With many of the issues causing Battlefield 4 to crash on PC largely a thing of the past, DICE is now focusing on fixing a few items based on feedback from players.
"Specifically, we are looking at the Commander EMP blur effect that you have noticed, as well as the intermittent sound bug that happens most frequently on the Golmud Railway map," DICE said on Battlelog. They are still looking at increasing the game's stability overall, as well.
DICE is also looking at a "1 shot kill bug," which was brought to their attention by YouTuber Jackfrags. "It looks like weapons sometimes deal too much damage (although the real issue might be more complex.)," DICE said. They are currently reproducing the bug and working to fix it as soon as possible.
Unfortunately, the developer could not offer a solid release date for the patch, but we'll be sure to keep you updated once they do.
