The FOV slider "defaults" at 60 for all aspect ratios, it's just another graphics setting in this game, it doesn't really have a default.
Sounds a lot like a default value to me. :|
X-Plane has the same kind of "native, optional" support: you can adjust the hFOV as part of the graphic options, although no automatic adjustment is done based on your AR. Still, it's not a Vert- game because you
can adjust the hFOV. :wink: So the method section should explain how to do it, from the arbitrary but reasonable assumption that 60 is the FOV associated with 4:3.
According to FOVCalc...
FOV value for 4:3 = 60
FOV value for 16:10 = 69.43
FOV value for 16:9 = 75.18
FOV value for 48:10 = 128.61 (out of bounds)
With these values, is widescreen not Hor+ ?
