As this issue seems to have been resolved with new drivers I'll mark this thread as solved now.
Thanks for the thread, carbonic!
After the Dec 9th-Patch the memory leaks seem to have gotten even worse for me. Yesterday, it happened three times in four hours of playing. I cannot make out a specific line of events that leads to the leak. Sometimes it happens on the first server joined, on the second map or so. Sometimes not until four, five, six servers and several rounds. Also no specific weapons/classes/modes/maps etc. Completely random.
Tried the Network-fixes mentioned on Reddit, didn't work. Tried Compatibility-Mode, didn't work, rolled back to Catalyst 13.11 Beta 8, didn't work. Changed the NonPagedPool-Size in the Registry to 256, didn't work.
My configuration:
Windows 8.1 x64 (Windows update runs automatically)
Radeon HD6900
Intel i5 2.500k @3.3 GHz
16GB RAM
All the Catalyst-Beta-drivers since the BF4-Release (Beta 8 up to 9.5)
Nothing overclocked or otherwise customized.
