Just at the beginning starting position of the first map I can see that effect already. Just look at the grass, the frozen lake to the left or the big entrance building, or the ledge of the ceiling of the cave you start in:
Ambient Occlusion High, Portals with AO = 2
Ambient Occlusion High, Portals with AO = 4
The grass is much darker in the latter and the other differences mentioned above.
@Nash: I do not have this issue with FXAA, at least not with the latest version.
