Gsync missing in Win 10 Guest

I’m running into the issue that one, the Setup Gsync option is missing. I can verify that I can use Gsync if I directly boot into Windows and disable my GT 710. So basically I can confirm the following things:

  • I have Freesync enabled on my monitor
  • My GPU can do Gsync
  • I use Windows 10
