As this issue seems to have been resolved with new drivers I'll mark this thread as solved now.
I've just answered this post on CTE.
For now, CTE is mainly focused on netcode issues, but there's a better interaction with developpers on the CTE forum since the community is smaller than on retail game forums (and more involved/less whining), so 2 developpers directly answer to the community (unlike retail game forums, that are only read by community managers).
It's a good thing a developper now directly looks into this issue but it doesn't mean he will have time to solve it...especially because there are many memory leaks causes (AMD HD5/6XXX, Realtek sound chips, Windows NDU, ...)
In my case, this solution reduced leak occurences to about once a week in x64, instead of every 2 rounds: http://forums.hardwarezone.com.sg/windows-8-338/awareness-thread-windows-8-memory-leak-ndu-sys-4309046.html
That does not fix the problem, so please go back to the CTE thread and say "This doesn't always work"
BF4 IS THE ONLY GAME THAT DOES THIS
I have about 20 games installed
NO OTHER GAME MAKES MY SYSTEM RUN OUT OF MEMORY
IT IS A BF4 PROBLEM
