Thats not even it, there is no FOV changer, so we have to resort to 3rd party fov changers which work great and Infinity Ward approves of a few (i will link to them).
Fyi, ghosts is notorious right now for the major fps drops and lag spikes both on singleplayer and multiplayer. So i just got COD: Ghosts today on Steam on PC and as far as the game goes, i am still adjusting from Black Ops 2, but the game is alright, just one tiny problem: THE MAJOR LAG AND STUTTER.
