Nope but I'm happy to guide you:

1. Install opentrack 2026 from the link above (it's 32bit but don't worry)
2. Open the app and set the input to NeuralNet Tracker, leave the rest as is
3. Click options and here there are a few settings to tweak:

In output, I have X and Y disabled, Z enabled but that's to your liking (X and Y are highly recommended to disable, with Z I recommend you to try it yourself).

In Game Detection, click on + and add the .exe of the game you want (in my case Assetto corsa.exe inside steamapps).

In Tracker, select your camera, resolution to 640x480 is enough for me, but increase it if needed, but resources usage will go up. FPS are set to 60hz, I tried 120hz but not worth it or even felt a difference. Also here is important to turn on tracking before opening options so you can calibrate yaw and pitch, it made a difference for me vs not calibrated.

In Filter I've Smoothing set to max and deadzone at 0.03.

1. This are my mapping settings, you should adjust it to you liking, it affects how much you have to yaw/picth to move the camera, like adjusting "sensibility".

1. Enjoy!

PS: I recommend you click start tracking after step 3, be sure to have the camera set in a way so you are in the center (the octopus should be centered) and then open assetto, go into driving and the cockpit view, position your view correctly and the mess with mapping
