Developer @phamblnn demonstrated porting the PhysX physics engine to Radeon GPUs during the AMD Robotics Hackathon. The project involved writing 200+ custom rigid body kernels, achieving about 60% of the performance of an RTX 5090 on a 2-year-old Radeon Pro W7900. This move lowers the barrier for physics simulation outside the Nvidia ecosystem, with community calls for AMD to officially support such efforts.
