I don't think your Processor has inbuilt Graphics like most do these days, but if it does, you could set the game to use it instead of the 2080 to see if its the 2080 that's got some issue with this game.

The only other thing you could do is use an older driver, but seems like its the card itself that may have issues.

If you play at 1440p you could try 1080p with 60fps so the card isn't under much load.

Have you tried to run it in Windowed mode? Not Borderless or Fullscreen, as Borderless is known to cause issues and sometimes even Fullscreen will, worth trying any of the 3 if you haven't.
