Because of the scopes issue (T172400) we need PiP settings.
Additionally there should be a third option for the way of displaying through the scopes -it should be rendered as PiP.
Current scopes display allows unfair advantage for players using non-2D scopes over the players using 2D scopes.
In Arma 3 with RHS mods there are three settings for the scoped 2D, 3D, PiP. Image below:
