mrniceguy,
You can look through the dialogue box - most things are self explanatory in there.
Dont save any cahnges unless absolutely necessary and needed for your game. The box can be a bit unstable so for safety purposes if you can change them manually in the game.exe folder that would be best. A few of the settings can cause your game to go haywire especially if you are messing with the MP settings - they can be a nightmare in editor.
Malke sue you have a backups of of your folders before changing settings.
