Lots of it looks beautiful, but without icons, I can't see any of the planes unless the background is blue sky. Maybe it's better in the real game as opposed to Youtube video, but it is easy to keep track of an airplane in a close-in fight in real life, regardless of background, which is why I'm in favor of icons. I hated how WWII Online did icons, for example, years ago. In WWIIOL's quest to make the situation more realistic, it actually made it horribly less realistic.
In the first few minutes of the video, did you have tracers turned off? I didn't see any tracers or flashes of hits despite lots of firing, it looking like you were on target enough, and the enemies sometimes not maneuvering all that hard.
Is there any thought on how well they model planes vs. flight-test data?
