I've taken a look at some of the the hi-res screen shots on site. IMO, in addition to being the best-thought out and engineered combat flight-sim, the planes look pretty darn sweet for anybody with the system to run at high settings.

The hedge-rows and windmills and what have you also look good, a little variety in color might make the terrain a little more pleasant and not hit the system requirements too much...some muddied battlefields, yellow wheat, grey crags, snow-covered peaks, that sort of thing.
