Default value: "90"
Saved to config.cfg: no

fov stands for "Field of Vision". Its default is "90" (degrees). That is how much you can see on the screen. If you set it higher, like 135, you would see more of the world, like viewing through a wide-angle camera lens. If you set it lower, like 45, it would produce the same effect as zooming in.

Most engines clamp the value between 10 and 170.

The FOV variable specifies horizontal field of view assuming a 4x3 aspect ratio. Vertically, it stays consistent throughout the possible aspect ratios. For example; the FOV can be 90 (of course), but if you were to be playing the game on a 16x9 display, it would display as 120 degrees.
