There is now an option in the rendering device selection where the user can explicitly disable OIDN GPU support.

This needs a better name and description, like:

Denoise on GPU
Perform denoising on GPU devices. This is significantly faster than on CPU, but requires additional GPU memory. When large scenes need more GPU memory, this option can be disabled.

Maybe for CUDA/OptiX the name could be dynamically to OpenImageDenoise on GPU since there the meaning is ambiguous.

What about something like this?

name="Allow OIDN on GPU"
description="Allow OpenImageDenoise be executed on GPU, if available and can be used, or only on CPU otherwise"

In general we should not use abbreviations like "OIDN" for users. And I prefer to avoid the word "Allow", but mentioning if available in the description is fine.

For the description I think it's also good to have an explanation about why a user might disable it, as I did in mine.

@Stefan_Werner , @brecht , Considering OIDN 2.2 update and OIDN overall support of GPU denoising on multiple vendors - shouldn't we move use_oidngpu option outside the oneAPI panel?

From reading the code, I don't think it's specific to oneAPI?

Right, sorry, my apologies for the confusion - I was mistaken due to the differences in the Cycle Settings GUI, where some checkboxes are grayed out when not available (like "Embree on GPU" and "HIP RT"), while others are hidden entirely (like Stefan's OIDN checkbox and "Metal RT" checkbox).
Maybe it worth to address this issue (in a separate PR, of course) by ensuring that all settings checkboxes are hidden when they are not available, I will take a look then.

With #117874, I prefer actually only having that per scene option and nothing in the preferences. To me this choice depends more on scene complexity than specific devices not being suitable for GPU denoising.
