I'm having some diffuculty playing Civilization VI.  This is only happening quiet recently, basically a few turns into a game or a saved game the grphics on my screen go haywire the game is still running and responding but the graphics prevent me from continuing.  Can anyone suggest how to get rid of this problem ?

This did occur with Rome Total War but now that is running fine and Civ IV is not!

Thanks in advance, Mike.
