Since the new UI launch several of my boxes have gone from smooth FPS to what I would call "a slideshow" of like 10 FPS that causes them to go into a wide orbit while auto-following my main toon. This of course causes problems in zones where that wide orbit can take them into additional critters. I run a custom UI. (well there's your problem..) If I set them to default UI they seem to go back to normal. So my question for the masses -- has anyone yet identified what types of things in a custom UI might degrade performance under the new architecture? Only thing I can think of is maybe the compass since it has to update every frame of a turning character?
