To my knowledge,
FlatOut 1 stretches and there's no obvious way to adjust the FOV, but things appear to be a little different for SoftTH users, see this thread:
flatout with softth, how to run it without stretching?
Result:
All thanks to custom D3D settings:

; SoftTH 1.09 configuration file
; by Kegetys, http://www.kegetys.net
;
[Direct3D]
; ** Advanced setting for Direct3D games **
; forceHorizontalFOV: Forces horizontal FOV to be three times as wide
How does this work ?
Is there any way to use this feature without SofTH, or without a SoftTH-ready display setup ?
