Nvidia has announced support for the upcoming Sony Playstation 4 by bringing its Nvidia PhysX and APEX software development kits (SDKs). While some details, like how will it actually run on AMD hardware, remain unclear, it is quite interesting to see that Nvidia still wants to be a part of the Playstation 4 gravy train.

As noted by Nvidia, developers use PhysX and APEX for collision detection and simulation of rigid bodies, clothing, fluids, particle systems and similar stuff across a wide range of platforms. While it is still not clear on how will Nvidia implement its PhysX and APEX SDKs on AMD hardware, Nvidia did note that both are designed to run on a variety of CPU architectures and can be accelerated by any CUDA architecture-enabled Nvidia GPU, Geforce 8-series or higher.

This move raises some eyebrows and actually makes us wonder whether Nvidia has been holding back with PhysX support. If it can work on Playstation 4 eight-core Jaguar-based custom APU, then it should work on any decent CPU today. Of course, it is still not clear if it will be run or the CPU or the GPU part of the APU, but in any case, it still shows that PhysX could work on any GPU or CPU if Nvidia really wanted it to.
