Good morning, all (or afternoon, depending on where you are).
Dorico 3 on Mac OS High Sierra (10.13): I’m working on a symphony: 4 flows, 40 minutes of music total, 27 staves. I am using Noteplayer playback with its default sounds.
I uninstalled Dorico 2 (and all supporting files, I believe) when upgrading to Dorico 3.
My file is so slow. Scrolling and note input seem OK, but selecting a note has a lag of a few tenths of a second, dynamic input/delete takes almost 5 or 7 seconds, and any setting I change takes almost 30 seconds of the “the spinning Mac color wheel”.
The file is too large to attach. Setting playback template to SILENT did not reduce filesize (it’s still 2.7MB). Here is a Google drive link: https://drive.google.com/open?id=1k89WNqYlCK35aa1W8KiWsmO6OM2F-fno
And here’s a video showing how slow the file can be:
