[How-To] Lower cpu usage when multiboxing or botting.
"Also If you are boting you can use these macros , file changes and advices to reduce the graphics even more and use less CPU:
* These six macros are made in more parts since there is a max lines x each so you will need for each a new macro.
Macro 1/1:
/console gxcolorbits 16
/console gxdepthbits 16
/console skycloudlod 0
/console particledensity 0.3
/console lod 0
/console fullalpha 0
/console doodadanim 0
/console mapshadows 0
/console loddist 50
/console maxlights 0
Macro 1/2

/console detaildensity 1
/console unitdrawdist 20
/console waterlod 0
/console basemip 1
/console shadowlevel 1
/console alphalevel 1
/console textureloddist 80
/console light 0

/console showwater 0
/console maxlod 0
/console watermaxlod 0
/console waterwaves 0
/console waterspecular 0

/console gxVSync 0
/console frillDensity 1
/console groundEffectDensity 16
/console groundEffectDist 1

/console maxfps 20
Macro 2/2:
/console smallcull 0

* You can also change your Config.wtf file (in WoW --> WTF folder) like this to reduce everything "lower than low" but I strongly suggest to save a copy of the original file in case you screw up anything

* You can turn off audio in each window witch may decrease CPU usage.
* You can remove any function from wow (combat text, HP tabs, all)
* Another thing you can do to reduce CPU usage is to reduce your Desktop bits to 16:
Right-Click on Desktop -> Properties -> Settings - "Color quality".
Select 16-Bit and click "Apply".
*IF you are botting with Honorbuddy
1) press Settings and Tools --> General - Log Level.--> choice none --> press save & close
2) Disable all plugins you don't need !
Many credits from all I wrote here go to OC and HB community people but I gathered many infos from more threads and added here in one so people browsing these forums can also help themselves to run more WoW clients on their CPU's without having to search to many places."
