@roonelos editing from FCSETUP.ini to 144hz wont show up in ingame settings, it will show as 60hz although its running in 144hz, only thing is if you edit via FCSETUP.ini make sure you dont change anything in display settings or it will get reset, and yea even if its on 144hz there will still be shutters, what i did was turn of vsync ingame and exit game, FCSETUP.ini = 240hz save and start the game, also off vsync in nvidia panel or set to adative, the game runs little better
