Reduction in resource usage

So I've noticed that when i run wow at 2560x1440 at max settings i use up around 30% of my cpu power but if i run 720x556 with lowest settings the cpu usage is the same but i just get higher FPS. Is there anyway to lock the ammount of usage a application uses? i want it to run 720x556 @ lowest settings with around 30 fps at all times.

 

you can use the command :
/console maxfps 30
/console maxfpsbk 30

This will limit your fps to 30 in foreground and background.
Not sure if that's what you wanted though =x

 

Sort of, i want it to take FAR less cpu power

 

up abc

 

/console groundEffectDensity 16
/console groundEffectDist 1
/console detailDoodadAlpha 1
/console horizonfarclip 1305
/console farclip 177
/console characterambient
/console maxfps 20
/console smallcull 0
/console skycloudlod 1
/console lod 1
/console lodDist 50
/console mapShadows 0
/console anisotropic 1
/console fullAlpha 0
/console MaxLights 1
/console gxVSync 0
/console frillDensity 1
/console specular 0
/console pixelShaders 0

 

Understand that the resolution doesn't effect cpu as much as it does the gpu.

 

also understand some CC's arent built well, and the way HB works is that it can only do 1 inject per frame, so if you only have 30 frames on a very heavy CC, your performance is going to be really bad.
