A simple C# .NET Console application made in Windows Visual Studio Community Edition to replace Config.exe with a version which does not make any configuration changes.
The original Simbin GTR FIA Racing Game Config.exe does not work correctly with modern releases of Windows. Therefore the fix is to manually configure config.ini with the correct values for:
- VIDEOGUID (Device Identifier in DxDiag)
- VIDEOMODE (Resolution, can be found by counting from zero Display List all modes or if you have GTR 2 installed use the values from config.ini generated by GTR2Config.exe)
- VIDEOREFRESH (Refresh Rate)
VIDEOGUID can be found in a text file generated by running DxDiag and choosing Save all information.
A populated example is shown below.
VIDEOGUID=D7B71E3E-67C4-11CF-0556-64340EC2ED35
VIDEOMODE=143
VIDEOREFRESH=5However the Steam release will always launch Config.exe first. If you have an external USB display, another GPU or other display quirks it will overwrite your manual changes to config.ini.
The fix is to replace Config.exe with a version that will not make any changes to config.ini. It only looks for GTR.exe in the same directory and launches it.
