Earlier this year, Nvidia quietly dropped support for 32-bit CUDA applications in its drivers for GeForce RTX 50-series graphics cards. While the move had been long planned and not unexpected, the change did have one disappointing outcome: every game that used 32-bit PhysX libraries for visual effects would be forced to either disable it or process them on the CPU. Well, not any more, as Nvidia has had a change of heart and it’s back again in the latest driver set.
However, it is worth noting that the new Game Ready Driver 591.44 drivers won’t suddenly run every 32-bit CUDA program, as Nvidia has only added support for certain games. Fortunately, it seems to be all the popular ones that were badly affected by the CUDA change, as detailed in the relevant driver blog. The full list of revitalised games is:
- 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
Batman: Arkham Asylum will eventually join the others, but not until “the first part of 2026”. Your guess is as good as mine as to just when that exactly is. For every other game that’s not on the list, you’ll need to either go down a dual-GPU route (i.e. use an older Nvidia GPU in a second PCIe slot and use the Nvidia Control Panel to force PhysX to be processed on that one) or just accept the wonky performance.
At the risk of fueling some flames, I tried Borderlands 2 with the new 591.44 drivers…
