90 is the sweet spot and if your game does not give me the option to change it in menu. I will destroy your config files till I find the setting to change it!
when the fov of a game is too low I cant look at the screen. I get like a tickling sensation at the back of my eyes. Its totally weird. I play all games on 90 or so. Even some 3rd person games.
i hardly ever change my FOV from the default. i never get sick playing games.
i get some motion sickness on the boat just after diving, waiting for the other guys to come up. so i stopped coming up first and manage my air better. so now i come up last and no more sickness(also more enjoyable dives)
