Q: How to use the app?

Look in the faq in the app or watch this youtube video: https://www.youtube.com/watch?v=cHn3Ophjctg.

Q: When i open the overlays I don't see anything. Is it a bug?

First make sure you’re in an iRacing session and not in fullscreen(look below in technical section). If you are sure about these both things then write in #report_bug and someone will try to help you for sure (probably Istvan :D).

Q: Live positions are working strange. What I need to do?

You need to set limit of the cars in iRacing settings to the max value(63).

Q: Can I click through the overlays?

Yes, you just need to lock it. You can click the lock icon in the app or with “CTRL+SHIFT+L”. You unlock them the same way.

Q: Can I hide the overlays for a moment to look at sth behind them?

Yes, you just can hide it temporarily using “CTRL+SHIFT+H”. Then press this combination again to show them.

Q: What is BattleBot and how to use it?

In short, it is an overlay which show the delta time to nearby opponents. More info here: https://www.youtube.com/watch?v=31RfQ2nC_l4 and https://www.youtube.com/watch?v=ti_HXPlqVnQ.

Technical issues

Q: Does the app support iRacing in full-screen mode?

Currently the app does not support full-screen mode, this will be changed in a later version. You will have to run the game in windowed or borderless windowed fashion. Go to graphics settings in iRacing, then just untick fullscreen and border boxes. Currently the app does not support full-screen mode, this will be changed in a later version. You will have to run the game in windowed or borderless windowed fashion. Go to graphics settings in iRacing, then just untick fullscreen and border boxes. Then you have to restart the iRacing and it will open in borderless window.

Q: I still can't set borderless window

If you are having issues with borderless fashion, here is a more detailed guide to help you set it up. https://github.com/SIMRacingApps/SIMRacingApps/wiki/How-to-setup-iRacing-in-Windowed-Mode

Q: Any link you could point me to that would help in editing the app.ini for triples?
Q: Is there any way to change track temp from °F to °C?

Set the units to metric in Iracing. Later will be option in the app to choose °F or °C or both.

Q: Can you change the KPH TO MPH?

Set the units to imperial in Iracing.

Q: iRacing won't recognize my keyboard inputs using this overlay.

Could be because you have the focus on the overlay. It’s a transparent window, so you might not see it but you clicked on it before so iracing is not in focus anymore


Q: Does this work in VR?

Yes its supports VR natively (steam vr users only) Tutorial video: https://www.youtube.com/watch?v=uw_Vfv-13Cg

Q: Is there a plan to launch for Oculus users in the future?

Unfortunately not. It’s a completely different platform. You need to use the pin function in oculus which is given with the factory app. https://www.reddit.com/r/oculus/comments/a1cd5h/how_do_i_pin_a_window/ But there is possible workaroung. It’s explained here: https://sites.google.com/view/racelab-oculus/home?authuser=0


Q: Can i give some suggestion?

For sure. Write it in the #suggestions-ideas category. But before checking our backlog, maybe your idea on the list. https://trello.com/b/KoAeLSE5/racelabapps-status

Q: The app open source? Can i contribute?

Sorry not OSS. The only poeple who can touch the code are Istvan and unreal.

  1. Hello. I just subscribed to the professional version of racelab. I plan to use it for a while, but if you want to cancel, please tell me the procedure. thank you.

  2. Really loving the app but seriously cannot wait until I can have nVidia surround and g-sync enabled again. The app needing windowed mode means my g-sync doesn’t work properly over triples in the current configuration. Any idea when it will be available to run in full screen mode?

  3. Is it possible to see the data in the overlays from my race on another PC? I want to stream from my Notebook and show the Overlays in it.

  4. I have just gone back to the app, but when I change gears the overlays turn off, and also when I gear back up it comes back on screen? I hvae locked and not hidden via shift+ctl and H. What is going on, it is driving me mad?
