I think mine arrives today.
Someone suggested on either this forum or the Tobii one to bind the same button to re-centre as to the headlook but I don't have the Tobii software to yet to try this. I assume there is a re-centre key in the Tobii software. The problem is that my headlook is on by X52pro so this would not work. If not maybe just a button on the keyboard, I use F12 for re-centre on my EDTracker.
Your X52 Software lets you program keys/ buttons - so if your Head look is the "E" button on the throttle (mine is by default), just set a normal keyboard key for it, then use the software to program the "E" button to that new key and set it in game. Job done
Or get voice attack and really immerse yourself.
