Aiming at something over very long distances can be tough because their is no deadzone option in the settings (deadzone is the threshold in which a movement is detected from your controllers stick) since dayz on Xbox does not have an option to change deadzone we are currently stuck with a deadzone to high making aiming over distances hard.

-Currently their is an aim curvature slider which seems to affect deadzone but the max on the slider isn't good enough and it needs to be increased - this will probably fix the issue
