If you don't feel like reading, you can view the video tutorial at the following URL.

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...

  • Uninstall Nvidia PhysX (since we're rolling back drivers)
  • Install the Ageia PhysX Driver
  • Now go to C:\Program Files\AGEIA Technologies (or C:\Program Files (x86)\AGEIA Technologies if you're using a 64 bit system.)
  • Copy the bin folder
  • Create a new folder elsewhere (I put it on a separate hard drive) on your system
  • Rename the new folder AGEIA Technologies
  • Paste the bin folder under the new AGEIA Technologies you just created

Note: the bin folder contains demos and an application extension which allows you to play older Ageia PhysX games like Switchball and Stoked Rider.


  • Now install the Nvidia PhysX 8.09.04 drivers
  • After installing, return to C:\Program Files\AGEIA Technologies
  • Copy everything under AGEIA Technologies
  • Paste the copied files under your created folder, AGEIA Technologies
  • Go to C:\Windows\System32 (and/or C:\Windows\SysWOW64 if you're using 64 bit).
  • Sort everything by name.
  • Scroll down to P and find anything starting with the word PhysX.
  • Copy those files with the word "PhysX" in it's name.
  • Return to the folder you created, AGEIA Technologies
  • Create a new folder under the copied AGEIA Technologies.
  • Rename the folder Windows.
  • Enter the new Windows folder and create a new folder.
  • Rename the new folder System32.
  • If you're using 64bit, create another folder here and rename it SysWOW64
  • Paste the files you copied into the System32 folder you created.

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.


  • Now return to C:\Windows\System32.
  • Enter the drivers folder.
  • Sort files by name and scroll down under the names beginning with P.
  • Copy a PhysX.sys related file. (physX64.sys on 64bit)
  • Return to AGEIA Technologies\Windows\System32 and create a new folder.
  • Rename the new folder drivers.
  • Paste the file in drivers.
  • Now return to C:\Windows\System32 (or C:\Windows\SysWOW64 for 64 bit)
  • Find the AGEIA folder and copy it.
  • Return to AGEIA Technologies\Windows and paste it in the folder you pulled it from.
  • Now install the newest Nvidia PhysX Drivers; 9.10.0513 or higher.
  • After the installation has finished, find C:\Program Files\NVIDIA Corporation\PhysX\Engine. (C:\Program Files (x86)\NVIDIA Corporation\PhysX\Engine for 64bit.)
  • Copy all contents of the Engine folder
  • Create a new folder and name it Backup, now paste all contents inside Backup.

The backup folder will be used to restore selective PhysX engines, depending on the games you play.


  • Now copy all contents of the AGEIA Technologies folder you created, spare for the Windows folder.
  • Return to C:\Program Files\NVIDIA Corporation\PhysX\Engine. (C:\Program Files (x86)\NVIDIA Corporation\PhysX\Engine for 64bit.)
  • Paste the copied contents of AGEIA Technologies to the Engine folder, overwrite when prompted.
  • Now return to the AGEIA Technologies\Windows folder you created.
  • Copy the contents, minus the registry entry.
  • Paste them under C:\Windows, say yes when prompted to overwrite.

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!
