I have OSP installed but Quake 3 says that cg_speedometer 1 is an unknown command. Which version do I need in order to use it?
To enable the speedometer in Quake 3 OSP use the speedometer option: ch_drawSpeed (defaults to 0) - displays UPS of current player (units per second).
This needs to be typed in the console, which by default can be accessed with the ~ key.
Alternatively, you can add this command to your configuration file and invoke the configuration file when launching the game with something along the lines of the following (obviously taking into consideration any other command line parameters you're already using):
