There was an update to Logic Pro - 10.7.4 - which apparently optimises performance for the Studio (both Max and Ultra).
Has anyone noticed a noticeable/measurable increase in performance with the 10.7.4 update?
Not really, My Max Studio has been effortlessly devouring every task in Logic since day 1.
Again, not exactly mad, but I think an M1 Pro chip would be totally up to my heaviest tasks.
