Test this in both Cubase 6.5 and 9:
- Add 512 audio tracks
- At a random track, draw an event
- 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.
- 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:
Cubase 6.5 - Near full performance:
