@fzdw11: you are correct, 4 player split screen takes up the entire screen. Other fps titles when in split screen take up the entire screen as well, so it is not an issue of power, the console and game can handle it. I dont know why it cant take up the entire screen.
As for the killfeed, fzdw11 is right, when playing 2 player split screen it is not an issue, but 3-4 player split screen the killfeed runs into the reticle. And no it is not an issue of my TV's size, I have a 55 inch Vizio so thats not the problem (for you sarcastic others out there lol). I know they have streamlined the killfeed so it does not portray as much now, but I really hope it has its own "box" to stay wihtin and does not come close to the reticle when in 3-4 player split screen.
