I have tried this today with FSX and a registered version of OpusFSX and FacetrackNOIP. Works fine until livecamera is enabled and then I get a strange stuttering/ghosting effect in the virtual cockpit with or without the enable trackIR setting in OpusFSX or the trackIR.exe file running from the FacetrackNOIR. Just my experience... Shame because livecamera is as valuable a feature as the headtracker to me...
