Hello SoundOfMusic,
Hauptwerk doesn't yet (v7) have specific optimisation for CPUs whose cores vary in performance (as found in the new Intel 12th-generation CPUs). However, in our testing, and based on the results that people have reported to us (e.g.: viewtopic.php?f=16&t=19986&start=15#p151522 ) performance is very good anyway, and better than previous-generation CPUs would have achieved.
