It's not just related to that focus assist thing or windows update 1803 - i'm on windows 10 update 1709 and my game tabs out to desktop anytime i get a loading screen/change maps, and i have to alt-tab back in. I haven't played in a couple years and only reinstalled the game over the weekend - have been having this issue since i installed.edit: it's also not limited to Steam or Nvidia as some people suggested, as I don't use Steam and I have an AMD card. This is the only game where I'm having this issue.
