🧩 Overlays – Common Issues & Workarounds

This page lists unofficial community reports about how RaceLab overlays behave across different sims. Most overlay behaviour is the same for all sims – the main differences are:

  • Some sims do not support all overlay types (or only support them in certain modes).
  • Window modes (fullscreen vs borderless vs windowed) strongly affect how overlays appear.
Scope Area Issue, Cause & Workaround (Unofficial)
All Sims Overlay Not Visible Issue: RaceLab overlay starts, but nothing appears on screen, or overlays are hidden behind the game window.

Possible causes:
• Game is running in true exclusive fullscreen and sits above the overlay window.
• Overlay is on another monitor, or outside the current screen bounds.
• Wrong Scene/Layout selected, with all panels disabled or off-screen.

Suggested checks:
• Use borderless window or windowed mode in-game where possible.
• Alt+Tab and look for RaceLab overlay windows on other monitors.
• In RaceLab, open the Layout editor and reset the layout or load a known-good preset.

Status: Common – usually window mode or layout position.
Triple / Ultrawide Users Size & Position Issue: Overlays appear stretched, too large, or placed on a side screen when using triples or very wide monitors.

Possible causes:
• Windows “main monitor” is not the same as the monitor you expect for overlays.
• DPI scaling or resolution is different between monitors.

Suggested checks:
• In Windows Display Settings, confirm which monitor is set as Main display.
• Try setting the sim and RaceLab on the same monitor and resolution first.
• Use the Layout editor to drag overlays to the correct screen and save the layout.

Status: Common for triple / mixed-resolution setups.
All Sims Performance / FPS Issue: FPS is normal with RaceLab closed, but drops significantly when overlays are enabled.

Possible causes:
• Too many overlays visible at once (especially graphs, logs and long lists).
• GPU/CPU already near 100% before overlays are added.
• VR or high-resolution rendering + overlays pushing the system over its limit.

Suggested checks:
• Start with a minimal layout (for example, only Relative + Flags).
• Turn off heavy widgets such as large telemetry graphs, logs or big tables.
• Make sure the sim is not running higher resolution or supersampling than needed.

Status: Common – strongly hardware and layout dependent.
Per Sim Overlay Support Issue: A layout loads, but some specific overlays never show in certain sims, even though they work in others.

Possible causes:
• That sim does not expose the data needed for a particular widget yet.
• Live timing / standings / extra channels are not implemented equally for all sims.

Suggested checks:
• Compare the same layout between sims to see which widgets are missing.
• Check the RaceLab Garage / Roadmap for notes on which widgets are supported per sim.
• If in doubt, treat the missing widget as “not yet supported” for that sim rather than a fault.

Status: By design – overlay support varies per title.
Multi-sim Users Reusing Layouts Issue: A layout cloned or reused across sims looks slightly different or needs extra adjustment in some titles.

Possible causes:
• Different safe areas / HUD regions in each sim.
• Different camera FOV or aspect ratio affecting perceived overlay size.

Workaround:
• Treat each sim as needing a final tweak pass even when using the same base layout.
• Keep one “master layout” (for example from iRacing) and create per-sim variants with small position tweaks.

Status: Expected – sims do not share identical HUD spaces.
