Troubleshooting Quick Reference
A few fast checks for the most common first-run issues.
Race Cast doesn't detect my sim+
Check your simulator's telemetry setup below, including required UDP/broadcast settings or plugins. Then make sure the sim is running in an active session.
Check simulator setup →No commentary is playing+
Check that your system audio output is correct. Make sure the voice pack finished downloading.
Voice pack download stuck+
Check your internet connection. Restart Race Cast to resume the download.
I can't download the installer+
Make sure your email is verified. Go to your Account page to resend verification.
Open Account →Commentary seems delayed+
Race Cast generates commentary based on live events. Some calls wait for context to build — this is by design.
My sim isn't listed+
Check the compatibility matrix. If your sim isn't supported yet, it may be planned for a future release.

Quick answers about setup, supported sims, internet requirements, and voice pack updates.
How do I start using Race Cast?+
Create an EWSimRacing account, download the Windows app, sign in, complete your simulator's telemetry setup, and check the connection before your session starts.
Do I need a special account?+
You just need an EWSimRacing account. You can sign in with email/password or Discord, and verified accounts can access Race Cast downloads.
Which simulators work right away?+
Race Cast currently supports Project Motor Racing (PMR), iRacing, Automobilista 2 (AMS2), Le Mans Ultimate (LMU), Assetto Corsa Competizione (ACC), RaceRoom Racing Experience (R3E), and rFactor 2 (rF2). Check the compatibility page for each sim's connection method and setup requirements.
Does Race Cast need an internet connection?+
Race Cast needs internet for the initial download, account sign-in, and updates. Local voice commentary can run without an internet connection once the app and voice pack are installed.
How do voice pack updates work?+
Race Cast checks for voice pack updates on launch and downloads only the new audio needed, so you do not have to re-download the full pack each time.
