Just checked out the KSFO demo and I've got to say that I am really impressed. Before I purchase though I'd like to say that I noticed some crazy flickering of the grass texture infront of the terminal between those two parking garages. I hope this little issue gets fixed togehther with the allready reported bugs.
I have the same problem with the flickering grass textures. However, this and the missing glideslopes are the only complaints I have about this airport in FS9; it really runs amazingly well even with the large textures and memory usage.
