According to foreign media reports, Nvidia has removed GPUPhysX support for all 32-bit games in its 50 series graphics cards, which means that the RTX5090 and RTX5080 (and all other RTX50 series GPUs) will not be able to pass GPU Accelerate PhysX to run games such as Snowfall, Batman: Arkham City, Borderlands 2, Ghost Recon: Standoff 2, Mirror's Edge, Assassin's Creed 4: Black Flag, and Bioshock Infinite. Instead, you'll have to rely on the CPUPhysX solution, similar to what AMDGPU has been offering for years.
It's a shame, because one of the best things about PC gaming is looking back at old games, and the hardware requirements of these PhysX games were quite high.
Nvidia said the CUDA driver will continue to support running 32-bit application binaries on GeForceRTX40, GeForceRTX30 series, GeForceRTX20/GTX16 series, GeForceGTX10 series and GeForceGTX9 series GPUs. However, it is not supported on the GeForceRTX50 series and newer architectures.
Not sure why Nvidia dropped support for them. Ironically, Mafia 2 using PhysX feels much better than the ridiculous remaster we got in 2020. Now, if you want to play the game again, you'll have to stick with an older GPU. Foreign media said that this is going backwards!
So disappointing. Nvidia has dropped the ball here. We all understand that these are old games. However, no current CPU can run these games at acceptable frame rates. So, in the blink of an eye, these games become unplayable.
I wonder if Nvidia will one day decide to correct this problem. After all, this seems to be mostly a driver issue. So, hopefully someone can hack the CUDA driver and add support for 32-bit games.
