Thank you for testing - that narrows it down quite a bit more as being a DP issue. I'll file a TechLink with MOTU and see if they can offer some input. It would probably help narrow things down if you and/or other Mac users contact them as well. I know plenty of DP users run large templates, so maybe it works better for others. It does sound like something MOTU will have to address. I really doubt an RX 3080 with 12G of VRAM would make much of a difference, but if that's what it takes to run DP, MOTU needs to do some optimizing (the 3080 is over $2k).Ok I take it back. I just create quickly a 500 track project.... first of all switching between tabs in the consolidated window takes a very long time. its like DP is rendering a lot of stuff before it will switch. Secondly I can't even scroll the mixer at all.
So whatever is going on, is not just Windows. And I view this as fairly serious if you are in need of large templates.
