I just got a new work laptop and trying to migrate my files to 2.83. Since then all my cycles render fail under both 2.82 and 2.83 and no idea why. I moved from using an eGPU (RTX2070Super) for rendering and now I am trying to use the internal GPU of the laptop as well (also RTX2070, using the same NVidia studio driver and Blender CUDA recognising it no problem).
So ideally I would have half render times with the multi GPU setup (as eGPU bandwith shouldn’t limit that). BUT I cannot even render the simplest scene, what took me only a few minutes before with only the eGPU, because of various CUDA errors.
Any ideas how to solve this?
