Hey guys, I seem to be encountering a problem with the graphical properties of WOW, when I log in I catch a quick glimpse of the normal game play then randomly it starts having what could only be described as graphic spasms. I currently run a half decent system powered by an Nvida GTX 460. The problem seems to be caused by the game and not the hardware (I have tested games such as BF3, NFS The run etc) all of which run smoothly. I have no idea what the problem is and how to go by tackling it.

P.S. The game operated fine a few days ago. (I have ran the wow repair and had no luck.)

Help would be greatly appreciated.
