Glossary:PhysX
From PCGamingWiki, the wiki about fixing PC games
Revision as of 18:52, 17 February 2023 by Mirh (talk | contribs) (Very much reworded the key points, to hint that GPUs accelerate *already existing* advanced effects (i.e. they aren't specifically targetting CUDA). Turns out physx 2.8.4 (also checked the SDK) still has the enableLocalPhysXCore code. Simplified some wording (thanks notes!))

Middleware used by many games for physics effects.
Key points
- Selected titles may support special additional features like extra particles (dust, smoke, debris) or advanced cloth simulation.
- They aren't technically conditional on hardware acceleration,[Note 1] but that is usually required to achieve a playable framerate.
- List of games that support Nvidia PhysX
Latest version
- These provide the PhysX runtime necessary for every pre-2.8.4 game, and the occasional title-specific update for those afterwards[2]
There are two releases of the PhysX driver that should be installed:
- NVIDIA PhysX System Software for games built on any runtime version that supports GPU acceleration[Note 2]
- PhysX Legacy System Software for all the others, generally found up to ~2008 (using version 2.7.2 or before 2.7.1)
If you are using an Nvidia graphics card the first package may be already included with the drivers.
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.

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 (or since 372.70, if any monitor is reported attached to it[3]).
- Windows 7 or Windows XP/Windows 2003 are required (Windows Vista will not work)

Issues fixed

Install latest versions of the PhysX System Software |
