# War Thunder

## Connection Method

**HTTP** — DR Sim Manager reads telemetry from War Thunder's built-in local web server at `http://localhost:8111`. No setup or configuration is needed — War Thunder exposes this data automatically when running.

## Setup Steps

1. Launch **War Thunder**.
2. In DR Sim Manager, select **War Thunder** from the Source list.
3. Click **Start Motion**.
4. Enter a battle — telemetry starts automatically.

No plugins, configuration files, or network settings are required.

## Available Telemetry

War Thunder provides limited but usable telemetry through its localhost interface:

* **Orientation**: Pitch, Roll, Compass heading (Yaw)
* **Acceleration**: Vertical G-force (from g-meter), longitudinal acceleration calculated from speed changes
* **Angular Velocity**: Calculated from orientation changes between frames
* **Speed**: Indicated airspeed
* **RPM**: Engine RPM
* **Altitude**: Altitude above ground
* **Vehicle Name**: Aircraft/vehicle type

### Telemetry Quality: ★★★☆☆

War Thunder's telemetry is more limited than dedicated flight sims. Lateral acceleration is not directly available, and longitudinal acceleration is calculated from speed changes with smoothing applied. The data updates at approximately 60 Hz.

## Recommended Starting Settings

* **Primary Cue Gain**: 50–80%
* **Smoothing**: Medium to high — helps compensate for calculated values
* **Washout**: Medium

## Known Quirks

* **No lateral acceleration**: War Thunder's HTTP interface does not provide lateral G-forces. DR Sim Manager relies on orientation-based motion for lateral feel.
* **Acceleration smoothing**: Longitudinal acceleration is derived from speed changes between frames and smoothed using a weighted moving average to reduce noise.
* **HTTP polling**: DR Sim Manager polls the game's web server every \~16ms (60 Hz). Very short network timeouts are used to keep latency low.
* **Vehicle type detection**: War Thunder reports the vehicle type name, which DR Sim Manager uses to identify the aircraft or ground vehicle.
* **Aircraft only**: The telemetry interface is optimized for aircraft. Ground vehicles have limited data. Ship battles provide minimal useful telemetry.

## Troubleshooting

### No telemetry data

* Ensure War Thunder is running and you are in a battle (not in hangar or menus).
* Check that War Thunder's local web interface is accessible by opening `http://localhost:8111` in a web browser while the game is running. You should see a map interface.
* If the web interface doesn't load, War Thunder may have the localhost interface disabled. Check the game's settings or `config.blk` file.

### Motion feels delayed or rough

* War Thunder's data refresh rate is limited compared to dedicated flight sims. Increase smoothing in your profile to compensate.
* Longitudinal acceleration is calculated from speed changes, which introduces a small delay. This is normal.

### Only vertical motion, no lateral

* This is a limitation of War Thunder's telemetry. It provides G-meter (vertical G) but not lateral G-forces. Motion will primarily reflect pitch, roll, and vertical forces.
