An important developed note on the current Track IR implementation
As I don't own any Track IR hardware I cannot reasonably test this myself and has been classed as experimental and officially unsupported. If you enable Track IR the experience may be sub-par or entirely broken. I will do my best to work with any Track IR users willing to be guinea pigs and provide relevant feedback towards improving the implementation. That is no guarantee that Track IR will become an official feature in the game and I reserve the right to abandon any further development on it.

Enabling Track IR
The command-line argument "-trackir" will be needed, I recommend you create a shortcut to the Standard game exe on your desktop and add the argument in the target box as exampled below.
