Required good video card for gaming if you dont have this stop reading now x]

This macro helpes to set the graphics from WoW over the limit set by blizzard it gives slightly more detail in grass and characters and in some cases non at all it works for me.

Make a macro and call it whatever you want to .. lets say Graphics on.
In the macro menu type this as command.
/console groundEffectDensity 256
/console groundEffectDist 200
/console detailDoodadAlpha 100
/console horizonfarclip 2112
/console farclip 999
/console characterAmbient

To disable the macro make a new macro and call it lets say Graphics off.
In the macro menu type this as command.
/console groundEffectDensity 16
/console groundEffectDist 1
/console horizonfarclip 1305
/console farclip 177
/console characterAmbient 1
/console smallcull 1
/console skycloudlod 1
/console detailDoodadAlpha 1

Enjoy.
