Using DRE, it is recommended to set Max Cars to 63 in iRacing.
Otherwise, live positions and some timing info may be distorted and false due to connection drop-outs. This is a limitation by iRacing unfortunately as we cannot expect iRacing to stream all 63 cars constantly even with Max Cars = 63.
To change Max Cars in iRacing:
- Start an iRacing session
- Open iRacing Options
- Click on Graphics
- Locate Max Cars
- Set it to 63
- The change might require a session restart to take effect
Change Max Cars via ini files:
- Make sure iRacing and the UI is closed
- Open your user’s documents folder
- Enter the iRacing folder at C:\Users\[USER]\Documents\iRacing
- Open the App.ini
- Search for serverTransmitMaxCars
- Change this to 63
- Save and close the ini file
