DICE has listed the fixes included with the latest patch for Battlefield 4 on PS4 on the Battlelog.
You'll need to restart the game in order for the patch to be installed. The fixes are:
- General stability fixes that should remove a large amount of the client crashes we are currently seeing on the PS4
- Fixed the audio drop outs that could occur when playing on large maps. Typical map affected was 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
- Removed the blur effect on soldiers that appeared when Commanders were using EMP attacks
- 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
- Fixed multiple crashes that could occur when bringing up the in-game Battlelog during round transition
- Fixed a crash that could occur when using the BattleScreen
- Fixed a random crash related to destroying vehicles
- Fixed minor destruction issues in the terrain
The issues which have affected Battlefield 4 since launch have caused DICE to suspend development of all future projects, including expansions for the game, in order to resolve the problems – this led to a brief but significant plunge in the value of EA's share price.
Today it was revealed that EA is being investigated by a law firm for potentially misleading investors over the quality of Battlefield 4.
