So I got this problem, WoW just freezes for 0,5-1 sec almost everytime I cast spells. If I relog it usually works great in the start, but when I have played some, I start to get this little freeze for every spell I cast. When I am in not-crowded places I can have 60 fps and no problem. When I pvp I have like 30 fps all the time, but I get these "screen-freezes". So it's like 30fps - freeze for 1 sec - back to 30 fps rinse and repeat. My addons are only using 7 mb.
Anyone knows how I can fix this?
