Valve.rc

Valve.rc is a file that lies inside the game / mod's cfg folder. It is a file that automatically executes convars on game launch, identical to that of the autoexec.cfg.

To create one create a text document and save it with a .rc extension inside your cfg folder. Simply place your convars inside the file with each convar on a separate line. Your valve.rc should contain these convars if you're making one:

 // load the base configuration
 //exec default.cfg

 // Setup custom controller
 exec joystick.cfg

 // run a user script file if present
 exec autoexec.cfg

 //
 // stuff command line statements
 //
 stuffcmds

 // display the startup level, remove this for background images instead of maps
 startupmenu
