Post some examples of where it fails. I have ON1 photo that touts its fancy nonoise AI and usually the results with DT are as good if not better. Maybe you are simply using profiled denoise in DT and the profile for your hardware maybe could be better???
I suspect you have watched @rawfiner videos so as to get the most out of the 4 or 5 ways to denoise in DT??
In any case an example of “poor” performance would be useful on a path to better…
