There's a bunch of FOV values to edit in Documents\My Games\Damnation\DamnGame\Config\DamnCamera.ini though.
Save yourself the trouble of using FOVCalc a dozen times: download the already-modded files and copy the file that's right for your AR.

Same method.
The vert- bike riding is painful, even though the FOV gets higher at full speed. Fortunately you can switch to a single-screen resolution and back at any time during play.
