Here is the release notes for Battlefield 4 on the PC that also fixes the so called “kill trading” issue. This patch also fixes a list of other bugs related to sound, gameplay and overall stability.
Also Dice says that it is investigating issues related to ‘graphical flickering’ on SLI-enabled PCs, and the revive bar getting stuck on-screen
Dec 16 PC Game Update Notes
-Fix for a crash that would cause the game to stall, resulting in a sound loop. This should eliminate most of the problems relating to this.
-Fix for the SUAV (introduced in the China Rising expansion pack) not exploding when hitting enemy soldiers. While these indeed should be deadly, they were never designed for “roadkilling” opponents.
-Fixed one of the issues related to the so-called “Netcode” (see below for details).
-Fix for an issue where 4x the damage from a vehicle’s minigun would be applied to the chest when a player had the Defense specialization equipped.
-Fix for player tags not always showing when needed to, resulting in players shooting team members.
-Fix for graphical flickering appearing on terrain.
-Fixed the instance where players suddenly would transition into Spectator Mode while playing the Defuse game mode.
-Fix for a Defuse bug where none of the teams would win a round by letting the timer run out.
-Fix for players getting stuck in the revive screen after being killed.
-Fix for players getting stuck in the kill camera after being revived.
-Fix for the game mode specific ribbons being counted twice in the multiplayer progression.
-Made NVidia 331.82 or later driver versions mandatory for all players.
-Disabled DirectX 11.1 on NVidia cards that have outdated drivers.
-Fixed driver version not being properly detected on NVidia Optimus systems.
-Fixed a minor crash that could occur when bringing up the scoreboard.
“Netcode” improvement We’ve addressed the so-called “Kill trading”. This refers to when two players fire at each other and, seemingly, both die at the same time. The time window where a bullet could cause damage from an already dead player is now calculated as intended, decreasing the timeframe when players with high latency could get a kill, even though they should be dead according to the server.
