When I first started using Track IR it was uncomfortable. Took a bit of getting used to. Some people even get vertigo, but I didn't, and I think most aren't bothered by that. But after about a week I started to get the hang of it, and now I wouldn't go back to the hat switch unless I had to. It really is a great program, and a helluva lot cheaper than VR. Initial setup will take some tweeking until you get it just right, for you, but it's fun to play with that and experiment with.
