Dirt3TelemetryDisplay

A display for variables sent by DiRT 3 telemetry feature which bases on UDP communication.

Description

The main purpose of the program is to discover what variables the game can provide and show them changing during the gameplay. Information of each variable byte-offset of UDP packet which is sent by the game can be especially useful for DIY projects such as custom speed-o-meter or additional display with UI information from the game to keep the main screen clean.

Note that the names of the variables are guessed from various sources such as gameplay, telemetry documentation for newer DiRT games and so on, so they may not be 100% accurate as I could not find any official documentation of telemetry output for DiRT 3.

Instruction

Show instruction steps

• On application launch, the main window should look like this:

  

• UI update interval slider can be used to adjust how often the variable fields will be updated in milliseconds.

  

• Telemetry port determines to which port the application will listen. The telemetry port configuration of the game is specified in the installation section.

  

• Numeric ranges

  • UI update interval: 10-1000
  • Telemetry port: 0-65535

• Setting values out of range will be marked as shown in the screenshot below and during the listening process the program will apply last correct values.

  

• Other definitions:

  • Bytes: Value of byte offset of each variable stored in the UDP data section.
  • Field name: Name represented by each variable.
  • Field value: Value interpreted as 32-bit float or multiple float values that represent vector.

  

• To start the listening process, press Start button. During listening the configuration variables cannot be modified and their fields will be disabled until the Stop button is pressed.

Installation

Make sure to configure the hardware_settings_config.xml file which is necessary to receive the DiRT 3 telemetry packets.

hardware_settings_config.xml configuration steps

• Open the Run command window, copy %USERPROFILE%\Documents\My Games\DiRT3\hardwaresettings path, paste into text field and press OK button.

• Open hardware_settings_config.xml file with text editor of your choice.

• Scroll down to the <motion> entry.

• Replace <motion enabled="false"/>

  with <motion enabled="true" ip="127.0.0.1" port="20777" delay="1" extradata="3" />

  (Or paste it before </hardware_settings_config> end-tag if the <motion> tag does not exist.)

• Port number 20777 is recommended although it can be changed in the application later.

• Save the file.

Recommended: Install and run the DiRTTelemetryErrorFix program to overcome the bug which will crash your DiRT 3 game after each race completion with telemetry output enabled.

Dirt3TelemetryDisplay instalation steps

• Download the Dirt3TelemetryDisplay ZIP file from the releases section or this link.
• Extract the ZIP file in a folder of your choice.
• Open the folder and run Dirt3TelemetryDisplay.exe

Dependencies

• .Net Core 3.1
