I would like BIS to stay and be ahead of other gamemakers.
Therefore I recommend to entertain the thought of blurrying and thinning out windowframes etc. that hinder the sight when within a vehicle/plane. This would give a far more realistic view. The trigger should be the focus point of the gamer: If he focusses on the instruments these should be shown sharp. When focussing on the horizon the frames of windows etc. (all inside objects) should blurr and also (!) thin out, especially hindering frames of windows.
The human brain exactly does that: blurr and thin out hindrances of sight.
And it does that automatically when you focus on far away things instead of focussing on the instruments in front of you.
At the moment BIS does simply show sharpened and detailed both levels: the faraway sight and the close-by things.
In reality noone would use such a vehicle/plane for it would be much to much narrowing the natural view. In other words and for example: The frames of a window are in fact and reality quite not at all any more visible if they are blurred because the eyes focus on something far away.
