So I know this may sound strange, but I actually really hate the visual effect that you get with 60fps (at least on a TV) it feels much more smooth (much less jittery/disorienting when I look around, even on low sensitivity settings) and enables me to be actually precise, so I would really like it if there could be an option for those of us who have just upgraded to an Xbox One X but don't have a 4K tv to maybe play the game at 30fps!
And as an added bonus, maybe have additional graphical detail since we're playing the game at half the frame rate that it is technically capable of, at only 1080P!
