after buyers noticed PhysX games like Borderlands 2 were mysteriously taxing their CPU instead of their GPU and either chugging or failing to work. Nvidia points to a support page from January where ...

The problem was that PhysX support on Nvidia GPUs was only possible because it used CUDA — a proprietary Nvidia platform that enabled CPU-focused programming languages to be executed on the GPU.

That's because those games defaulted to using the CPU as the PhysX processor. For context, PhysX is a proprietary technology that uses parallel processing to calculate complex physics. CPUs don't ...

If you load up a 32-bit game now with PhysX enabled (or forced in a config file) and a 50-series Nvidia GPU installed, there's a good chance the physics work will be passed to the CPU instead of ...
