You can bind the translation movement (side to side, up and down) to your mouse, so that a click and drag would allow you to center your gunsight each time your turned your head. This is how I did it before Track IR.

Track IR is not a magic bullet. It doesn't make the game easier, it just makes it more immersive. I had an easier time aiming when I was using the mouse system above.

This is really a moot point anyway. You don't have to keep the gun-sight projection in the middle of the glass for it to work. The only sights that need to be carefully lined up are iron sights.


Cheers.
