1) panning view somtimes dims overall light, this i can't reproduce but noticed it twice;
2) in first person view look at your own shadow, and you'll see that you are a headless zombie;
3) when going around mountains cast shadows on trees in a weird way, because the edges "move" while you move too, this simply shouldn't happen.
And yeah, I agree about the moving shadows you mention in #3. Looks bad. I forgot to mention those in my post above. I think I even have video of it that I planned on uploading.
