This updates OIDN to 2.3.0-beta. The final version is planned to be released in time for Blender 4.2 Beta. The most relevant changes for Blender:

  1. Much higher quality when denoising with accurate prefiltering in high quality mode, but at the cost of lower performance (use balanced quality mode to revert to previous high quality mode)
  2. Added new fast quality mode for 1.5-2x higher performance viewport denoising
  3. Lazy device module loading to avoid potential stability issues caused by drivers of unused devices
  4. Release CUDA primary context as soon as the OIDN device gets destroyed to prevent potential memory leaks

To enable 2 and 3, code changes are needed in Blender. PRs will be submitted very soon. Since these changes will require OIDN 2.3, the library binaries will need to be updated first.

Ref #118455

Note to self: I may need to temporarily disable the denoising tests if this upgrade changes the results.

It indeed changes some of the results.

The code changes for 2 and 3 could be done already with an #if version check. Generally we try to keep Blender building with somewhat older and newer versions of library dependencies to make things easier for Linux distributions.

The code changes for #2 are simple and already done but for #3 it's a lot more work because the current messy solution of matching OIDN devices by PCI address must be also maintained. I was hoping that we wouldn't need to maintain both solutions at the same time. So keeping backward compatibility for #3 is required as well?

For landing the libs it would be convenient if we could have some temporary #ifdefs, even if it's ugly. And then we remove them soon after. I don't mind doing the work if you have a PR with the changes.

Thanks. I finished the PR and fixed compatibility with older OIDN versions anyway because there are a few tricky details: #121362
