# Assetto Corsa Competizione

## Connection Method

**Shared Memory** — DR Sim Manager reads telemetry directly from ACC's shared memory interface at up to **200 Hz**. No setup or configuration is needed.

## Setup Steps

1. Launch **Assetto Corsa Competizione**.
2. In DR Sim Manager, select **Assetto Corsa Competizione** from the Source list.
3. Click **Start Motion**.
4. Enter a session and drive — telemetry starts automatically.

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

## Available Telemetry

ACC provides high-quality telemetry identical to Assetto Corsa:

* **Orientation**: Pitch, Roll, Heading (Yaw)
* **Acceleration**: 3-axis G-forces (lateral, longitudinal, vertical)
* **Velocity**: Full 3-axis local velocity
* **Angular Velocity**: 3-axis rotation rates
* **Speed**: Vehicle speed
* **RPM**: Engine RPM
* **Gear**: Current gear
* **Suspension**: 4-wheel suspension travel
* **Vehicle Name**: Read from static session data
* **ABS**: Anti-lock braking system status

### Telemetry Quality: ★★★★★

ACC uses the same shared memory structure as Assetto Corsa, providing excellent data quality for motion platforms.

## Recommended Starting Settings

* **Primary Cue Gain**: 70–100%
* **Smoothing**: Low to medium
* **Washout**: Medium — GT3/GT4 cars are lower G than open-wheelers, so you may want slightly higher gain

## Known Quirks

* **GT-focused physics**: ACC is specifically tuned for GT racing. The telemetry reflects realistic GT car behaviour, which may feel subtler than open-wheel sims.
* **Packet deduplication**: DR Sim Manager skips processing when the packet ID hasn't changed, ensuring efficient data handling.
* **VR users**: ACC's shared memory telemetry works identically whether running in flat screen or VR mode.

## Troubleshooting

### No telemetry data

* Ensure ACC is running and you are actively driving in a session (not in menus or replays).
* Close any other motion software that might be exclusively accessing ACC's shared memory.
* Restart both ACC and DR Sim Manager.

### Telemetry feels delayed

* Make sure your system is not overloaded. ACC is GPU-intensive — if frame rates drop very low, telemetry updates may become less frequent.
* Check that no other software (like SimHub or other motion apps) is conflicting with DR Sim Manager.

### Motion stops when exiting to pit

* Telemetry data pauses when you are not on track. This is normal — motion resumes when you return to the track.
