BioShock Remastered head tracking

Head Tracking for BioShock Remastered

Flatscreen head tracking for BioShock Remastered - no VR headset required. Use a webcam, phone, or any OpenTrack-compatible tracker to look around the environment by moving your head while your aim stays on the mouse. The game remains a normal monitor experience; your head just controls the camera.

- Decoupled look + aim - Look around freely with your head while your mouse aim stays independent

- 6DOF tracking - Full rotation (yaw, pitch, roll) and positional tracking (lean, peek, duck)

- Parallax-correct custom reticle - Drawn into the swap chain so bullets always land where the dot is

- Works with any OpenTrack-compatible source - Webcam, smartphone app, TrackIR, or anything that speaks OpenTrack UDP

Requirements

- A purchased copy of BioShock Remastered on Steam

- Windows 10 / 11

Installation

1. Extract this mod's zip to your game directory, OR

2. Copy xinput1_3.dll into <Steam library>/steamapps/common/BioShock Remastered/Build/Final/ (next to BioshockHD.exe)

That's it - no separate mod loader to install. xinput1_3.dll is a drop-in DLL wrapper that the game loads

automatically.

Setting Up a Tracker

Using OpenTrack (PC webcam):

- Download and install https://github.com/opentrack/opentrack/releases

- Set Input to "neuralnet tracker" (webcam) or your preferred source

- Set Output to "UDP over network" - Host: 127. 0. 0. 1, Port: 4242

- Click Start, then launch the game

Using a phone app:

- Install an OpenTrack-compatible head tracking app on your phone

- Set it to send to your PC's IP address (run ipconfig to find it) on port 4242

- Start tracking on the phone, then launch the game

on e.g. port 5252 (ensure it's open in your firewall), then send from OpenTrack to the mod on 127. 0. 0. 1 port 4242.

Two equivalent binding sets - use whichever your keyboard has:

| Action              | Nav-cluster | Chord           |

|---------------------|-------------|-----------------|

| Recenter            | `Home`      | `Ctrl+Shift+T`  |

| Toggle tracking     | `End`       | `Ctrl+Shift+Y`  |

| Cycle tracking mode | `Page Up`   | `Ctrl+Shift+G`  |

`Page Up` / `Ctrl+Shift+G` cycles tracking mode:

1. Normal head-tracked gameplay

2. Positional tracking disabled, rotational tracking enabled

3. Rotational tracking disabled, positional tracking enabled

4. Back to normal

The chord letters T/Y/G sit in a vertical strip in the centre of

the keyboard. `Ctrl+Shift+<letter>` is universally avoided by games,

so the chord set works whether or not your keyboard has a nav

Configuration (non-default FOV)

If you've changed the FOV slider in BioShock's options away from the stock value, the head-tracked reticle WILL drift

away from the actual aim point. Tell the mod your FOV manually:

1. A self-documenting bioshock_headtrack.ini is written to BioShock Remastered/Build/Final/ on first launch.

2. Open it, uncomment the fov_h line, and set it to your in-game horizontal FOV:

3. Restart the game. Valid range: 40-150°.

Troubleshooting

Mod not loading:

- xinput1_3.dll must be in Build/Final/ next to BioshockHD.exe, not the game root

- Verify game files via Steam, then reinstall the mod

No tracking response:

- Make sure your tracker is running and outputting to 127. 0. 0. 1:4242

- Press End to toggle tracking on

- Press Home to recenter

- Check firewall isn't blocking UDP port 4242

- Check the log at BioShock Remastered/Build/Final/bioshock_headtrack.log

Reticle drifts left/right as you turn your head:

- You're running a non-stock FOV. Set fov_h in bioshock_headtrack.ini (see Configuration)

Camera jittering:

- Increase smoothing in your tracking source (OpenTrack has a "Smoothing" filter)

- If using a phone app over WiFi, some jitter is expected - route through OpenTrack for smoothing

- Improve lighting for webcam-based tracking
