Move the view around
→ Performance in Cubase 9 is vastly lower than Cubase 6.5 with an identical project / graphical load. Please fix these kind of optimization problems.
Findings:
The slowdown is worse when the playhead cursor is within view, even when it’s static.
Using the scrollbars, I found mostly the vertical scrolling is slow. The horizontal scrolling is smooth but only if the playhead isn’t in view.
Resizing the track width of a lot of tracks is clearly slower in 9 than in 6.
Test with 512 audio tracks Cubase 9 - about 20 fps and stuttery:
Cubase 6.5 - 60 fps and smooth (but GIF is a lower framerate):
Extreme test with 2048 folder tracks Cubase 9 - Low performance, note the slow resizing:
Ah didn’t know, that’s to bad, regarding this observation together with your other observations on high track counts, is there a nbr of tracks where this gradually starts to happen on your system? If so about what amount where this becomes noticable and what’s your CPU utilization while hovering your mouse, as per windows task manager?
Are you running windows WHQL videodrivers, or most recent AMD ones?
Great, ThnX I appreciate the difference between v6 and v9, but it’s always good to get some perspective.
With <100 tracks it isn’t that noticeable?
When idle (not hovering the mouse) how much does the CPU load drop then?
Also when you do the same, but for example in a pianoroll window, do you experience the same slowdown? Or is it only in the mixer or arrangement window?
I currently don’t have access to my DAW, but will try to test somewhere during the weekend as well
So it’s fair to say that fast hovering is very demanding on the CPU? 20% in task manager is a condiderable load?
Question still is why v6 feels snappier on your system.
Is the load when hovering the same on v6 as v9? Or does V6 have a lower load when fast hovering?
We’re not talking about fast hovering, but scrolling the view. “Hovering” gives me 1-3% cpu usage with 100 audio tracks. Most of those hover performance issues should be gone (on Windows). I reported the one in the Key Editor one and it was solved in .20
Dear Raphie, I am sure you want to help, but none of your last 40 posts did help anyone, did they? You mention this and that, assume one thing or the other, and most of the time doubt what others write or explain why you don’t care about their problems or findings. But there’s simply no idea, no support for anyone coming out of the lines you write. Just a bad mood that I get when I read your comments most of the time. Destructive statements leading to nothing but time killing conversation, shouting ‘no!’ to the world.
Could it be that… well… are you simply bored and sad? Make some music. Be creative. That helps me when I feel that way.
No offense meant. I don’t judge you as a person because I don’t know you at all, just the things you wrote in this web forum in the last days.
nice research djw!
what i can add, you dont need add 500+ audio tracks, just Open heavy project in 6.5 and 9. you will see same resoults
also if you change size in project windows where no Buttons/text etc. there no lags, if you change size at buttons area you can see lags, probably its Redraw again.
