I have done a bit of searching but don’t have a definitive answer. If I was to use an approved GPU that can deal with path tracing and use it as an external GPU on my Intel Mac, will I be able to access path tracing functionality? or is there a roadblock in the way the Mac will communicate with the GPU that will stop this from working?
Hi Tessellated,
Path tracing so far requires DirectX, so no Mac unfortunately. I had an eGPU with a muscolar RX 6800 XT, so I can tell it by direct experience.
I have then built a PC for rendering to use the card. Unfortunately AMD cards are quite behind in ray tracing capabilities and have a renowned issue that may lead them to crash Twinkotion, consistently. Amd has been aware of that, but is doing nothing to fix it. So be careful.
