Webcam head tracking for iRacing.

Download OpenFOV-x.y.z-setup.exe from Releases and run it. The installer also fetches the Microsoft Visual C++ Runtime if your machine doesn't already have it.

On first launch Windows may show "Windows protected your PC." Click More info → Run anyway. OpenFOV is currently shipped unsigned. Once signed, this prompt goes away for new downloads.

See docs/INSTALL.md for the full install + setup + uninstall walkthrough.

1. Run OpenFOV.
2. The first-run wizard walks you through: pick a webcam → calibrate your neutral pose (look straight, press the button) → read the in-game tips → done.
3. Launch iRacing. TrackIR should be enabled by default!
4. Drive.

To recenter your view at any time, press F9.

There are known issues with getting OpenFOV connected to iRacing on some users' setups. We are working on a solution! In the meantime, see the "Issues" tab for discussion on this, and how you might be able to fix the issue manually until a new release is dropped. ETA before 6/14. Thank you for your patience!

OpenFOV writes the FreeTrack shared-memory section directly, and a bundled NPClient64.dll (clean MIT source, originally from linux-track) exposes the NaturalPoint TrackIR API to iRacing.

• Python 3.12 with PySide6 (Qt 6) for the UI
• MediaPipe FaceLandmarker for 478-landmark face tracking
• One Euro Filter for low-lag / low-jitter smoothing
• Compiled to a standalone Windows binary with Nuitka
• Wrapped in Inno Setup for installation
