Denoise in Lightroom Classic became 3 times slower in version 15.6 than in the previous version

Today I reported that the Denoise function in Lightroom Classic became very slow, when compared with the previous version (3 times slower). I got an answer, from an expert, that says “The real reason for the slow down is that Lightroom Classic is no longer using the Apple Neural Engine for denoise, because that still caused quality issues.” I googled the subject and I retrieved the information that since June 2026 all versions of LRC are using again the Apple Neural Engine. Can anyone clarify what is going on?This is a quite annoying situation, as I need to denoise batches of files and the overall time became prohibitive.
