Bissl rumgegoogelt, da mir meine Vorlesung zu langweilig ist, dabei habe ich das hier gefunden:
"Well, I got the P150EM with 7970M and WoW is affected by Enduro, but I have found a way of improving the FPS gratly.
It works in DX11 + 64-bit client. May not work with 32-bit.
Tested in various locations. For example crowded Stormwind Trade District, in front of the AH.
I had 15-25fps there regardless of graphic settings. No matter whether on "low" or "ultra".
The way to deal with it is to edit WTF/Config.wtf file by changing (if you have Core i7):
SET processAffinityMask "3"
To:
SET processAffinityMask "252"
Thanks to it the FPS in this location jumped from 15-25fps to 40-50fps on "ultra" settings (>60fps in the rest of Stormwind).
From 20 to around 30-50 in the crowded Shrine in Pandaria."
Vllt hilft es dir ja ein wenig, hier nochmal die ausführliche Quelle:
