As you already know, Nvidia has <b><a href="http://www.ngohq.com/news/16560-patch-re-enables-physx-when-ati-card-is-present.html" target="_blank">robbed its customers</a></b> by disabling the PhysX technology (GPU and PPU) anytime a Non-Nvidia GPU is present in the system (even IGPs) since the release of 186 GeForce drivers, to prevent consumers from using hybrid PhysX.

Yes, this is a bug in the latest build of PhysX that was packaged with the driver. We'll be fixing this issue ASAP - the WHQL driver launching in early June won't have this issue. <b>-NVIDIA</b>
