AMD fx 6300 & ATI R9 270x World of warcraft FPS issue

[qtmitchell]

i have installed all drivers and i have updated windows 7 so their are no more updates i can do. i have used open hardware monitor while running WoW and its using 4 cores out of 6 and only using them to about 50% on average i then checked the GPU which is running at only 40% load. what is the issue to get higher FPS.

i tried to low settings i get 60 FPS in orgrimmar i then go ultra and get 50 FPS the problem i have is in battlegrounds when it lowers to 20 FPS or in raids.

Can anyone help me please
