I have track-IR4 with vector expansion. Tried recently the latest track-IR5 software which works in the old IL2 sim perfectly but does not at all react in Cliffs of Dover. So I reinstalled my "old" latest version of track-IR4 software. That works in Il2-CoD also in 6DOF mode, no problem!
But maybe I should change the movement settings from "agressive" to "default". I´ll try to play arround with it tonight until I find the best settings for the 109 cockpit gunsights.
Thanks for all your helpful answers.

Btw with the new software did you make sure you selected the vector rather than the pro clip.

I use a clip and had problems before, it was because the software kept reverting back to the vector rather than the pro clip.

P.s. The clip rocks
