Well. We get the perfect implementation of this once the sim reaches the level of rendering the rays of global illumination and other light sources by tracing their paths…through the atmosphere that’s simulated as the real 3D volume of air mass and its other basic constituents.
That I truly hope and envision all the capable people of Asobo and Microsoft will one day succeed in making a reality, either by using the currently known technologies or by perhaps even pioneering some future novel AI powered ways.
To pioneer, why not, an environment such as the one in a flight simulator might exactly be the thing it takes for the next generation of such tech to be implemented and experimented upon.
