I'd probably actually turn it *down*, if anything, to help counteract the "everything seems smaller" effect. But that's just me, and obviously not for everyone. ^^
I've found that turning it up higher to like 90 actually helps make things look bigger, while turning it down just kind of makes everything look zoomed in rather than larger.

It's sometimes possible to see weird things like where the Cuddlefish's food goes after it eats it.
Also this.
But the default FOV should be 80 or 90 now, no reason to have it automatically start at 60.
