- The RTX 50 series GPUs drop support for 32-bit PhysX games, affecting older titles like Borderlands 2, Mirror’s Edge, and Batman: Arkham Asylum.
- Nvidia confirmed that the RTX 50 series and future releases will not support 32-bit CUDA applications.
- 64-bit PhysX applications still work on the RTX 50 series, while the RTX 40 series and older continue to support 32-bit PhysX.
The RTX 50 series is shaping to be the worst lineup in Nvidia’s GPU history. If the lack of performance and melting cases weren’t enough, the GPU has now been found to drop support for 32-bit PhysX games.
The case was first reported by a Redditor who ran a few games based on 32-bit PhysX but could not run them. The same user tried running Borderlands 2, but it ran terribly, with the framerate dropping below 60 by just standing.
Why it matters: Nvidia’s removal of support for 32-bit PhysX titles for its Blackwell series is disappointing, and users won’t be able to play legacy titles anymore.

However, Borderlands 2 could only run by forcing PhysX via the config file. This is similar to how it ran on AMD cards by forcing PhysX on the CPU back in the day.
An Nvidia Employee confirmed the lack of support, saying that the 32-bit CUDA applications are unsupported for the RTX 50 series GPU and will remain unsupported for future releases as well.
So far, games like Borderlands 2, Mirror’s Edge, Batman: Arkham Asylum and Origins, and Assassin’s Creed IV Black Flag won’t be able to run on the newer Blackwell GPUs.
On the other hand, the RTX 40 series and older will continue to support 32-bit PhysX applications. Moreover, 64-bit PhysX applications run just as fine on the RTX 50 series, according to the user who ran Batman: Arkham Knight and tested it.
So far, Nvidia has taken the first step in dropping support for legacy titles. The only workaround for now is to force PhysX on the CPU, but that comes with a considerable performance sacrifice.
