Octane, Redshift, and eevee/Cycles all work on Metal, and Renderman and Mantra are CPU-only for now -- RM/Mantra have beta-versions that are GPU enabled, and Karma is nvidia-only and RM XPU doesn't work on macs at all yet, but I don't think many people are using either in production very much yet. I think the only GPU renderer people are using in production pipelines that's really locked to NVIDIA chips is Arnold, right?

I can't speak for cycles, but Redshift is very slow on OpenCL. I've never heard of using it on Metal. I know it was written for CUDA and didn't even support OpenCL for a long time. Do you know how it runs on Metal?

I don't think V-Ray GPU will run on anything but Nvidia, and if it will then it's definitely slow.

Ah yeah forgot about V-Ray. I haven't tried Redshift on Metal, nope; all my work has been Renderman and Cycles recently. Curious to hear how well it works, people online seem to say it's pretty fast but hard to tell marketing copy from actual performance when it comes to renderers.

FWIW Cycles is definitely slower on my M2 than it was on my 3080 but it's not a huge difference -- maybe 20% slower? I still have to let the render run overnight either way haha.

Interesting. Which M2 machine are you using?

Mac Mini with M2 Pro
