Windows 11 assigning graphics preferences per application

I’ve been setting up vcvrack on a new Asus Tuf Gaming laptop & was having the screen go black while Rack was running. When Rack’s window reappeared the display was frozen. Turns out with Windows 11 you have to tell it to use the dedicated graphics adapter with Rack.

What was happening was a Windows deciding on graphics performance on the fly while Rack was running & it wasn’t pretty.
