Ever since the Battlefield 4 expansion Naval Strike launched, some players have noticed a weird server glitch in online play where players teleport around the map. DICE has addressed this "rubber-banding" error with new "high-performance servers" it introduced this weekend.
A statement on the Battlefield blog from bossman Karl Magnus Troedsson reads: "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."
So far, though, everything about the performance of Battlefield 4 has been unpredictable, so watch out anyway.
