Cubase 9.5 has been pretty much unusable for me. 9.5.21 is no different. Extremely laggy UI, 1-2 second latency on start / stop. Plugin windows slow to load. Basic functions like “add audio track” slow. Window setups slow to switch on multi-monitor.
Was so bad I decided to check Reaper, Ableton and Studio One demos. No surprise, all other programs are smooth as butter. Instant response for all functions, no UI lag whatsoever. What I didn’t realize was that ALL of these programs are more snappy than I’ve ever experienced in Cubase going back 5+ years. Interesting.
For now I’m sticking with 9.0.40, as it’s workable. But something is definitely up with 9.5. on certain systems.
For the record I’m on Windows 10, i7 8700K, NVMe drive for OS and various SSD drives for projects, sample libraries, etc. 1050TI GPU, 32GB Ram. Cubase should be rocket fast on this system, but 9.5 is laggy af, even in an empty project and doing basic functions. I am speculating that some of this has to do with multi-monitor setup, or severe USB / MIdi device problems, but haven’t had a chance to test with everything disconnected. But all other programs have no problems with the same setup so whatever.
