Aimbot FOV
Also called: FOV
The circle around your crosshair in which the aimbot will pick up a target. A smaller FOV is subtler and looks more human.
FOV (field of view) in a cheat menu usually means the aimbot FOV: an invisible circle around your crosshair. The aimbot only locks onto enemies inside it.
A large FOV lets the aimbot grab targets far from where you are looking, which produces big, unnatural flicks. A small FOV means it only helps when you are already close to on target, which is what a skilled player looks like.
Most cheats have a Draw FOV option that shows the circle on screen while you tune it. Turn it off once you are happy.
Not to be confused with the game's own field-of-view setting (how wide your camera is), which some cheats can also change with an FOV changer.
