Great if you can get comfortable with tracking Paul. I did try some software once (Cam2Pan I think it was called). It used your webcam to lock on to your eyes and then panned the view as required. I just found it difficult to keep my head still so that it wasn't constantly changing and disorientating me. I tried messing with the settings so that it was less sensitive but then it just became a glorified look left/right, and I still couldn't get comfortable with a view that was moving across my screen. It is the movement across the screen that enables me to judge if the car is sliding or not and so if there is movement when there is no sliding it fries my brain. Maybe it's something you need to persevere with, but tbh honest I just haven't got the time or patience.
It takes a while to get used to but once you do it becomes second nature. The dedicated TrackIR setups and Freetrack using the Wii Mote are a lot more stable than older Webcam based systems which makes a big difference.
I think it's easier for people who've not driven sims before. My brother in law tried my iRacing setup (don't tell Nim...
) and used the tracking and found it completely natural.
The biggest problem is that my old hat is getting fairly rank now and I can't really throw in into the washing machine.
