CUDA & OpenCL GPUs compatibility in Cycles I would like to add second GPU to my rig (currently I have GTX 1070). My budget allows two options: 1070 ti or Vega 64 (which seems to be much faster in Cycles) The question is: can a CUDA based GPU work with OpenCL card? This guy tested Radeon Pro Duo with GTX 1080, so it might be possible. I was actually kind of surprised about it. Can anyone confirm this? https://www.youtube.com/watch?v=To_N2xT6Xa8 (time 8:30)
Currenty, there is no support for AMD and nVidia GPUs to be used simultaneusly in Cycles (update is to arrive very soon from what I understand). One option is to use Radeon Pro Render engine developed by AMD. https://pro.radeon.com/en/software/prorender/
