DICE said earlier this month that it planned to upgrade Battlefield 4's servers because it was "unhappy" with the performance as far as rubber-banding was concerned. The recent release of the game's Naval Strike expansion seemed to exacerbate the problem, and according to DICE, the root cause was "a configuration of certain hardware types dedicated to 64-player matches." Only the PlayStation 4, Windows PC and Xbox One versions of the game support 64-player combat.
This week's server upgrade is aimed at fixing the rubber-banding problems. DICE said today that it did a lot of testing before rolling out the new hardware to make sure it actually addresses rubber-banding, and that performance is already improving as a result of the new servers.
"While the process took longer than we would've liked, we wanted to be 100 percent sure it was done right and that the long-term solution was properly in place," said Karl Magnus Troedsson, vice president and general manager of DICE. Last month, the studio indicated that fixing Battlefield 4's netcode was one of its "top priorities." For more, you can check out our full review of the game.
