Short description of error
OptiX denoising was recently enabled for all Maxwell+ cards (rB473aaa389cc).
However, viewport denoising does not seem to work when CUDA is set in preferences. It _does_ work if I select OptiX in preferences OR if I do a final render while in CUDA mode.
Basically I see the following:
|Setting||Does Viewport OptiX denoising work||Does Final render OptiX denoising work|
|CUDA||No - this bug||Yes|
Exact steps for others to reproduce the error
- Open attached .blend
- Use a non-RTX nVidia graphics card (latest drivers as of May 27th)
- Ensure CUDA is selected in preferences
- Go to viewport and observe no denoising is occurring
