The calibration tool can help you dial in your controller so it’s as accurate as it can be. Or perhaps your gamepad has a worn down thumbstick that doesn’t seem like it’s tilting as far as it could. In other cases, you may just have an old controller that needs a little help. For example, maybe you have a button that’s sticking and you aren’t sure just how much the computer is able to read from it on each press. For example, if you use a Nintendo 64 controller with a USB adapter, it will almost certainly need to be calibrated before you can use it. Although many gamepads, like the Xbox One or Xbox 360 controllers, are usually calibrated for gaming on a PC right out of the box, others may need you to calibrate them before the system recognizes all their movements with complete accuracy.
