Nvidia has quietly dropped support for 32-bit PhysX on its new RTX 50-series, affecting games that heavily rely on the physics engine. This change means some older titles will lose part of their dynamic effects, such as cloth textures and particle simulations.
Nvidia staff confirmed the move, stating that 32-bit CUDA applications are deprecated on GeForce RTX 50 series GPUs. As a result, games like Batman: Arkham City, Mirror’s Edge, and Mafia II may see reduced performance or lose specific features.
Users have found workarounds by disabling PhysX in affected games or using secondary PhysX-supported cards. However, the community is now left to find alternative solutions as official support ends.
This move marks a significant change for Nvidia, with 32-bit applications already facing deprecation on newer GPUs. The phasing out of this technology may impact niche implementations and performance, but users can still explore workarounds to maintain gameplay experience.
