These drivers inlcude a bug which causes all Adaptive Apps ( Fx, Steam, Media Center, and generally Windows ) which using Hardware Acceleration to utilize the Graphics Card more than they should. The results: 6-7C hotter and clocks running in full 3d mode much more than they should too. You can notice it especially on Scrolling ( jerky -even while you scroll down a folder in Windows ) or Tab Switching and generally very sluggish UI some times, after an unspecified usage and eventually a restart needed. The fan works on 60% of its power instead of 40% or at least 50%. Quite waste.
They have acknowledged the bug and said early September they will release new driver which will fix this terrible bug. And I was mistakenly blaming Mozilla. Don't make the same mistake if you notice it.
Disabling HWA It's a stopgap, but no panacea. Fx still uses HWA while scrolling.
Odd thing is that their is 0 GPU load with Firefox layers and the P-State switch happens though on XP disabling layers seems to be more efficient especially saves more Power then in this current state with the WHQL driver
Maybe it would be better to also fill a bug report in concerns with the new WHQL Driver and Firefoxs Layer behavior (though i guess Mozilla is already @ it).
That you still see GPU load is easy explainable as you still have DirectWrite and Direct2D enabled layers is only 1 part of the whole package under XP you would see immediately the difference as their is no Direct2D and DirectWrite support for it
This is absolute funny

No GPU load but excessive P-State switching @ scrolling with Firefox Layers
Layers on a new GPU is anyways questionable if it saves anything @ all on XP and my Sandy Bridge i hardly realize what should be better Performance or even Energy wise with layers (might be more important for Laptops, Notebooks and less efficient CPUs)
