Reversing a controversial architectural decision, Nvidia has released a driver that restores hardware PhysX support for RTX 50-series owners. Game Ready Driver 591.44 re-enables GPU acceleration for nine legacy titles, including Borderlands 2 and Mirror’s Edge, which had been broken since the Blackwell launch in January.
Instead of fully reinstating 32-bit CUDA (Compute Unified Device Architecture) support, the update applies a “custom support” whitelist to bypass the technical limitations of the new cards. Additionally, the software prepares systems for Battlefield 6‘s “Winter Offensive” update, promising significant frame rate gains via DLSS (Deep Learning Super Sampling) 4.
A Targeted Fix for Legacy Titles
Nvidia released GeForce Game Ready Driver 591.44 today, specifically addressing the loss of hardware acceleration in older titles. Release 591.44 follows months of user complaints regarding poor performance in classic games on top-tier hardware. Addressing the reversal in strategy, the company acknowledged the friction caused by the initial architectural shift.
“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,” stated the official Nvidia blog post.
Functioning as a whitelist rather than a broad reinstatement of 32-bit CUDA support, the solution ensures titles not on the list remain unaccelerated. The official driver announcement details exactly which games will now utilize the GPU for physics calculations rather than falling back to the CPU.
“By installing our new GeForce Game Ready Driver, the full GPU-accelerated PhysX experience can now be enjoyed in: Alice: Madness Returns, Assassin’s Creed IV: Black Flag, Batman: Arkham City, Batman: Arkham Origins, Borderlands 2, Mafia II, Metro 2033, Metro: Last Light, Mirror’s Edge”
PROMO
While most of the high-profile omissions have been addressed, one notable exception remains. Batman: Arkham Asylum, the first entry in the celebrated series, requires additional development time before it can run correctly on the new architecture.
“Support for Batman: Arkham Asylum is planned to be added in the first part of 2026,” Nvidia confirmed.
The Blackwell Architecture Bottleneck
Issues originated with the January 2025 launch of the RTX 50-series (Blackwell), which physically deprecated 32-bit CUDA cores to save die space. By deprecating these cores, the hardware change broke compatibility with the PhysX middleware used extensively in the late 2000s and early 2010s.
Nvidia’s PhysX technology played an important role in the visual effects and physics of older games such as Borderlands 2 and Mirror’s Edge. However, when Nvidia introduced its newer RTX 50-series graphics cards, PhysX wasn’t included at first. That’s because these new GPUs no longer support 32-bit CUDA, the older software foundation that PhysX relied on, so Nvidia initially left the feature out of the package.
Without GPU acceleration, physics calculations in these titles were forced onto the CPU. Even high-end modern processors struggled to handle the specific instruction sets used by the aging PhysX engine, causing frame rates to plummet in scenes with heavy particle effects or debris.
Community tracking suggests over 40 titles were affected by the deprecation, meaning this driver only repairs about 25% of the broken library. Niche titles like Cryostasis or Sacred 2 likely remain in a broken state unless Nvidia expands the whitelist in future updates.
Nvidia has previously issued post-launch corrections for the Blackwell platform. Shortly after the release of the mainstream cards, Hotfix 576.26 was deployed to address widespread stability issues and display bugs, indicating a complex maturation process for the new architecture.
Battlefield 6: Pushing the Other End of the Spectrum
Beyond retro support, the driver prepares systems for the December 9 “Winter Offensive” update for Battlefield 6. Introducing a new map, “Ice Lock,” and significant audio overhauls, the patch’s primary focus for RTX owners is the integration of the latest upscaling technologies.
According to Nvidia’s official release notes, when you play Battlefield 6 at 4K resolution with everything set to Ultra quality, turning on DLSS 4 makes a huge difference to performance.
By combining Multi Frame Generation (which creates extra frames using AI) with DLSS Super Resolution (which upscales the image intelligently), the game’s frame rate on GeForce RTX 50-series cards is boosted by roughly 3.8 times compared to running it without DLSS. In practical terms, that means on powerful desktop systems the game can reach up to around 460 frames per second, even at such demanding settings.
Achieving these frame rates requires the use of DLSS 4 and Multi-Frame Generation, features that insert AI-generated frames between traditionally rendered ones. While this boosts the visual fluidity, it does not reduce input latency to the same degree as raw rendering.
Independent testing has verified the scale of these performance uplifts, though results vary based on the specific resolution and quality settings employed.
“Given the massive leap in average frame rate and 1% lows, it’s well worth deploying both DLSS super resolution and multi-frame generation in Battlefield 6’s multiplayer game,” noted Niall Walsh, Hardware Writer at PCGamesN.
