I use nVidia. I see two options for denoising “OptiX”, and “OpenImageDenoise”. If I choose “OpenImageDenoise”, unlike “OptiX”, there is a brief lock-up time for the viewport when I tried to move or change something. That is, for a brief moment, the viewport does not change or respond, and the it changes.
Given the fact that “OptiX” is probably not available for AMD, I wonder if “OpenImageDenoise” delay also happens with a latest AMD graphics card. Or is there another viewport denoising option for AMD than the two that allows fast denoising on AMD?
