1. You need the 1.80 Alpha version for this. If you donate to the project, you can get this version. Works very good, by the way.
2. I have never tried FaceTrackNOIR in Multi player
3. Are all axis active? It seems they are de-activated in the profile.
4. Filtering was most important for me to reduce the jitter. But less jitter means more filtering that means delay between input and output.
I have switched to TIR because of this and haven't been happier. :)
But still a great program with much potential!
