How does stretched resolution affect FOV?

[filip74]

Hi, would anybody please explain to me how stretched resolutions affect your FOV? For example if I were to play csgo with a 4:3 resolution (with the default FOV of 90) stretched onto a 16:9 monitor what would the FOV be? Would it stay 90 as if I played black bars, would it be 106.26 as with a normal 16:9 or something entirely different? If it is something entirely different is there a formula one can use to calculate the FOV?

I would be very thankful if somebody would share their knowledge <3

blackbars shows 90 of the 106 horizontal units

stretched takes the 90  and streches them to fit 16;9  ( i dont like it cuz it needlessly messes with your aim)

 

the calculator has an option that shows you the fov

Fortunate is correct, but his wording is a little misleading for stretched...

Stretched doesn't increase your FOV to 106 units, it just fills the screen with the same horizontal FOV. If you see 90 degrees of the game world Horizontally at 4:3, you will still see 90 degrees horizontal if you stretch it to a 16:9 screen.

Stretched is not usually recommended from a sensitivity perspective, because you end up with a faster horizontal sensitivity than vertical sensitivity within screen space. The targets are fatter of course, and the approach is debatable overall - but IMO it is best paired with an understanding of the impact on aim, and probably a different x/y sensitivity, which isn't always possible depending on mouse driver or game.
