Do you look in fortnite while aiming at the crosshairs or the opponent?
Usually you look through the crosshairs and look at the opponent.
Otherwise it makes no sense. This would mean that one does not aim at the opponent.
I mostly look at the keyboard.
I would say both, do not play Fortnite, but similar games. You look at the environment and when you see an opponent, you automatically move the mouse so that in the worst case, the Crosshair is immediately on the opponent on it, so you have both in the eye. But primarily you should look at the Crosshair.
XD
just look at the head and in the backround the crosshair
