No, I get that, but you're assuming that people sit far enough away from their TV when they play console games, so that the TV takes up less of their field of view than the smaller computer monitor does. I can tell you I don't do that myself. I have a 360 and a laptop with an 18" screen, and I generally sit at a distance from the TV when I'm playing a game such that the larger TV takes up about the same degree of my FOV as does the smaller laptop screen. I don't sit that close to watch a TV show, but I do for a game. I think that's pretty common practice for people playing 1-player games.
Recommended space from a TV any TV is 5-6ft. That is the only thing devs has to go on. Some games do vary their FOV even within its own franchise as COD. Blops = 65 MW3 = 55. Between 50-70 its decent amount for any TV player monitor is much more closer requiring a higher FOV to enjoy the game.
May I ask which game is that?
Bad Company 2 its old but it does support FOV even though its through ini files only.
Its changing FOV not going backwards more FOV more you can see more resulting in smaller objects. I will go post a video on xifre want to see me do it in BF3 if you want.
