WoW Settings System (CVars and Console)

Use this skill when you need to explain or work with console variables (CVars) and console commands in WoW Retail.

What CVars Are

• CVars are client configuration values that affect graphics, sound, UI, and gameplay behavior.
• Many settings in the in-game Interface options map directly to CVars.
• The authoritative, up-to-date list is on the wiki. Use it instead of copying large lists.
