Ya, Cubase 10 on Win10 with good hardware drivers such as RME seems extremely impressive. The task manager showed almost 100% CPU utilization with 72 instances, but I added 8 more and got to 80, and it showed exactly 100% with all cores pegged at 100% and yet there were zero dropouts and the system was still responsive. (This test was with a large buffer of course).
I do love me some OSX, but damn....
