That McCree had a very odd resistance or dead zone when pulling down on his aim. The secret technique was found by the viewer of Your OverWatch weeks ago. As most veteran FPS players know, settings that adjust your raw aim are typically unhelpful (eg mouse acceleration, turn OFF). As a surprise to us, Blizzard in secret popped a new McCree hero setting into the PTR today that allows you to turn this entire thing off to fix it entirely! In this video, FREEDO explains the setting and how it can effect your Overwatch Gameplay!
