It seems that owners of AGEIA PhysX Processors are out of luck. A user by the name of 666 from PhysXInfo
received the following email from Nvidia:
"The current PhysX driver unfortunately does not support Aegia PPU hardware which you're already aware. Support for Aegia PPU ended after the 8.xx.xx driver but like you we've receive other users asking to include support in current PhysX releases. There are discussions to release a stand-along PhysX driver that will support Aegia PPU but that is still in discussion and I'm unable to get any confirmation or schedule. I can certainly update you if this changes or you can check back with us in a couple of months. Unfortunately we don't know anymore at this point."
