Assetto Corsa Competizione
Connection Method
Section titled “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
Section titled “Setup Steps”- Launch Assetto Corsa Competizione.
- In DR Sim Manager, select Assetto Corsa Competizione from the Source list.
- Click Start Motion.
- Enter a session and drive — telemetry starts automatically.
No plugins, configuration files, or network settings are required.
Available Telemetry
Section titled “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: ★★★★★
Section titled “Telemetry Quality: ★★★★★”ACC uses the same shared memory structure as Assetto Corsa, providing excellent data quality for motion platforms.
Recommended Starting Settings
Section titled “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
Section titled “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
Section titled “Troubleshooting”No telemetry data
Section titled “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
Section titled “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
Section titled “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.
