Yeah windows 7 compatibility mode seems to do the trick. I changed my launch options to use the 32 bit battlefield 4, and set the 32 bit battlefield 4 .exe to win7 compatibility. I just got done with a very long CQ session (played like 5 maps in a row) with no memory leak.
I though all was well after trying compatibility mode for Windows 7. Things were running pretty good, then suddenly the mem leak issue occurred again. For several rounds on the same server things seemed ok, but then (I don't recall which map) mem usaged jumped and continued until it got to ~95% and I quit before it froze everything up.
I've tried every combination possible. Nothing works for an extended period (hours). Since I can dual boot between Windows 8.1 and Vista, I can say Vista actually does not have the mem leak issue, or at least it hasn't occurred yet. The problem I do have is AMD doesn't support Vista anymore, so I'm playing on old drivers. Before each round, a window pops up telling me to upgrade to the latest driver. The game is playable, but will randomly crash presumably because of the obsolete drivers.
I've come to the conclusion there is no fix other than to wait until EA/DICE addresses the problem.
