The official release is compiled with the viewport denoiser enabled. I would suggest you try to temporarily start Blender with factory preferences, just to make sure that this is not caused by broken user preferences.

Open Blender's installation directory
Double click on the blender_factory_startup.cmd

Check if viewport denoising is still not available as option

For future bug reports, please create your report through Help > Report a Bug in Blender and follow the submission template .

Does this also happen when you move Blender into a path that does not contain any Cyrillic characters?

%USERPROFILE% = C:\Users\Venga
%PROGRAMFILES% = C:\Program Files (and Blender path C:\Program Files\Blender Foundation\Blender 2.91)
Don't use paths with Cyrillic characters.

@blendask Could you please check if Blender 2.92 allows you to select the OptiX denoiser.

@blendask Could you please check if [Blender 2.92 ](https://builder.blender.org/download/) allows you to select the OptiX denoiser.

This is most likely resolved due to the fixed handling of UTF-16 on Windows. I'm closing the ticket as resolved, should the problem occur again, please let us know.
