There is a bug in screen battle menu with ironborn's raiding parties in the north and you can't fight them, you just can "leave".

There is some graphicals reflects on faces especially the night. Trees are waving/moving too much.
Also i have noticed saves problems like if one on two saves were forgotten (need confirmation of other players).
Should be fixed now.
For your other issues try turning off HDR.
