The FOV in this game is small. When compared to other games the maximum FOV you can have in this game is 70 to 80.
TL;DR bellow
A link to a similar post: Overwatch Forums
The FOV you can adjust is the horizontal FOV while the vertical FOV is fixed to 60 or 70.
In Team Fortress 2 you can achieve an FOV of 106 with a 16:9 monitor with the FOV set to 90, how? In that game you can adjust the FOV vertically and the game automatically adjusts the horizontal FOV. Even BFBC2 does this to a degree.
I jokingly call this game SquintWatch because that is how the game looks and feels. Don’t believe me? Try this: use a 16:9 monitor and set the game to 21:9.
That is how low your FOV is even when you’re playing on a 16:9 monitor with the game set to 16:9.
It’s so small I sometimes don’t bother tracking some targets because of the small FOV and giant weapon models… which brings me to another thing.
The weapon models are HUGE, so huge that they block important areas or even get in the way of being able to see enemy players from variable distances even if you have proper crosshair placement.
If the Devs were willing to allow us to change the objective marker opacity because it sometimes got in the way then what is stopping them from adding a viewmodel FOV slider, a mini viewmodel mode or allowing us to enable and disable them?
If the Devs did these changes then this game would not be so tiring to play with or without having a few constant BS moments.
“But…it would be unfair”
In E-sports events? No
In normal play? No, because of a few things: your FOV and preferences.
Not everyone likes to play at 110 or 140, some like it in the middle and some like it low, even though playing on a low FOV has more disadvantages and makes you motion sick. I could go on with this but doing so would make this post really long and others have already debunked the claim.
If the Developers don’t want to rework the FOV then they should allow us to adjust it vertically and horizontally with it being capped at 120 to 130.
TL;DR - The FOV is small and needs to be changed (rework or allow players to adjust both horizontal and vertical FOV) and the viewmodels are huge and block your vision and are also in need of change (options to adjust the size, mini mode or allowing players to disable them).
