just gave it a little try and found it remarkably bad. the flight model is nearly nonexistent. it felt very artificial and "gamey". maybe it's the characteristics of the particular plane i was flying.
the graphics are somewhat disappointing, but the performance is quite impressive, considering how awful fsx was in its early days. i have everything on max, with a few on high. smoothing makes a lot of difference. but the ground textures were fairly bad, perhaps even worse than dcs black shark, but redeemed partially by the highly varied foliage and man made structures. they need to work on their low level noise textures.
