It was originally posted at, a Chinese techsite, which doesn't seem to be reachable outside of the PRC - probably by China's protective networks. The developer wishes to remain anonymous till such legal issues are ironed out. AMD cold-shouldered that development and later announced its own plans to develop GPU physics processing with Havoc. Something NVIDIA didn't object to, seeing it as an opportunity to propagate PhysX and maybe highlight better performance on GeForce GPUs. This development could also have its implications on the industry, as not very long ago developers at successfully ran PhysX on ATI Radeon GPUs. To get PhysX to run, one needs to install older versions of PhysX System Software (version 8.09.04 WHQL being the latest) from its standalone installer (installs PhysX libraries without looking for NVIDIA GPUs). It comes in the form of a loader application that injects itself into the executing process. The software works as a translation layer, exchanging calls between CUDA and OpenCL or the CPU if OpenCL is not available.

Possibly better scaling of PhysX on multi-core CPUs (over OpenCL), as the regular PhysX CPU acceleration is infamous for bad multi-core scaling in performance.

Letting PhysX run on ATI GPUs as PhysX middleware uses CUDA for GPU acceleration.

Letting CUDA-accelerated software such as Badaboom make use of ATI GPUs.

This move lets CUDA work on ATI Radeon GPUs that support OpenCL, as well as x86 CPUs, since OpenCL specs allow the API to run on CPUs for development purposes. A chinese freelance developer has coded a means to get CUDA work as a middleware on OpenCL. NVIDIA's CUDA GPU compute API could be making its way to practically every PC, with an NVIDIA GPU in place, or not.
