I have 33 fps and I am disappointed about the dynamic shadows. Why don't you blur them? I saw this jitterish salt also in GTA4 and it just looks silly (I don't blame you, I just wonder why you didn't blurred it because it is obvious that it is striking).

Could you please add a hotkey to toggle SSAO? Since I am working on the same topic, I would like to look into it a bit more what works for you and what not.
