Gamecfg.ini conversion information

With the latest release, the file that contains the SDK game configuration information has changed to a new format. Previously, all game configuration data was stored in the gamecfg.ini file. This data is now stored in GameConfig.txt. Both of the these files can be found in the SteamApps\common\sourcesdk\bin directory.

When launching the new SDK update, your configuration stored in gamecfg.ini was automatically converted and stored in the new format, GameConfig.txt. Then your gamecfg.ini was renamed to gamecfg.ini.old, as it is no longer used or needed.
