DominusRex: when i close it that i got something 50 to 70% of time a black screen
Does this still happen with the latest update?
Did you try waiting a while?
Did you try Ctrl-Shift-Esc to open the Task manager?
Does Alt-F4 (then Enter) work better if you exit the game that way?
Have you tried lowering the graphics settings and resolution, or switching to Windowed or Fake Fullscreen display mode, to see if that would make a difference?
Does it still do this if you start the game directly from the '..\Divinity Original Sin 2\bin\EoCApp.exe' executable, by right clicking and running as administrator, without Galaxy running?
