What happened when you tried the other steps?
As for your dxdiag: I am not able to find any anomalies on there. What I do notice is that you're playing with two monitors. For purposes of testing you might want to disconnect the second monitor and all USB devices you don't use to see if that improves anything.
Since the games still does seem to run fine on your system I don't have much more to add.. if you do have any further questions please let me know.
EDIT:
I posted just after you did your latest post.
The settings that change, are you referring to your BF4 settings? It might change depending on which screen you start the game if both screens aren't the same size as you mentioned.
