I can't say that I like the black screen around the scope. I do not like him. But since there's nothing I can do to change this (other than installing mods), I just resigned myself.
I think that the black screen around the scope will never disappear from the game, since its absence will require additional rendering of the area outside the scope, and this is a minus FPS.
The game will ported to consoles and therefore optimization (money) is in the first place, and the absence of a black screen will only hinder this.
I'm just for the developers to get more money for their game and be able to make other cool games, so I won't be outraged, I'll just use mods that are available to all PC players.
Another question is what the developers will do if the players on the consoles don't like it )
