WoW Insider posted two great little macros for turning your graphics up, and I mean way up, and down, and I mean way down. Sometimes you want to see the forest and the trees, sometimes you want to see the curvature of the planet with little else in the way. (There’s probably a pvp setting you could add here with maximum distance but minimum clutter.)
Anyway, as much a reference for me as anyone else who might like it, here’s the link: LINK.
