Overlays

Real-time overlays styled like the official F1 broadcasts, for broadcasting and also for drivers.

Caution

They don’t work on the web version. Use the Android, iOS or Windows app.

Plans: driver overlays (Delta, Battery, Tyres, Map) are in Essential. All real-time overlays, the OBS integration, the duel detector and the unified control panel require Pro or higher. See Plans.

Overlay server

1. In the menu, open Overlays.
2. Tap Start server. The status changes to Online.
3. Stopping the server drops the connection of every browser source in OBS.

Use in OBS

1. In the list, copy the overlay URL (Copy URL).
2. In OBS, add a Browser Source and paste the link.

Use Generate test data to send fictional drivers and check the look without real telemetry.

Use in a window (Windows)

Use Open in Window to show the overlay in a window over the game. Adjust the opacity and position, and save with Save Layout. Load Layout restores the saved layout.

Available overlays

Live (on air during the session):

Overlay	What it shows
Classification	Top 10 with gaps and best laps
Lap time (delta)	Lap comparison against the reference
Wheel, pedals and ERS	ERS level and deployment mode
Track map	Car positions on the track
Tyres | Forecast	Wear of the most worn tyre projected to the finish at the current pace
Tyres | Damage	Wear and damage between two drivers
Fuel	Car fuel
Duels	Identifies duels automatically

Post-race: only make sense after the session ends.

How each overlay behaves

• Delta: anchored to the bottom-left corner, avoids the other overlays and adjusts the number of slots to the screen width. The timer runs smoothly between telemetry packets.
• Classification: sector colors stay frozen during the lap and only one driver shows purple at a time. In timed sessions, duels use absolute time.
• Slow cars: the car that slows down in a yellow-flag sector is highlighted in yellow in the classification, and the track map pulses on that car (sonar effect).
• Track map: gives priority to the local driver’s car. Cars outside the lobby are not shown.
• Tyres: in the telemetry dashboard, hover to see the tyre history per stint (No Tyre Changes when there was no stop).

Note

The overlay server only accepts connections from the local network and validates the origin of requests. To use it in OBS on another computer, it must be on the same network.

Overlay editor

Create custom overlays in the visual editor, and rename or delete yours right in the app.
