The "high performance" server upgrades promised for Battlefield 4 earlier this month have been deployed as of this week, EA DICE today confirms. Battlefield 4's online multiplayer experience in large-scale matches hasn't exactly garnered a sterling reputation since the multiplatform title's launch half a year a ago, with latency issues lending themselves to "rubberbanding" that once again emerged after the recent release of the Naval Strike DLC.
Rubberbanding (where it appears you're moving forward before you suddenly find yourself a few paces back) was the main issue DICE hoped to fix with the upgrades. DICE determined the root cause lay in the certain configurations of hardware it originally dedicated to handle 64-player matches. The server upgrades are intended to replace the unoptimized hardware, and DICE pledges it has thoroughly tested the replacement gear to ensure they actually address rubberbanding.
The studio acknowledged in the Battlefield blog that it took much longer to than expected to implement a solution for the ongoing problems which other major releases from publisher EA managed to largely avoid. That said, DICE seems convinced it has finally hit on a solution with "performance improvements" evident in 64-player matches by its reckoning.
