That’s the latest from Treyarch’s PC development team, who want you to stop bothering them about it. "Don't ask me to raise the FOV cap,” said Treyarch’s PC community manager on Twitter. “Max is 80. Thankyouverymuch.”
A “technical limitation” means Black Ops 2’s FOV is stuck at 80 and not a more conventional-for-PC 90, but that’ll be small comfort for the significant minority suffering from motion sickness as a result.
Field of View dictates how much of the game world is visible at any one time, indicated by an angle. A particularly narrow FOV can make certain games unplayable for a small percentage of players.
Do you experience nausea at especially high or low angles? Guild Wars 2’s FOV is fixed at an eye-crossing 65, but that’s set to be sorted in a future update.
