I did not switch AA on. I am running on Vista 64 with lots of memory and Core 2 duo. But on my old machine it was the same behaviour. The shadows do not flicker very much, but they do, similar like in TombRaider Underworld.

Camera is smooth in demo mode, but not in free camera mode.

The models are not high-poly. The renderer is not optimized and scene management is weak, especially when you are in the middle of an island.
