Breathedge FOV fine-tuning

Added 2021-03-08 01:11:17 +0000 UTC

Breathedge is another Unreal Engine 4 game that produces vert- scaling by its use of horizontal field of view. The game comes with an FOV slider of 70-120 degrees, which is alright for 21:9, as the maximum of 120 is equivalent to 106 at 16:9. However, 32:9 users and anyone looking to go beyond that value had the usual documented option of simply forcing the 70-120 values to be vertical, making the lowest possible value past modification equivalent to 102 horizontal at 16:9, which may be too much to some.

I looked into it and documented an additional way to tweak the FOV. Unlike many Unreal Engine 4 games, this one has its own custom config file and FOV command implementation, with the values 0 to 1 representing 70 to 120. One way to calculate the desired value is to subtract 70 from it, then multiple the outcome by 0.02. For example, ~133 is the horizontal 21:9 equivalent of the in-game maximum of 120 at 16:9, so we get (133-70)*0.02=1.26, which is the value we enter in the config. If we wanted the value to be 59, we'd get -0.22 and use it in the file.

Alternatively, just experiment with any increments but bear in mind that this value is unlikely to affect the menu and the cutscenes. Assuming there is just the intro cutscene, it's a non-issue, but I haven't played the game beyond the basic testing to know for sure. Using both the YFOV line and this should also be an option, making those low values like 59 handy.
