NVIDIA officially launched GPU acceleration for PhysX when they released
the PhysX driver version 8.06.12 which enables PhysX acceleration for the following cards :
GeForce GTX 280
GeForce GTX 260
GeForce 9800 GTX+
GeForce 9800 GTX
You will need to install the latest 177.39 ForceWare driver in addition to the PhysX driver.
At this moment PhysX support has only been enabled for those four GPUs. NVIDIA will progressively
enable PhysX support in the other GeForce 9 and GeForce 8 graphics over the next few weeks.
