As this issue seems to have been resolved with new drivers I'll mark this thread as solved now.
I can also confirm that the problem still persits after upgrading to the latest AMD drivers: 13.11_betav9.5 (12/3/2013).
But alt+tab usually works for me, much better with China Rising but yeah, also memory leaks there.
Running AMD HD6850.
I have been frequently suffering from this issue. Sometimes I can play no more than a map or two following a full restart without encountering it.
Won't be a problem much longer as I have a new non-AMD card on the way. Tired of waiting for a fix. That said, I used Poolmon.exe to find the tag for the item that was taking up all of the space in my NP virtual memory. The culprit was the MINI tag which traces back to atikmdag.sys file, which is a file associated with the AMD driver package. This corroborates what another user found here using the same tools: http://forums.guru3d.com/showthread.php?p=4689663
My specs are as follows:
AMD Phenom II X6 1090T 3.20 Ghz CPU
8 GB RAM
Windows 8.1 64
Radeon 5770 CPU (for a couple more days)
1 TB available HDD Space
Windows Managed Virtual Memory (still occurs even if I set VM to a fixed size)
Also, I just for the second time today had this occur within a map and a half of play after a fresh reboot. Not sure if it is related to the maps specifically, the server (was same server both times), or number of players on the server. I typically play on 30-32 player servers but both instances today were on a 64 player server (full), and in both cases the first map was Gullen Peaks followed by Silk Road.
Just happened again to me for the third time today. Again after a fresh reboot, was able to finish the round of Obliteration on Operation Locker that was in progress when I joined, got all the way through a round of Siege of Shanghai, but then about 10 minutes into Lancing Dam I started experiencing the tell tale signs that the leak was back.
I opened up Task Manager and my Non-paged pool was at 5.3 GB. Hard Disk usage was at 100% as Windows was pounding my virtual memory. I managed to get BF4 to exit (took a long time as my PC was mostly unresponsive at this point) and was able to run PoolMon.exe again. Again the culprit is the MINI tag with 5,501.351.840 Bytes allocated (non paging).
As I type this, task manager shows 7.6 GB "In Use" with only Origin and Google Chrome running
I'm also experiencing this. It's extremely annoying.
PC spec is:
i5 2500k
P8P67 Pro motherboard
8Gb RAM
Asus 5850 with latest 13.11 beta 9.5 drivers.
Windows 8.1
There doesn't seem to be any pattern to when it occurs, only that after I play a few maps, RAM fills up and it starts swapping to disk like crazy.
I have done a couple of thing, now the problem is gone.
BF4 in Win7 Compability mode
CCC.exe in Win7 Compability mode (this was a key factor for me)
Disbled NDU
Updated Realtek Ethernet drivers.
Memory rises to about 4.5GB when in game, and then releases 700MB down to 3.8GB, and the following map is goes up again to 4.5GB.
Solid as a rock now, but i noticed some loss in FPS, and some less smoother gameplay with this fixes.
NP is around 112-116MB constantly
Paged pool around 250-300MB.
And when i exit the game the system hogs around 2GB of memory..
Radeon 6970
8GB RAM
Intel Core i7
Running on Win8 all patched but not upgraded to 8.1.
Probably i have done more than i tell here, but nothing that i can remember right now, many late hours cursing over DICE/EA/AMD and reading forums and trying to fiddle self.
