Ive had almost no problems, but that being said my game only runs near to pefect on WIN8.1, latest drivers & some tweaking.
Only real problem is I sometimes cant connect to certain server but that seems to be server side, take a look at this vid:

Frame increase from WIN7 to WIN8 is just crazy.
Frame increase from windows 7/8 to 8.1 is also high. Recommend 8.1 for bf 4 without a doubt. The latest .net is included in windows 8.1 and offer huge improvement in bf 4.
