Re: Trackir
In games which have freelook, but don't officially support headtracking (whether it be Track IR, Trackhat, DIY IR, camera based tracking, etc), the easy solution is to set head movement to mouse emulated input.
Squadrons doesn't have Track IR support so you can't use the unique Track IR axis. You can instead set the axis to mouse emulation (use Opentrack), and enable freelook in-game. This works really well when flying in a straight line, but now you can't input freelook and flight controls at the same time because there's a mouse + joystick conflict.
So a possible stopgap the developers might be better able to implement (now we're talking about fixing a bug, not adding support for a 3rd party app) is to fix the mouse + joystick/analogue stick freelook conflict.
Of course, it's not quite as good as official support. There are some limitations (you only get 2 axis) but it's still perfectly usable headtracking. You can look around the cockpit!
This fix would be great for headtracking, for anyone using joystick + mouse combo, and for those using gyroscopic controls on controllers (set gyro to mouse input).
