If you're reading this, then you have an Ageia PhysX card and your frustrated with Nvidia for abandoning THE Relic of Dedicated Physics Processors with their latest PhysX drivers.However, there is something you can do to fix that and restore support to that PPU,
and all it requires is a little copy/paste and some registry editing.
I'll be going through, step by step, what specifically you need to do to
restore PPU support with the latest PhysX drivers for both 32 and 64 bit systems.You will need 3 things to start with:1) An old Ageia PhysX System Software (doesn't matter which one, as long as it's AGEIA. You can Google it or look for it on PhysXFiles)2) Nvidia PhysX System Software 8.09.04 (which can be picked up from the Nvidia website)3) Newest Nvidia PhysX System Software (9.10.0513 or higher)
Once you have all three downloaded and ready, you can begin...
bin folder contains demos and an application extension which allows you
to play older Ageia PhysX games like Switchball and Stoked Rider.
Note: When using 64bit be sure to differentiate the files you copied between System32 and SysWOW64, so anything from C:\Windows\System32 will go into the AGEIA Technologies\Windows\System32 folder you created, and anything from C:\Windows\SysWOW64 will go into the AGEIA Technologies\Windows\SysWOW64 folder you created.
The backup folder will be used to restore selective PhysX engines, depending on the games you play.
At this point you are officially done, all that needs to be done now is the configuration of your PhysX settings by opening C:\Windows\System32\PhysXCplUI.exe (or C:\Windows\SysWOW64\PhysXCplUI.exe for 64 bit).Depending
on which games you play and what kind of hardware acceleration you want
them to use, you can use the backup folder to restore GPU support to
certain games that use a selective type of engine. For example,
say you think Cryostasis runs too slow off the PPU. You enter the
Cryostasis system folder and find in the details of NxCooking.dll that
it uses the v2.7.3 Engine. So restore the v2.7.3 folder from the C:\Program Files\NVIDIA Corporation\PhysX\Engine\Backup folder.Even if you do have a dedicated GPU for PhysX, go ahead and set the Hardware Device Selection to AGEIA PhysX, the GPU will still engage with GPU heavy PhysX games and the Ageia PhysX card will only engage for PPU and CPU PhysX games.Now there are some games that can use either a GPU or PPU for PhysX (Mirror's Edge, UT3, GRAW2); these games will use the GPU by default. If you want the PPU
to be used for these games, open the Nvidia Control Panel and go to
Manage 3D Settings. Go to the Program Settings tab and look for those
specific games that can use either PhysX accelerator. Once you found the specific game, scroll down under feature, to "CUDA - GPUs" and disable all other GPUs besides the main Video Card.After following these steps, you now can play every PhysX game in history, with out having the need to uninstall and reinstall PhysX drivers.Certainly hope this helps for all you PPU
owners out there. If something didn't work or wasn't clear, let me
know.Have fun and get GAMING!http://www.youtube.com/watch?v=yEl6c-hHid0
