You can turn off QB Vision at anytime except when playing online. Note that by turning off this feature, you are also disabling QB Precision Placement, as it requires QB Vision to work.

To do so:

1. Access the options menu (this is located in different areas depending on what mode you are in, but if you are on the field, simply press the Start button).
2. Choose Settings.
3. Choose Gameplay.
4. Choose Custom Game.
5. Set QB Vision to Off.

If you are playing a local game with two players, each player will have to turn this option off individually.
