I forgot what its called but I hate that cinematic mode where they put bars at the top and bottom of the screen to make it seem like a movie. It is the stupidest effect I have seen in my life... Instead of being able to see more of the game, here, see less! Like da faq
That's called letterboxing.
It's good because it shows more of the game by increasing the field of view. It's not just cutting off the top and bottom haha.
Plus games don't have to render those extra pixels so it helps with graphics too.
