Just in case there are any Prepar3d pilots left besides me
, here's a recent interview with project leader Adam Breedhttps://pcflight.net/episode-13-lockheed-martin-prepar3ds-adam-breed/
Prepar3d4.3 will be released in June, LM has no intentions to cancel the Academic version, the Prepar3d code while orginally licensed from MS belongs to LM now (that's what I understood, probably things are a bit more tricky), and version 5 will get a new graphics engine (DX12-based, I suppose). There's also some interesting info on the history of Prepar3d.
Kind regards, Michael
