Nvidia Quietly Kills 32-bit PhysX Support on RTX 50 Series GPUs

Nvidia has silently ended support for 32-bit PhysX on its RTX 50 series GPUs. This game-specific physics technology, popular in the early 2000s, is officially retired due to the deprecation of 32-bit CUDA applications support starting with the RTX 50 series. While no 64-bit PhysX games exist, RTX 50 and later GPUs will lack PhysX support entirely. PhysX, once used in major titles like the Batman Arkham trilogy and Borderlands series, offloaded physics calculations from the CPU to the GPU for performance gains. However, its Nvidia-only nature and inflexibility led to its decline. To use PhysX on RTX 50 series cards, users must now utilize an older GPU dedicated to PhysX.
