ZLUDA Lets AMD Radeon GPUs Run NVIDIA PhysX Games With Big FPS Gains
For those unfamiliar, ZLUDA is a tool that allows unmodified CUDA code to run on non-NVIDIA GPUs. Up until a few months ago, it was being commercially funded, but ZLUDA is back to being a weekend project for now. That said, with the latest version 6 update, AMD GPUs now have limited support for 32-bit PhysX, Blender texture support has been added, and Windows support has been improved.
It is important to note that the 32-bit PhysX support for AMD GPUs isn't yet complete. Fluid simulations remain glitchy, and loading ZLUDA at all can be tricky for Steam games. Even so, it's an important step forward, and even with preliminary support, some games show massive performance improvements.
The only example given is Mafia II(2010), but the results with PhysX enabled on an AMD Radeon RX 9070 XT go from just 26.2 FPS to 80.2 FPS with ZLUDA enabled in...
