I'm not saying ditch OpenCL and transitioning to Vulcan.
But ditch OpenCL and transitioning to Vulcan.
Worse case they might have to do a Metal version for the Mac and CUDA/Optix/Vulkan version for Windows. OpenCL is just too slow.
SESI is currently not in a easy situation for the development for the mac system. it is not only METAL it is now also ARM, that means all code must be portable cpu and gpu wise for the Karma render and Houdini.
