and i thought my screen was filled .. wtf?

lol, I presume thats diplay for all the mods, most of that stuff can be hidden until needed, or placed on mouseover, not to mention the vast majority of it could be shrunk, & smaller fonts, especially the buffs, cast bar & raid frames. A higher resolution on that for a start would make the screen 50% cleaner. I have pretty much everything there on my UI, just you can't see it most of the time, even in raid, only raid stuff comes up

15 fps Says it all in my humble opinion.
