So I found this on the official WoW boards..

I don't know if this works or not, or how powerful of a video card you need so your frame rate doesn't drop to a crawl. Give it a shot.

1. Load WoW
2. Open up macros
3. Make this macro...

/console groundEffectDensity 256
/console groundEffectDist 140
/console detailDoodadAlpha 100
/console horizonfarclip 2112
/console farclip 777
/console characterAmbient
/console smallcull 0
/console skycloudlod 3

4. Run macro
5. Close WoW
6. Open WoW, go to somewhere like Terrokar forest (or another nice zone) and get ready to go "oooooooooooooooooooh!"

What does this do?!

- The vegetation can be seen from miles away (grass flowers etc) plus there seems to be FAR more of it.
- The "bloom" effect seems to be more vivid.
- The view distance is greatly increased.
- Everything seems to be more sharp and crisp.
- The weather effects appear to be more intense.

Example:

After - http://img178.imageshack.us/img178/2902/92707134gs2.jpg

*you need a really good video card for this*


To bring it back to the old way, macro this.

/console groundEffectDensity 16
/console groundEffectDist 1
/console horizonfarclip 1305
/console farclip 177
/console characterAmbient 1
/console smallcull 1
/console skycloudlod 1
/console detailDoodadAlpha 1
