Sorry, no FS9 shot, since my FS is
always running with AA & AF (game profile).
So I just took Racer (free car sim).
No Anti-Aliasing, no Anisotropic Filtering.
Note the jagged edges of the car's windows and lights and the building's roof.

4*Anti-Aliasing, 8*Anisotropic Filtering.
While there's no effect on the track's surface (might be an issue with the game engine, all kinds of edges on the car (lights, windows, etc...) and also the building's roof are smoothed out. Also note the smoother track map.

No comment on the sim, if you're interested, use Google.
