After weeks of testing in the CTE (Community Test Environment) the Battlefield 4 “netcode” improvements are being rolled out to every version of the game today in a patch according to a new post on Battlelog. The “netcode” patch improves (among other things) the server tick-rate, or how often you computer receives new information from the server. Battlefield 4 previously had a tick-rate of 10hz, or ten updates a second (industry standard for FPS games is 30-60).
