NVIDIA Restores PhysX Support for Select 32-Bit Games on GeForce RTX 50-Series GPUs

In early 2025, NVIDIA discontinued support for 32-bit software on its GeForce RTX 50-series “Blackwell” GPUs, which led to the end of PhysX support. However, the company is making exceptions for certain games to ensure they maintain performance and stability. Due to popular demand, the following titles will continue to run smoothly: Alice: Madness Returns, Assassin’s Creed IV: Black Flag, Batman: Arkham City, Batman: Arkham Origins, Borderlands 2, Mafia II, Metro 2033, Metro: Last Light, and Mirror’s Edge. With the latest GeForce Game Ready 591.44 WHQL driver, these games will be able to fully utilize RTX 50-series performance.

Earlier, the removal of 32-bit support was quietly acknowledged as NVIDIA’s latest GeForce RTX 50 series GPUs transition away from 32-bit CUDA software, gradually shifting the gaming industry entirely to 64-bit software. While older NVIDIA GPUs from the Maxwell to Ada generations will continue to support 32-bit CUDA, NVIDIA’s earlier update disrupted backward compatibility for physics acceleration in legacy PC games on new GPUs. Users playing these titles on RTX 50 series cards had to rely on CPU-based PhysX processing, which could result in less optimal performance compared to previous GPU generations. Thankfully, performance is now back in check as 32-bit exceptions start rolling in.

PhysX began as the NovodeX engine, which Ageia acquired and rebranded in 2004, and NVIDIA later absorbed when it bought Ageia in 2008. The SDK was built to move…
