- (0) CPU
- (1) CUDA Geforce card (GPU)
- (2) Network
I set the device by using
RhinoCycles_SelectDevice -> 1 (to select the CUDA device)
With this set, a regular cycles render (non-viewport) renders quickly, with SOME CPU usage. This is ok, although I’d rather see very little CPU impact when CUDA is selected.
But when I switch the viewport to Cycles, my CPU goes up to 100% (fans speed up). This is NOT good. I expect the rendering to be done on the GPU and leave my CPU mostly alone, when I select the GPU as the device.
Is there a tie-in missing between the settings for the viewport render, and a regular cycles external-window render?
I also noticed that the viewport render kept increasing in passes, way beyond what the cycles engine is set to go to, whereas the regular render stops at 200 samples, not matter what the engine is set to.
Is there a setting I’m missing somewhere to APPLY the settings to the engine? Just curious.
