I was reading that the new software used in Microsofts new flight sim is in a way a demonstration to military and other agencies as to the possibilities their software is capable off, a sort of a commercial advert as its real world/ full world modelled based on satellite imagery from bing, a lot of the buildings etc are AI generated at the moment unless where they have done areas by hand, but people are replacing them with real world structures, and they are testing VR at the moment I believe.
You can also dial in realtime weather and it will base that weather on met information in real time. A lot of the graphical capability is downloaded as you go s it needs a fast net connection (60 MB) but you can cache areas too
I watched something on the forces channel re the training on the Juno and the like and they were showing the simulators used and to be honest the graphical representation looked very basic. Does that tend to be the standard across the board? I just ask out of interest.
As a demo ( Not by me) this is the likes of the stuff MSFS currently runs
This is an MB399 doing mach loop
And this of the MB399 shows the graphical capability at high altitude etc
