Quake Live Cvar Recommendations Guide
Thanks to regurge I now have hosting for my guide. It includes much of the information I've learned over the years about the various options in QL. See it here:
"There are ~1,274 commands/cvars, this takes only the most important 193 cvars and gives recommendations and often times extra info not included in the basic list. It also includes explanations for the 72 most important commands sometimes with more in-depth info."
