I find TiR makes me nauseas in IL2.
I use and prefer the mouse in left hand MSFFB2 in the right and key board to my far left.
The advantage as a mud mover for me is I can leave the mouse set in a fixed point looking in target area direction.
Some pilots say they cant fly without TiR , I find those ones usually cursing on comms that TiR has stopped working or has got stuck
IIRC there's some alternatives out there to TiR that look like fun to develop.
