On some systems Cubase is a beast - on others it’s a dog. Steinberg really do need to pull their finger out - Reaper and Mixbus fly on my system - I never run out of CPU before I run out of talent - I’ve had terrible CPU issues with Cubase - although the last update seems to have fixed the problem to the point where Cubase is now usable for me again on larger projects - for the first time since Cubase 7! I love Cubase but I was really close to ditching it.
