Stock 2500K, 8GB, GTX670.
Basic addons (shadowed unit frames, grid, power auras, affdots, bartender, quartz, sexymap, skada, but only damage module turned on), lowest possible settings with full HD resolution.
And I still get dips below 30FPS on Malkorok HC, sometimes even close to 20 FPS I'd say.
Do you think that reinstalling WoW/addons (meh I don't want to lose my settings but you gotta do what you gotta do) will help, or is it normal?
