Can you set decimal FoV values for BFV? Overwatch has a horizontal FoV of 103, to match that I would need to set the vertical value to 70.53.
On another note I now see that the 103 FoV in Overwatch is equal to 97.06 on my 16:10 monitor. It has showed as 103 before so I guess all my conversions from Overwatch are wrong.
