I've heard that this game has a very narrow FOV, and that always bothers me, so I went out looking for a solution. I found two programs that are supposed to be able to fix this issue: Widescreen Fixer and Flawless Widescreen. The problem is that neither of their FOV sliders has the precision that I want. I want to set the FOV to 90 exactly, but I can't do that. Flawless Widescreen has an "FOV Fine Adjustment" value that goes from -20 to 20. I don't know what that translates to in actual FOV terms. Widescreen Fixer has a slider that only tells me how much I'm adding to the default FOV, which would be fine if I knew what the default FOV actually was. Can anyone help me out? I need either the game's default FOV value or more detail on how Flawless Widescreen's slider works.

I used the current version of Flawless Widescreen v.1.0.15 (x64) to change the FOV in the game. For me personally Value +4.00 seems to work the best.

Flawless Widescreen FOV Values:

[World FOV) - In: 65.00, Out: 90.10 (-1.00)
[World FOV) - In: 65.00, Out: 95.10 (+4.00)
[World FOV) - In: 65.00, Out: 100.10 (+9.00)
[World FOV) - In: 65.00, Out: 105.10 (+14.00)

Thanks for the hint.
FlawlessWidescreen is really easy to use, also portable installation is possible and the FoV is changeable via hot keys while in game.

thanks for your suggestion, it helped me. Now when I changed FOV to a bigger value, it doesn't seem like my character can see only with one eye ))))
