PhysX
PhysX cover

Key points

Used by many games for physics effects.
Hardware processing and some physics effects are restricted to Nvidia graphics cards.

Latest version

For recent games install the NVIDIA PhysX System Software. For older games (2007 and earlier) install the NVIDIA PhysX Legacy System Software.

If you are using an Nvidia graphics card some PhysX versions are already included.

PhysX v2.5.2 compatibility

The NVIDIA PhysX Legacy System Software does not include v2.5.2; this is known to affect Infernal and The Void but there may be other affected games.
Instructions

Secondary PhysX card with an AMD/ATI video card

Nvidia only allows a secondary Nvidia card to be used for PhysX if the primary card is also an Nvidia card.

Requirements

  • Windows 7 or Windows XP/Windows 2003 (Windows Vista will not work)
  • AMD/ATI GPU used for your primary display
  • NVIDIA GPU that can support Hardware PhysX (series 8 and newer, with a minimum of 32 cores and 25 6 MB of video memory)

Installation steps

Instructions

Notes

  1. If you update PhysX System Software after using the mod, you should use it again to patch the updated PhysX files.
  2. It is safe to use the mod several times - all needed files will be patched only once.
  3. If you still have problems with fake displays and desktop extension, try to delete a fake display and create it again.
  4. To let the mod correctly patch all needed files on x64 versions of Windows XP/Windows 2003, install KB942589 hotfix first.

Issues fixed
