freetrackOPTIONS → CONTROLSDCS has extensive head tracking support and should detect your setup automatically once LookPilot is running.
A few users report DCS frame drops while LookPilot runs in the background. If you see this: close other camera apps, try a lower camera resolution in Settings -> Camera (tracking quality is driven by frame rate more than resolution), and make sure Windows' Game Mode is not throttling background apps aggressively.
DCS reads 6DoF but the neutral position is yours to define: sit in your normal flying posture, look at the center of the screen, and press Alt+C to make that the zero point. Repeat any time the seat position feels off.
Shaky or twitchy tracking is the most-reported issue across all games, and it almost always traces to the camera picture, not the game:
Press Alt+C (default) to recenter tracking on your current head position at any time - do it once seated in your normal driving position, looking at the center of your screen. If you find yourself recentering constantly, move the webcam so it faces you head-on (an off-axis camera makes turned positions read as drift) and recenter while looking at the horizon in-game, not at the camera.
If your wheel or stick misbehaves while LookPilot runs (stiff force feedback, lost input), make sure the output protocol is freetrack rather than virtual joystick - the virtual joystick device can conflict with some wheel drivers. DCS reads the FreeTrack protocol directly, so the virtual joystick is not needed.
Do I need to configure anything in the DCS axis tuning? Usually not - DCS maps TrackIR input automatically once detected (check the TrackIR column under Axis Controls if you want to verify). If the column shows nothing, restart DCS with tracking already running.
