Aerofly FS2 has some of the most realistic imagery and appearance for any flight simulator - especially in VR (as well as smooth performance!!!). There is one concept that I haven't noticed being used yet that I have seen in War Thunder that really adds to the looks of some textures on roads/taxiways/runways/terrains - bump mapping. It also helps with the rivets on the plane's wings. I like to fly low above the ground (please add a heli soon!) and bump mapping helps make areas really look great.
Thanks for such a wonderful flying experience!

P.S. Could you provide some palm trees for Southern California
