Now here is a pleasant surprise. NVIDIA has just released the source codes for Flow and PhysX GPU. The source codes that are available for Flow and PhysX are V2.2.0 and V5.6.0, respectively.
As NVIDIA noted, this PhysX release has the complete GPU source code available under the BSD-3 license. As such, NVIDIA no longer provides binaries for GPU acceleration, and users have to build the GPU binaries from source.
What this means is that someone may be able to create a GPU layer so that PhysX GPU can now run on the RTX50 series GPUs. As we’ve reported in February, NVIDIA has removed the support for CUDA 32-bit from the RTX50 series GPUs. This means that all the 32-bit games that supported PhysX GPU are no longer compatible with them.
Since the RTX50 series GPUs still support CUDA 64-bit, there are two possible solutions. The first one is for modders to release patches that replace the older 32-bit version of PhysX GPU-hardware code with a new 64-bit version. The second is to create a GPU layer that can emulate PhysX GPU on the RTX 50 series GPUs.
Interestingly enough, the first option should also provide a performance boost to all existing GPUs that can run these PhysX GPU-accelerated games. Most of the 32-bit games that used PhysX GPU had numerous optimization issues. So, a 64-bit modded version should resolve some of them. I don’t know if this is possible. However, now that the PhysX GPU source code is out, it would be cool to see if something like that can happen.
You can go ahead and download the source codes for both Flow and PhysX GPU from this link. I’ll also be sure to let you know about any mods or patches that can enable PhysX GPU 32-bit on the RTX50 GPUs once – and if – we get any.
Stay tuned for more!

While he is a die-hard PC gamer, his gaming roots can be found on consoles. John loved – and still does – the 16-bit consoles, and considers SNES to be one of the best consoles. Still, the PC platform won him over consoles. That was mainly due to 3DFX and its iconic dedicated 3D accelerator graphics card, Voodoo 2. John has also written a higher degree thesis on the “The Evolution of PC graphics cards.”
