This physics engine was developed by Nvidia in 2008 to support video games and to offer high-quality physics experience in video games, such as explosions, fluid dynamics and object collisions.
PhysX was a legacy tech designed to support older games and game engines based on 32-bit architecture. However, it seems like the RTX 50 series lacks this feature.
This news comes from a Redditor, who tried to play 32-bit PhysX games on the new RTX 50 series GPU and found that this GPU series doesn’t support 32-bit PhysX. Hence, gamers won’t be able to enjoy older games like Cryostasis, Batman: Arkham City etc. using RTX 50 series at high framerates.
Importance: With this update Nvidia has pivoted to prioritize more technically advanced games, excluding older titles. This implies that the RTX 50 series is more focused on AI to simulate complex interactions in real-time and integrates more sophisticated physics algorithms, which offer greater support to new 64-bit architecture games.
The confirmation of this news came from an Nvidia worker, who said that the 32-bit CUDA applications will remain unsupported on the RTX 50 series GPU. However, players will be able to run PhysX 32-bit on previous series, as those series will continue to support 32-bit PhysX.
Besides, applications using 64-bit architecture run pretty good on 50 series, as a player ran Batman: Arkham Knight and tested it.
What players of older games could do is to enable CPU PhysX as a workaround for 32-bit PhysX, similar to the approach AMD used in their GPUs. However, this will result in a compromise on performance.
Games like Mirror’s Edge, Borderlands 2, Batman: Arkham Asylum and Origins, and Assassin’s Creed IV Black Flag won’t be available to play if someone is going to get new RTX 50 Series GPU.
With all of the recent development, how do you view Nvidia’s decision to silently replace 32-bit PhysX support from the RTX 50 series GPU, leaving players unaware of the change?
