As this issue seems to have been resolved with new drivers I'll mark this thread as solved now.
Seems like SOMEONE has finally GOT it. Battlelog forums page says "WE ARE WORKING ON A FIX FOR AN ISSUE ON PC THAT CAUSES THE GAME TO FREEZE, RESULTING IN A SOUND LOOP. WE WILL SHARE MORE INFORMATION ONCE AVAILABLE." 😉
Got both bugs. Soundloopcrash on Metro (cant play more than 20seconds) and NPPMemoryLeak
I have 8g of memory and when bf4 game for a while begins to pound the memory of the PC. I know this because the doll is slow and lowers the fps of the game affecting performance and becoming unbearable to play. then in device manager before the game wore on average 3GB is already using 7.3 Giga of memory. Fix this DICE.
Windows 8.1
Asus M4A79T Deluxe
8 GB Ram
ATI Radeon HD 6950 2GB Saphire
HD Samsung 250GB SSD
Really annoying... New computer.. And yesterday AND some days before tonight, I did not have this problem. Today, all my memory gets eaten... And need to shut down the computer to set it free.
