He means the vector expansion, which gives six degrees of freedom. I also have that, and it works wonders in FS2004. On the other hand, I never try to "click" items in FS2004's 3D cockpits. I look at gauges while Track IR is active, and I look at lever positions, but I only make adjustment via hotkeys, joystick buttons and/or Game Commander voice commands. The 3D cockpit jumps around a bit to much with Track IR active to try to use mouse clicks. I agree Track IR would be nice in SB, if it was handled like in FS2004, where it is only active in the 3D-cockpit view. So, for example, if one is playing the TC in an M113, it would be active when scanning but it would shut off when aiming the M2HB. If it was active all the time, then it would be a real pain in the behind to turn it on and off.
