    1. So a bit of software came out a while ago called ZLUDA and it lets running Nvidia's CUDA on AMD GPUs. The official branch crashes when trying to render Blender Cycles with CUDA but lshqqytiger's fork renders just fine.. and a little faster than AMD's own HIP RT!!

            While not much faster ZLUDA is measurably faster than HIP... and HIUP RT seemingly does nothing for me in any of these scenes?
