From time to time I do, but most of the time I play it in windowed mode so I can utilize my other monitors for other things. I usually reserve 5760x1080 for games such as BF4, PayDay2, Crysis 3, Far Cry 3, etc.
I get at least 60 FPS on all of my games with maxed out settings at that resolution, except for Crysis 3, that game requires so much graphical power its unbelievable.
Are you me? I have the whole desktop background set from the same author. It's great all around. 'Merica.
