FacetracknoIR sensitivity

Recently installed facetracknoir and have found it to be very sensitive; the slightest headmovemet has it bouncing around all over the place, and even when you try keeping your head still, it still jitters around, making me nauseous tbh. I’m using Logitech C390 HD cam, centered and close to face (but not too close). Just wondered if this is a bug, or has anyone discovered a way of tweaking the settings so it behaves more like a human head should when in the cockpit.

Wouldn’t that be a facetracknoir issue?

I use OpenTrack sometimes and you can set it up like you need.
