Helllo, i havent had this much of problems before the patch but i go from 160 fps to 1-3 fps every 2nd minute.....I've tried every possible thing i can come up with.

Deleting cache/wtf/reinstall remove addons...change settings...dx11..vertical sync disabled.. its same in both 32 and 64 bit...so thats not the case either...

my specs:
AMD Phenom(tm) X4 955 Processor 3.20 GHz
4,00 GB Ram
64 bit windows home premium
Nvidia GeForce GTX 470
Asus M3A motherboard

any idea whats wrong? ... its only WoW aswell..
