Multi Core Client Bug and how to fix it

Multi Core Client Bug and how to fix it 27% BOOST
Hello I have noticed that wow.exe is not using more than 2 cores (in my situation this is 1 real +1 virtual) its dramatically affects the performance of game
this is wow.exe by default Core0+Core1 22FPS

this is after I applied config changes to enable all cores 28FPS , IT IS 27% BOOST

go to your WTF folder and edit with notepad Config.wtf adding on the bottom this setting:
Optimal Settings for Multi-core Processors:
AUTO:
SET processAffinityMask "0" (or just DELETE entry)
2-cores: 11
SET processAffinityMask "3"
2-cores+virtual: 1010
SET processAffinityMask "5"
4-cores: 1111
SET processAffinityMask "15"
4-cores+virutal: 10101010
SET processAffinityMask "85"
8-cores: 11111111
SET processAffinityMask "255"

I have tested Vanilla and WOTLK clients as well they works fine without any changes so only TBC got this issue

So, with an i5 and processAffinityMask set to "7" :

Still with an i5 and processAffinityMask set to "15":
http://i.imgur.com/asTk83M.jpg (2 cores)
So basically, even if my CPU has 4 cores, I can't get wow to run on more than 3?
Member
this is only about how your Windows detects wow.exe you can check it by TaskManager -> Right Click on the wow.exe -> Set Affinity (top screenshot is default)
but how wow is using all available cores its a different story and we cannot change it we just have to provide all available cores to the game that it
Member
Thanks buddy!
Legit got a boost of 45% on the same spot.
Member
So that means that in reality, I should be able to set processAffinityMask to 15 right?
Member
Thanks! I was wondering why do I get 30 FPS on my GTX 1060. Only happened in the crowded area.
We need more topics/tips like this!
Member
You sir made my day from 17fps to 38!! I have 8 cores and only worked with 2. I love you man, no homo.
Member
confirmed this worked for me, using an Quad-Core AMD A8 6600K + AMD Radeon 5750 1GB. Logged in my sham and didnt move a muscle for a minute. FPS 31 to 36. Closed game, applied the change to config by settings it to "15" opened wow again and fps is hovering around 39 to 44 on the same spot, still didnt move just sat there observing the fps. Thanks a bunch for this man.

Doesn't the addon ImpulseBooster do exactly this?
