Hi there im not sure if the issue is fixed but this is what i found
An old thread from 2014 in cockos forums pointed out that, at curtain zoom, the DAW no longer shows the peak from the peak file generated , but reads directly from the media item, thats why the disk and cpu usage increase a lot.
So i checked out the Desired Cache resolution settings : 300 samples/sec
That means that smallest length it can display peak from peak files is about 0.003 sec
Then i measure that length in arrange view, try zooming in and out
And surpisingly , it lagged the most when the length gets too small that it becomes a straight line. Zoom out from that point, it stops lagging, zoom in, lag like crazy
My theory is the resolution is not large enough to cover the entire arrange view that contains many tracks and when it reach the point when the DAW has to read directly many tracks at once, lag can occur. but when i zoom in more, less tracks need to be displayed, it stops lagging.
So i tried to increase the Desired Cache resolution from 300 samples/sec to 1000 samples/sec
Delete the peak files from %temp%/REAPEAK or from the project folder depends on settings
It worked
No more lagging , smooth zoom in and out.
Hope it works for you guys too
