Asobo seem to be the brought in team of scenery and weather coders, doing a great job,
they inherited the underperforming aircraft flight models, allllllllll the bugs in so many planes and a horrible outdated, slow, and bug ridden graphics engine from the dinosaur MS Flightsimulator 95 2004 X team(s) it seems, and Asobo prob left all of that side of the sim to these guys.
Landing visibility and scenery simulation, which is the most important part of the simulation, is great (Asobo),
all the bugs and graphics engine cra–p (FS2 does 10x the better job), no so much (no thanks Microsoft).
MS should just buy Aerofly FS2 Flight Simulator corporation and their coders (FS2 crazy fast but a tad arcady), and pretty soon we would have an actual good sim.
