"OpenImageDenoise on GPU" is not exactly fully fitting in default panel width, likely worth to change the default value in order to fit the string fully, or use more short one.

I still prefer this approach, but with slightly different naming and layout that I've changed. What may happen in the future is that we remove the OptiX option entirely.

I also prefer just this option and nothing in the preferences.

@brecht , What about scenario with Render on CPU and OIDN running on GPU? Currently, UI/UX do not support this, in opposite to the Optix Denoiser, where it is supported (regardless to the Cycles settings even). What your thoughts on this - should we just disallow this with 4.1 for a time being, and then figure out some way to allow users to set such config for 4.2+? Or it could be addressed somehow even for 4.1?

@Sirgienko for 4.1, we could enable GPU OIDN by default for viewport renders, and always leave it off for final renders. And then users can disable it for viewport renders with this new option.

If you want to make a PR for that, it would be appreciated.
