I have some screenshots here (running in lowest settings as my computer isn't exactly NASA standard). Trees and grass are set to "Low", as they're some good FPS killers and, in such close combat, I can't afford any lag.
Rise of Flight did a nice job in archieving eye-candy in a realistic way, specially with the reflections. Not really important on this discussion, anyway, but I think they also got the 'drama' factor right. I felt a bit weird after my plane got one wing bent, I tried to recover but, already low, the wing was ripped of and it dived towards the ground... This only happened once in IL-2, there it's just hit Ctrl+E and see if the pilot jumps, and if he smashes into the ground. When you can't even jump, things are different.
