I regularly have missing textures, losing heads and hands of NPCs, trees that are purpleish and walls that you can see through. Few instances of being able to walk though ore veins into the void.
Also I didn't get the last word of the shout firebreath, when I read it on its wall, just doesn't appear, but does like enter your soul with that magicical stream.
Also I dislike the fact that many quests cannot be continued if you not finish other quests, like if you do not go to Svongarde in main quest you cannot delliver a letter from Imperial Legion, etc.
I have more frequent CTDs after the the forced using of steam, without it the game is tenfold more stable.
