Ever since Battlefield 4's launch, the multiplayer has had several issues, being one of most troublesome the rubber-banding, which became more persistent with the release of the "Naval Strike" DLC. With the idea of at least reducing the effects of this issue, EA has announced that server upgrades have been rolled out for the title.
The producer had revealed earlier this month that it was not satisfied with the current condition of the multiplayer, specially regarding this issue. The server upgrade has been through a lot of testing to make sure that it actually fixes the issue without adding a few others along.
"While the process took longer than we would've liked, we wanted to be 100% sure it was done right and that the long-term solution was properly in place. Our objective is to deliver the best player experience possible. We feel this solution helps us deliver that to you. Stay tuned to our official channels for more information," said Karl Magnus Troedsson, DICE VP & GM.
