Hello,

Have tried to run a basic PhysX project on older PC's but had some problems.

Is it possible to run games with PhysX on older machines?

Tried to run a basic demo with PhysX on a GeForce 4 Ti4200 but no luck to launch it.
It starts the game (you can even see the first scene) but then it crashes.
(Installed all drivers & software)

Yes, PhysX seems to run on very old machines. I have a Compaq computer from 2002 with onboard Intel graphics and the new car demo runs fine on it, although without shadows.
