TrackIR is a welcome addition, though the values are inverted in game. I just inverted all of the controls in TrackIR and it worked much better. The X, Y and Z values tend to pitch the body of the driver out and into the car depending on how much you move. It's a weird sensation. So I just disabled X, Y and Z movements and it's much easier to use. I didn't feel like troubleshooting X, Y and Z movements but I suspect if I reduce those values and limit them, I should be good to go.
The visual field adjustments are AWESOME. So glad I can very easily move the player's head to where I need it. I ended up moving it quite a bit back, slightly left and up (since I'm tall). Once I changed from the Lambo to the Porsche, the view needed to be moved backward again, but I just left it. I don't know if those view settings are "per car" or universal, but if they could be per car make/model, that might be nice. Or if you could save versions similar to the overall settings, that would be good.
21x9 4k with TrackIR is better than VR (never tried VR though). Sooooooo nice to be able to see where I'm going now.
