We’ve noticed issue #2 as well. Now we make sure never to minimize the nv2 window on our server. The same would apply to clients.
The cause is a Windows “feature” which immediately swaps out minimized programs, even if there’s plenty of memory to spare.
If you have a large amount of ram, it might be a good idea to disable swap altogether, which should resolve this issue.
If developers read this, Microsoft has an article describing one way to defeat the swap-on-minimize feature, though it might not be an easy fix.
