I wanted to contribute so here it is:
This is the new macro to increase your WoW graphics, it is also updated for WOTLK!
/console overridefarclip 1
/console farclip 1600
/console horizonfarclip 6226
/console groundeffectdensity 256
/console groundeffectdist 140
/console smallcull 0
/console skycloudlod 3
/console characterAmbient
/console extshadowquality 4
/console environmentDetail 2
This will increase the overall look but will eat up lots of FPS.
Instructions: Just copy paste this into 2 macros, since all of that does not fit into one.
This is the macro if anyone wants medium settings/low settings:
