Since the Nvidia PhysX 8.06.12 driver had been installed, people have found it impossible to turn off the GPU PhysX or switch it to CPU. NV PhysX Tweaker 1.0 will allow you to enable or diasble the PhysX driver over the GPU or CPU without uninstalling the PhysX driver.

Windows Vista 32-bit, GeForce G80/G92/GT200 and NV PhysX drivers are required.
