I use Cubase entirely for mixing down concert tracks, usually folk festivals so track counts are low usually under 24. I upgraded to Cubase Elements 15 from 13 when I bought a shiny new Mac mini M4 with 16 Gig of ram a couple months ago. My previous mixing computer was a 2018 MacBook Pro running Cubase 13. That computer worked well for the track counts and plug ins I use. Cubase 15 on the Apple Silicon machine is constantly throwing beach ball when opening plug in windows, when selecting tracks even when just hitting play on as few as eight tracks with a single reverb plug in.
Clearly I've missed some setting somewhere. Web searches turn up suggestions for turning off GUI graphics acceleration in preferences but I find no such setting. I usually mix from external drives and that worked fine for years as far back as Firewire drives. What can I do to get this to work better. Any suggestions appreciated.
