* I have a problem where fire in Skyrim "integrates" (don't know the right word) with it's background, making everything behind the fire shake in the same way as the fire. This is most easily seen in camp fires.
* Also, above my spell hands there is a curved line you can see in this screenshot: http://img593.imageshack.us/img593/2664/screenshot3ey.png. It's hard to detect but it's there and it's more present in-game and annoys me.

For the curved line try setting AA to 2 or 4 (or off).
