Has anyone tried the UT3 PhysX levels with these drivers? I have tried multiple reinstalls of drivers, the game (and relevant patches), and the mod pack, and none of the PhysX enabled maps will work. They load, but performance, compared to pre 180.42/.43 drivers makes me think hardware PhysX is not initializing. The hail stones do not show up or bounce aropund on the ground in Heat Ray, and when PhysX intensive calculations start up in any of the levels, the fps goes down, down, down.... I do have the "Hardware PhysX" box checked in the game, and I have PhysX enabled in the nvidia control panel... I even went through the whole process of replacing PhysX files in the UT3 folder with those in the driver (which I never had to do to get it working before), and still no joy... Any suggestions?
