DICE say that its latest patch for Battlefield 4, released yesterday, can reduce delays from server lag by more than half for players with a fast internet connection.
The patch (full notes here) adds an option for high-frequency network updates, which create a “high frequency bubble” around the player resulting in reduced delays within that radius. I’m not sure how it all works either, but luckily DICE have released a new video explaining what they’re talking about.
The high-frequency network option is switched off by default, but players with a connection greater than 1mbps are encouraged to use it; DICE say they’ve found it reduces close-range delays by up to 60%.
”This is the first release to contain CTE-tested “Netcode” fixes and improvements,” reads the update’s accompanying Battlelog post. “We are still hard at work with additional improvements and tweaks to better our network experience that did not make this release.”
