On your driving screen

Drive with an in-game overlay

The RealRacer Overlay Windows app places transparent panels over windowed or borderless iRacing. OBS is optional for driving.

Checking the Windows download…
The overlay supports iRacing; exclusive fullscreen and VR are not supported.

Open the Windows app

  1. Start your claimed RealRacer Connector on the PC running iRacing.
  2. Extract the whole Windows ZIP. Open the RealRacerOverlay folder, then RealRacerOverlay.exe. Keep each app’s folder intact, including its runtime files and notices.
  3. In iRacing, choose windowed or borderless mode and enter your session. Stay stationary while setting up.

Opening the overlay does not start, end or record a session. Connector supplies your race team’s voices; the overlay is silent. Its build version appears in Settings. To update the overlay, close it and extract the latest Windows ZIP into a new folder. The separate Connector installer updates Connector only.

Apply your private link

  1. Choose Broadcast and your widgets above, then connect your rig and copy its private URL. You can reuse a URL already saved in your OBS Browser Source.
  2. In the Windows app’s Settings, paste the URL and choose Save and show in iRacing.
  3. Return to iRacing. Check that the overlay says Live and that gear, speed and inputs match the sim.

The Windows app always uses transparent Broadcast panels. It follows the game window; the OBS canvas size above does not set its size. After changing widgets, units or opacity here, copy and save the updated URL in the app.

Position it and drive

  1. While stationary, press Ctrl + Alt + O to hide or show the overlay. Check your wheel, pedals and mouse still control the sim through the panels.
  2. Use the orange R icon in the Windows tray → Settings to adjust Overlay size and horizontal/vertical position. The display starts centred, including on ultrawide and triple-screen windows. Reduce size below 100% for more room to reposition it, then choose Save and show in iRacing to apply your changes.
  3. Choose Edit panel layout… to move individual panels in a sample preview. Drag a labelled handle to move a panel and its resize handle to scale it; positions snap to a grid. Choose Save & lock to keep the layout on this PC. Cancel discards edits; Reset layout restores defaults before saving.
  4. Return to the sim to see your layout. The overlay hides when you switch to another app or minimize iRacing. Use the tray’s Quit to close it.

Keep the track and mirrors clear. If the shortcut is unavailable, use Hide/Show in the tray menu. For a second-screen browser view, choose Driver dashboard above instead.

For your audience

Record or stream with OBS

Add RealRacer to the recording or stream your audience sees. The Browser Source is a video layer in OBS; use the Windows app above for a transparent overlay on your driving screen.

2

Add it to OBS

  1. Open OBS and your recording scene. Add your sim with Sources → + → Game Capture.
  2. Add Sources → + → Browser. Name it RealRacer, leave Local file off and paste your private URL.
  3. Set Width to 1920 and Height to 1080. Leave Custom CSS at its default.
  4. Leave Shutdown source when not visible and Refresh browser source when scene becomes active unchecked.
  5. Put RealRacer above Game Capture in Sources. Right-click → Transform → Fit to screen, then lock the source.

No chroma key. The Broadcast preset is already transparent. Changing the studio settings requires copying the updated URL into OBS.

Check the first lap

  1. Start the Connector and confirm it is claimed by the same RealRacer account selected above.
  2. Enter your simulator and get in the car. The overlay should change from Waiting to Live.
  3. Check gear, speed, lap clock, steering and pedal inputs against the sim. A delta or split can stay blank until its reference exists.
  4. Record 30 seconds locally in OBS. Review the output for clear text and transparent space around the panels.
  5. Hide/show the Browser Source, then exit the sim. Telemetry should recover when shown and stop displaying live values after exit.

Practice or a partial grid may have no classification. Fuel, heart rate and other channels appear only when supplied. Demo is sample data and never connects to your rig.

Hear one race team

The overlay displays captions; it does not play a second copy of the voices.

  1. On Windows, capture the Connector with Application Audio Capture, or capture its playback device using Desktop Audio.
  2. Use one route for the Connector. Capturing the same output twice causes echo.
  3. Check the OBS mixer while RealRacer speaks and listen back to the local recording.

If you also use the Windows overlay, review a local recording for a doubled HUD. Some capture methods include desktop overlays; keep only one visible copy in the recording.

If something looks wrong

Waiting for your simulator, or no PC listed

Claim your Windows Connector from the Home, then reload this page. Choose that PC, create a link and enter a session. The Mac browser and OBS use separate browser storage; signing in to Chrome alone does not connect OBS.

Telemetry paused, or the wrong session

Check the selected PC and its Connector connection. Garage/pause behavior varies by sim. An interrupted feed clears moving values; it never falls back to sample driving. If you replace the private link, update it in the Windows overlay app and every OBS scene using it.

The in-game overlay is missing or covers too much of the view

Open the Windows preview app and return to windowed or borderless iRacing. It hides while another app or its Settings window is in front. Use Ctrl+Alt+O or the orange R tray menu to show it. In Settings, reduce Overlay size or reposition it, and choose fewer widgets here before copying the updated URL into the app. Choose Save and show in iRacing to apply changes and close Settings. A normal browser window cannot provide the transparent in-game view.

A dark rectangle, clipped panels or tiny text

Choose Broadcast for a transparent source. Match Browser Source Width/Height to the canvas listed above, reset any crop, then Fit to screen. Driver dashboard intentionally has a dark background. A normal Chrome/Edge window cannot become a transparent desktop overlay.

Captions but no audio, or duplicate voices

Captions come from RealRacer’s commentary feed and are not proof a speaker is playing. Confirm the Connector’s selected audio device, then choose one OBS audio capture route. The overlay itself is silent.

Private link stopped working

Sign in here and create a new link. Links are read-only and persist through a server restart, but stop working when revoked, replaced or when the PC is no longer owned by your account. Replacing a link invalidates the links in both the Windows overlay app and OBS. This page cannot retrieve an old private URL after a reload; reuse a copy you saved, or replace it and update every viewer.
