No kidding. From Worlar's Echo Aetheryte, looking North and slightly West completely tanks my framerate. Just panning the camera in that direction makes my system chug, despite there being a huge building blocking my view of the entire map. It's clearly rendering something out of sight that is kicking me down 20-30 fps, and my GPU usage shoots to 100% in task manager. As soon as I look away, back down to 60% GPU and a smooth 60 fps.
