I would like to see the option to customize our:
Default field of view
Zoomed in field of view
Zoomed out field of view
Customizing this would allow players to create their own settings as they want.
Humans can see about 180-200 degrees horizontally though each eye can only see about 150 degrees. The area which both eyes can see simultaneously and thus in depth is about 120 degrees. Each eye can turn to look at things within about 90 degrees without turning our heads. We have relatively good vision within 60 degrees of where we are looking though we have the very best within only a few degrees. All these values vary depending on your source.
Sitting 50 cm away from a screen that’s 50 cm across horizontally your field of view should be 50 degrees to make it appear like a window and not be any warped.
Currently on a 1920x1200 (16:10) screen I have a field of view about 84 degrees. Zooming in gives me about 50 and zooming out gives me about 110.
What values are realistic and not superhuman are quite debatable but I would very much like at least to be able to set my values to 50, 90 exactly and exactly 120 (the field that both our eyes can see).
If I had the choice I might even set the zoomed out option to 180 degrees which undeniably any person can see however in the outer 60 degrees or so we wouldn’t have any sense of depth which we still would in game though I would consider this a minor issue for the sake of realism.
Naturally having a centered field of view makes spotting enemies at a distance easier and more realistic while having a broader field of view makes CQB easier.
Currently changing your default field of view is the only thing here possible and it is only possible by changing values using notepad and even then the values entered don't seem to match at least compass readings in game perfectly.
