The problem is that Nvidia pulls proprietary nonsense out of their ass, specifically to say “AMD can’t do [blank]!”
Physics. Sound. Compute. Hair. Raytracing. Upscaling. And on and on and on, aggressively poised to be incompatible. CUDA is fifteen years old and Nvidia still threatens anyone who tries cross-compiling it to SPIR-V or OpenCL.
This is anti-competitive behavior from a blatant monopoly. They have supermajority market share - they are abusing it. The right answer is to shatter this corporation.
