EA recently posted an update on the newest patch for Battlefield 4 on Battlelog. The patch is supposed to help the multiplayer netcode for the game and is detailed below.
“We’re happy to announce that we’ve released an update for PC, PS3, and X360 today containing the new improved “Netcode” for Battlefield 4. The update will be released later this week on PS4 and Xbox One.
This update has been developed using the CTE (Community Test Environment) on PC (you can sign up if you haven’t done so already at http://cte.battlelog.com), and is the first update being deployed using your gameplay feedback.
The number of changes possible in this update would be difficult to pull off without the continued support from our community, both through direct constructive feedback and telemetry data gathered on the CTE.
High Frequency Network Update
For the PC, PS4, and Xbox One platforms, we are adding something we nicknamed the “High Frequency Bubble”. Within a certain radius of the player, we add the possibility to update the clients at a higher rate from the server. What this essentially means is that the server will update the client on what is happening more often than before. This normally results in a smoother, more “correct” player experience.”
