Happens occasionally. Aircraft gunsight does not light up with the center of the bullet stream. Looks like the center of the aiming retical is centered but bullets center off to the right
Do you use trackIR or some other head tracking? If so, there is a long time bug where if you hit respawn while head tracking or mouse look is enabled it will cause that. A respawn in normal view should clear it.
I use free look like most pilots. no other software. I used the right stick on an xbox controller. It is a problem bug as you do not know its there until you fire your weapon in the air. Shouldnt have to do a test burst everytime you take off
