apparent reason at certain times. If I quit back to Windows and restart the game perfomance suddenly shoots up again and it becomes playable once more. For instance when I was stood in a cell staring at a wall my framerate dropped into single digits. I quit and reloaded then I'm back into the mid 30's again.
