I have downloaded the X-Plane 10 demo lately.
All I can say is -- WOW! The dynamic lighting makes flying the night scenes so realistic! This, combined with the cars moving about on roads, it looks just like when I'm on a real plane, looking down towards the ground. Austin Meyer, founder of Laminar Research and maker of X-Plane says in an interview that the roads are based on OpenStreet Map, and based on that street map data they auto-generate the buildings and roadways in the sim. The effect is wonderful - even though the city we're flying over won't be exactly the same, the the sim loads up buildings in what it thinks are suburban areas and cities and place buildings accordingly. That means roads near a waterfront will have waterfront houses, densely packed areas will have tall buildings, etc. It is a wonderful result.
The dynamic lighting also makes the sim realistic, how the lighting looks depends on time of day, and it is dawn or dusk that is especially interesting, especially when all the light on the aircraft comes on, and all the city lights and cars went on.
The clouds are even better, never have I seen so convincing clouds in a sim yet - like in real life, you can have cloudy areas in one direction and clear areas in another direction.
The sim does have some problems though - if you treat it like a game, then it will be like a toy. For example, most obstacles and buildings don't have collision detection, you just fly through them. Landing on water, you will just float like a child's bath toy. You can even take off again from water....
But ultimately, we don't get simulations to do things such as those, we use simulations to fly, and the planes provided that I tried so far have been great.
Needless to say there are a lot more things to write about X-Plane 10 which I don't have time to (I'm working as I type this!) and it is my latest interest so far- other than Kerbal Space Program, and FlightGear of course.
The simulation runs quite smoothly in default settings on my late-2012 Mac mini. The demo will disable joystick input after 15 minutes.
