Nvidia just delivered what gamers have been demanding since the RTX 50-series launch - PhysX support is back. The new Game Ready driver 591.44 restores GPU acceleration for nine popular PhysX games including Borderlands 2 and Mirror's Edge, after the company initially dropped the feature due to 32-bit CUDA compatibility issues. Community pressure worked, but don't expect every affected game to get the fix.
Nvidia is making good on community demands today, rolling out a driver update that brings PhysX GPU acceleration back to its RTX 50-series graphics cards. The move comes after months of frustrated feedback from gamers who found their favorite older titles suddenly running like molasses on the company's latest hardware.
The drama started when Nvidia launched the RTX 50-series earlier this year without PhysX support, breaking GPU acceleration for dozens of games that relied on the physics simulation technology. Titles like Borderlands 2 and Mirror's Edge, which used PhysX for realistic glass shattering, fluid dynamics, and particle effects, suddenly found themselves dumping all that computational work onto the CPU instead.
"We heard the feedback from the community, and with the launch of our new driver today, we are adding custom support for GeForce gamers' most played PhysX-accelerated games," Nvidia said in their official announcement. The company emphasized they're "enabling full performance on GeForce RTX 50 Series GPUs, in line with our existing PhysX support on prior-generation GPUs."
The technical culprit behind this mess was Nvidia's decision to drop 32-bit CUDA support from the RTX 50-series architecture. While that made sense for streamlining their modern GPU design, it created a compatibility nightmare for older PhysX-enabled games that were built around 32-bit foundations. Games like Borderlands 2 saw frame rates plummet below 60fps as the CPU struggled to handle physics calculations that GPUs used to breeze through.
Nvidia's solution involves what they're calling "custom support" - essentially hand-crafted fixes for specific high-profile titles. The current supported game list covers nine titles: 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.
But here's where it gets tricky for gamers with deeper libraries. According to tracking by Resetera forum members, more than 40 games have been affected by the PhysX removal. Nvidia's commitment to support Batman: Arkham Asylum "in the first part of 2026" suggests they're taking a very selective approach to these fixes.
