Things have a pretty surface but seem to be made out of empty paper..
1. 'Floating trees' in the foreground explained.
- The sun is shining.
- Buildings cast shadows on other buildings.
- Trees do not fully cast shadows. They seem to cast something but seems to be the center trunk + something thin.
Ground objects lacking shadows in a sunny environment gives impression that they are not standing anchored on the ground. EDIT: Can see in the other screens posted above that they fully cast shadows, so certainly it is just a graphic setting.
2. The cockpit in the Heinkel and the Beufighter(?).
The reflections on the fancy instrument dials appear to be missing so it is probably a lower graphical setting.
3. Crew animated.
Exciting! Makes a large difference for me in the appeal for flying non-fighter planes. Physics and animations is what is missing more than anything else in 3D games since a very long time ago. Hope to see this sort of effect on the own body rendered in first person view at some point.
