OverLap

Your whole iRacing race, without taking your eyes off the track.

Pick a widget to see it up close.

OverLap is the overlay I built for my own races and now share for free. What you see on this screen is not a video: these are its real widgets, with my own settings, moving with sample data over a still capture of iRacing.

OverLap installs on your PC

It runs on Windows next to iRacing, so downloading it on a phone gets you nowhere. Copy the link and open it on your computer.

Windows will warn you the first time because the installer is not signed. A certificate costs money every year and this is a small, free project. I’ll show you what to click.

  • Free
  • No account
  • Windows 10 and 11
  • English and Spanish

Four styles for the same race

What you see first is my own setup. Try the styles the app comes with, which change every widget at once, and then in the app you can tune each detail by hand.

Your colour

The accent marks your car in every widget, so you find yourself at a glance.

So you can see it well

There is a colour-blind palette and larger labels, and the flashing can be turned off.

Turn on only what you’ll look at

There are eleven widgets and none of them is required. Switch them on and off here, they work just as they do in the app. Those with nothing to say right now show their preview.

Put them where they suit you

Grab any widget on this screen and move it. They line up with each other and with the centre.

In the app you can also change their size by dragging the edges and their scale with the mouse wheel.

Each car with its own layout

You can save a layout for each car, and OverLap applies it by itself as soon as you get in. Pick one and watch the screen change.

If you stream

Each widget is a browser source in OBS, Streamlabs, vMix or XSplit. You place them in your scene however you like, and you can hide the overlay from the capture so it does not show twice.

Your sources

    The setup curtain

    While you are in the garage, a curtain with your words or your image covers the setup, and it lifts by itself when you go back on track. Write something and lower it.

    A second PC

    If you stream from another computer, the sources reach it over your local network with a code.

    I built it for my races and I share it.

    I’m Jesús, a frontend developer from the Canary Islands. I started OverLap because I wanted to see what I needed during a race, the way I like it, and once it worked I thought someone else might find it useful.

    It needs no account and has no subscription or paid features.

    It only reads the data

    It uses the official data iRacing offers to any program and injects nothing into the game. It only goes online to check for updates, and that can be turned off.

    Inside the headset too

    You can see a widget in VR with OpenKneeboard, a free program. You paste its address into a Web Dashboard tab and it appears with a transparent background. I tested it with a Quest 3S and Meta Horizon Link, with iRacing in OpenXR mode. The VR guide, step by step.

    What you need

    64-bit Windows 10 or 11 and iRacing in a borderless window, because the overlay does not show in exclusive fullscreen.

    Try it in your next race.

    The installer asks for no administrator rights and updates itself. The portable version installs nothing and tells you when there is a new one.

    Current version 2.8.1 What’s in this version

    The Windows warning

    The first time you open each version, SmartScreen will say it protected your PC. That happens because the installer is not signed, not because there is anything harmful in it. Click on this sample warning what you will click on yours.

    Download OverLap only from here or from GitHub, and if you like, check the file on VirusTotal before opening it.

    If you have Smart App Control turned on, it may block it outright. What to do in that case.

    How to make it go away

    This warning goes away once the installer is signed, and that takes a certificate paid for every year. If you’d like to help remove it for everyone, donations will go towards it.

    Windows protected your PC

    SmartScreen prevented an unrecognised app from starting.

    That’s all. From here the installer opens, and this version won’t warn you again.
