Overview
- Driver 591.44 re-enables GPU‑accelerated 32‑bit PhysX on RTX 50‑series cards through custom support and is available via Nvidia’s website or app.
- Nine legacy titles are supported at launch: 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.
- Nvidia says Batman: Arkham Asylum will be added in early 2026, while broader support for the more than 40 affected games tracked by the community remains unconfirmed.
- The regression on RTX 50 GPUs stemmed from dropping 32‑bit CUDA, which forced older PhysX titles to run effects on the CPU and led to sharp frame‑rate drops in games like Borderlands 2.
- The same driver delivers Battlefield 6 Winter Offensive optimizations with Nvidia‑claimed up to 3.8x average frame‑rate gains using DLSS 4, plus DLSS Ray Reconstruction updates for Call of Duty: Black Ops 7 and a fix for Windows 11 performance slowdowns introduced by an October update.
