- Relatives, standings, fuel, tyre and stint overlays.
- Layouts for practice, qualifying, racing, and long endurance events.
- Streaming overlays plus Twitch chat and chat highlight overlays.

Assetto Corsa Competizione (ACC)
ACC is fully supported for most standard RaceLab overlays. It is popular for GT racing and endurance events.
- Timing, standings, relative, fuel and radar overlays.
- Layouts designed for endurance stints and driver swaps.
- Support for single screen, triples, ultrawide and VR.
ACC can behave differently depending on whether you use full-screen, borderless window, or windowed mode. If overlays disappear or flicker, check the VR & Displays and Troubleshooting pages for known fixes.

Le Mans Ultimate (LMU)
Le Mans Ultimate is still evolving, and RaceLab support is improving alongside the game. Some features may feel a little more “beta” than iRacing or ACC.
- Core timing and standings overlays for WEC-style racing.
- Layouts focused on endurance and multiclass traffic.
- Ongoing workarounds for triple-screen and window mode issues.
If overlays break your triple-screen view or shift the image, go straight to the Troubleshooting section of this site for current workarounds.

Next Steps
After choosing your main sim, we recommend moving on to:
- Overlays & Layouts – pick a layout that suits how you race and how many screens you have.
- VR & Displays – confirm your display mode and monitor setup are compatible with overlays.
- Troubleshooting – see if any known issues match what you are experiencing.
This is an unofficial help site. The aim is to collect clear, honest information about RaceLab from real users, so that you can spend more time racing and less time fighting settings.
