Hey there,
Im using a Dual-Monitor-Setup (I guess thats what most of people have atm) and im on Exclusive Full Screen.
When I move the mouse cursor while ingame to the left/right of the monitor (depends where my 2nd monitor is) the mouse runs straight out of the game and is on the Desktop then.
So its not a real “full screen” option.
Or something like Mouse lock is missing.
Thanks
