I find I keep stopping while walking. It's like I keep getting hung up on things in my way. I'm using a wired controller so that isn't the problem. It started happening when I patched to 1.3. This is on Xbox 360.

Is this happening to anyone else?

It is happening to a friend of mine as well it tends to be an issue with the game something that might have to be patched out... you should check the hardware and software issues forum for skyrim for your platform you play on for more info.

Well the stuttering stopped after awhile. I think I completed a quest and all of a sudden it was fine again.

Clear the game cache by holding bumpers and x during the boot

I had this problem..believe it or not I had my wife delete some of her huge number of save games and it took care of the probem...doesn't make alot of sense but there ya go.
