PhysX quietly retired on RTX 50 series GPUs: Nvidia ends 32-bit CUDA app support | Tom's Hardware
PhysX is a proprietary physics simulation SDK that handles ragdolls, cloth simulation, particles, volumetric fluid simulation, and other physics-specific graphic effects. It was originally announced with the claim that physics calculations would be performed on the GPU (formerly the Ageia PPU) instead of the CPU, which promised faster frame rates and better quality physics effects than what could be achieved on the CPU. The problem was that PhysX was only possible on NVIDIA GPUs because of the use of CUDA.
On January 17, 2025, NVIDIA will remove 32-bit native and cross-compilation from the CUDA 12.0 and later toolkits, ending support for developing and debugging 32-bit CUDA applications.
With the end of support for PhysX, games that use PhysX, such as 'Borderlands 2,' 'Metro Exodus,' and 'The Witcher 3: Wild Hunt,' will experience reduced performance on the RTX 50 series.
According to technology media Tom's Hardware, PhysX required NVIDIA GPUs, making it difficult to use on competing GPUs, consoles, and smartphones. This led to a significant decline in PhysX adoption in the late 2010s, and it began to decline when NVIDIA began to drop support for some PhysX features.
Tom's Hardware reported that 'as far as we know, there are no 64-bit games that integrate PhysX technology, so this effectively puts PhysX to rest.'
