I have two sites that has a ton of info and explains the cvars . This one also explains a config and has a downloadable one set with default values .
http://antman.info/wolf/cvar/#.U22c4Y0U_3gThis one is very informative and walks you through things with more explanation.
http://forum.splatterladder.com/index.php?showtopic=9497&mode=threaded&pid=60601You can pick and choose and put in console /seta saves in profile for that server and mod if you switch to a different server and mod you have to redo or you can make a loadable config with all these settings and make binds that way all you have to do when you play elsewhere is load config and all those settings automatically load.
There is a lot of eye opening things here and if you need help or something explained just ask (I'm sure Zelly would also help). I have created probably 50 different configs and I am very experienced also If it seems like just too much I could get some of your preferences and ask you a few questions and build you one and walk you through where to put and how to load, the good thing is if you mess up anything you can always restore the original default config for the game . I hope this is helpful and opens you up to a more enjoyable Enemy Territory experience.
