My apologizes if this has been answered and I simply haven’t dived deep enough into the rabbit hole - Can you render in E Cycles using CPU+GPU?
@bliblubli can probably tell you the answer
Yes you can, but it’s not officially supported. I give some tips in the documentation for people wanting to use it (deactivate auto tile size). It’s stable and I actually, I even have artists using E-Cycles exclusively on CPU (see Neon Alley for example) , it’s just that the out-of-the-box speedup mostly applies to CUDA GPUs.
