Needs pictures... As a human, the concept of having different fields of view is kind of incomprehensible [[User:Cfive|Cfive]] 17:51, 27 Sep 2008 (PDT)

== Horizontal or vertical? ==

I'd like to see some sort of substantiation of the claim the that fov cvar is for the ''horizontal'' field of view, rather than for the ''vertical''. Because the fov cvar does not need to be changed when switching aspect ratios (from 4:3 to 16:10, for instance), how can the fov cvar possibly reflect the horizontal FOV (which must necessarily increase when increasing the aspect ratio)?

It was claimed that the FOV being defined vertically was "misinformation" by [http://developer.valvesoftware.com/w/index.php?title=Field_of_View&diff=71864&oldid=71863 this edit].

The original was correct. Source has never cropped the image when using widescreen aspect ratios. You can make comparison screenshots in any Source game with 4:3 and then 16:9. The 16:9 picture will show the same amount vertically, while displaying more horizontally. In CS 1.6, it would be the opposite: widescreen aspect ratios put the player at a disadvantage, as he would see the same amount horizontally but actually see less vertically. edit: I read a post claiming that Source games are locked at 74 vertical FoV, and that the FoV console command actually refers to ''horizontal'' FoV ''at the 4:3 aspect ratio'', which is automatically scaled higher with widescreen resolutions (http://forums.steampowered.com/forums/showpost.php?p=31476234&postcount=13). I'm not sure how one would test this though.
