Well, this might be odd or stupid, but 60fps is easier to handle da baddies, and I kill stuff quickly. 30fps on the other hand.. not so well. Infact below 28 I have trouble. My sweet spot is 40+, and sweetest is 60. However 30fps is good for a horror game, because, you can't just snap to targets and headshots, the slow movements bring in the fear of the player, whereas the swift movements bring in the pride of cod. Lol make sense?
