The problems become obvious when high resolution images are needed,
with fine textures and structures; then both ODIN and Optix produce
ugly and unacceptable blurry spots (clouds) and you loose texture.
This can be clearly seen in the example images at the beginning of
PetrTarasov’s post. Look at the leather texture.

This is no longer the case, look a this comparison by @Alaska

@Alaska

Blender 2.93 OIDN 1.3

Blender 3.0 OIDN 1.4 Prefilter = None

@Pinus

because the AI does not take
the noise of the preceding image sufficiently into calculation

There is a WIP optix patch for that:
