TIR 4 or TIR 5

[JimAllen]

I have a Tir 4 unit which I have had for several years. My question is should I use TIR 4 or TIR 5 software to run it.
Is there any advantage of using one over the other?

The TrackIR 5 software offers a much improved experience, in my opinion. Technically, they are similar in what they accomplish (though the 5.x version does include better background light filtering), but from a usability standpoint, the 5.x software has a better approach--especially when you're creating a profile. Preview options, curve tweaking options, and profile management/mapping are all significantly improved in the newest software.
