Hmm, yeah I guess I should try a fresh install. But I have the same experience on my 2012 macbook pro, Nuendo 7 is snappy and fine. But on everything newer, Nuendo or Cubase, there is noticeble gui latency, delay on clicking buttons, slower meters etc.
I have always seen a gui performace punishment with lots of edits. Like multiple drum tracks edited to grid. But this is worse.
(BTW Spectralayers is like working on a web java application, Mouse pointer is really laggy)
I opened N7 on my macbook with the same size projects the other day and it was night and day. Still slower then N1.6 on my old PC but what isn’t…
I still have my SSD’s on the old slow sata connectors. I guess a nice PCI nvme like that sonnet one should speed things up…?
best regards,
Johannes
