Far Cry 4 saw its release just yesterday and already some gamers on PC are pirating it. Some have complained that the game has no field-of-view controls and Alex Hutchinson, the game director, revealed that pirated copies lacked the visual feature. Hutchison sent out a tweet earlier today addressing the issue, calling out all those who had pirated the game on PC.
The feature was indeed applied to the game via a day one patch. The screenshot below shows what happens what you turn the FOV slider up and speed up on a vehicle.
In conclusion, yes, Far Cry 4 does have FOV control. The game is now available for the PS3, PS4, Xbox 360, Xbox One, and PC.
