DICE has started rolling out a Battlefield 4 patch on PS4 and states it is already working on the next update based on player feedback.
The patch promises general stability fixes which should “remove a large amount of the client crashes” currently being experienced on PS4.
Audio drop outs that could occur when playing on large maps have been fixed, with the typical map affected being Golmud Railway in Conquest with 64 players. Ambient sound would sometimes cut out, “like foley sounds from player running, vehicle engine sounds, vehicle movement sounds, and map ambient sounds.”
DICE also removed the blur effect on soldiers that appeared when Commanders were using EMP attacks and further reduced the probability of getting a corrupt save file by doing miscellaneous changes to the save file system.
These include removing the save file saving again when quitting multiplayer.
Other fixes include: multiple crashes that could occur when bringing up the in-game Battlelog during round transition; a crash that could occur when using the BattleScreen; a random crash related to destroying vehicles; and a fix to minor destruction issues in the terrain have been issued.
The patch is around 600MB in size and you can find out more over on the Battlefield Blog.
