Adjusting the FOV can dramatically change the look and feel of the game. Increasing the FOV improves the sense of speed but causes fish-eye lens distortion. Decreasing the FOV improves depth perception and the ability to judge distance but restricts peripheral vision.
What FOV do you use?
As an aside: if I've done trigonometry correctly, an eyepoint 77cm away from a 33cm wide monitor screen corresponds to a FOV of approximately 24°, so setting the FOV to 24° would render the most accurate visual representation of the game world. However, a FOV this small would make the game almost unplayable due to the very constrained viewport it provides. Multiple monitors would be needed to make this FOV playable.
