The Battlefield Blog has word on DICE's promised efforts at addressing rubber-banding and other latency-related issues in Battlefield 4 that followed the launch of the Naval Strike DLC for the military shooter sequel. Word is they have rolled out some new hardware:

As you know, we’ve been looking into resolving the “rubber banding” that some players on certain platforms have experienced with Battlefield 4 after the recent release of Naval Strike. We’ve found that the root cause of the issue was a configuration of certain hardware types dedicated to 64-player matches.

We have invested in new hardware to resolve this issue and deployed new higher-performance servers this week. In preparation, we conducted a significant amount of testing before installing the new servers to ensure they would correct the issue. We are already seeing performance improvement with 64-player matches and expect this to continue.

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.
