As you are certainly aware, a playable demo version of the upcoming game Mafia2, featuring NVIDIA PhysX, was released yesterday. Because of unexpected issues with the installer of the PhysX System Software (v 9.10.0512), GPU accelerated PhysX was not working on some systems, resulting in PhysX only running on the CPU at lower framerates. NVIDIA have now posted an updated PhysX System Software which fixes these problems.
2K is also working on an auto-update patch for the demo, which comes via Steam and which should be available shortly too.
