NVIDIA Restores 32bit PhysX Support on Blackwell 50 Series GPUs

Many older PC games with great physics effects were hurt when Nvidia's 50-series GPUs launched without 32-bit PhysX support. As a result, physics calculations were performed by the CPU, resulting in much lower frame rates that varied depending on the user's processor.

At the time, it was unclear how this limitation would be addressed, and expectations were low given the age of the affected titles.

32-bit PhysX support is now back for the Blackwell architecture.

Nvidia has restored support for a curated list of games using a technique that has not yet been fully explained. The confirmed titles include Alice: Madness Returns, Assassin's Creed IV: Black Flag, the Batman games, Borderlands 2, Mafia 2, Metro 2033, Metro: Last Light, and Mirror's Edge.

There are also plans to add Batman: Arkham Asylum in 2026. This is a positive development, especially since these are among the most frequently discussed and criticized titles when PhysX support was initially removed.

It looks like Nvidia is focused on about 40 well-known 32-bit PhysX games, mostly ones that people really care about. These are the same games that got the most complaints when support went away, including the ones Alex talked about at the time.

We see this as a positive step. While it may not signal a full return to a golden era of experimental PC physics, it does allow you to revisit classic games on a 50-series card with reasonable performance.

Before this update, some users resorted to extreme workarounds, such as installing an older Nvidia GPU in a spare PCIe slot solely for 32-bit PhysX CUDA acceleration. It's interesting to think that Nvidia could be using an emulator or something similar, especially given that the GTX 750 and 750 Ti haveg Vulkan support and other software-based options.

What stands out is that Nvidia decided to fix a problem with old games that don't make any money. From a branding and goodwill perspective, however, it sends a strong positive message.

Many of these titles come from the PS3 era, where PC versions often featured enhanced visuals and extra effects. We are particularly excited to see Mirror's Edge on the supported list, as it has always been a standout example of PC visuals done right.

The new physics—particularly the environmental effects and cloth simulation—gave the game a one-of-a-kind feel of motion and mood that still holds up today.

It can be a lot of fun to play old PC games again using new tools. I'm happy to play these games again because they are easy to get to very high levels and frame rates. We recently played Call of Duty: Infinite Warfare again and pushed it through high downsampling. The game, which has a way better resolution than 8K, told us that its internal one was 10240 by 4230.

Even with a 125fps limit, the screen quality was great. This kind of thing eliminates shimmering and surface aliasing. This allows you to experience the original art style in ways that weren't possible when the game was first released.

A supporter's question brought up the idea of adding more games to Nvidia's public list of titles with restored PhysX support. Early indicators show that this could be possible.

Nvidia Inspector has already been used to make other games work with the new support method, according to sources.

If that technique continues to be refined, broader compatibility could follow. For now, the fact that hardware-accelerated physics works again without requiring a second GPU is a meaningful step forward.

In the end, we believe a new GPU should support all the features of its predecessors. It's always a letdown when things stop working, especially when it happens to old favorites.

It feels like things are going back to how they should be now that Nvidia has changed its mind and added 32-bit PhysX support again. It might not be perfect, but there is no doubt that it is good news for people who love PC games.
