Is this happening to anyone else ? Literally FPS drops to around 20 during barriers.
On top Theralion and Valiona are also causing very noticeable FPS drops, along with multiple other bosses. At least for me this is the case. And I have zero issues running retail content, let alone Cata.
My PC is quite solid, and in comparison to the hardware that was available back in the days of Cata, my setup is about 5x as powerful. So there is literally no reason for any kind of FPS drops. Especially since iv never experienced anything like this in Wotlk, ever.
BugSack is not reporting any luaerrors from addons. So the only thing that comes to mind is Blizzard did not optimize something.
