However not everyone is experiencing this, I know i haven't for a while... (still an issue for some)
You have to give DICE some credit for being proactive at resolving this issue: LINK
What we have Fixed
Kill card shows 0 health
Kill card sometimes incorrectly displays 0 health, despite the enemy being alive. This could happen when a portion of damage dealt was rejected by the server, since the bullets that caused it were fired after the point of death for the firing player – the kill card would show the health as predicted by your game client, rather than the health confirmed by the server. An improvement that decreased the rate at which this happens went live for PC on Feb 13, and will be included in the next game update for all the platforms.
We have fixed instances of broken collision that made it impossible for players to shoot past broken objects, such as the collapsed chimney on Zavod 311.
Crosshair disappearing, resulting in hit markers disappearing
In firefights, players on PC could experience their crosshair disappearing, resulting in hit markers also disappearing. This would happen when certain gadgets were deployed by other players. A fix for this is now live.
Hit impact sounds
Impact sounds did not match the number of bullet impacts, causing players to feel that they died too quickly. An improvement to this went live for PC on February 13, and will be included in the next update for all the other platforms. The cooldown time for letting bullet hits trigger the sound has been decreased considerably, so players will now hear every bullet that hits them.
We have re-introduced the headshot icon to help players understand when they get killed by a headshot, something that usually results in an instant death. The headshot icon went live in the January 30-31 game update for all platforms.
We want to assure you that we are constantly investigating, or already in the process of updating, all these items and several more that you’ve had concerns with – and that we will continue to do so with your help. Please continue to send us your feedback, and thank you for your continued support.
What we are Fixing or Investigating
We have made several server optimizations that have decreased rubber banding for some players. To further address the issue, there are upcoming fixes for packet loss and a customize screen bug, both connected to the rubber banding issue. Furthermore, we will continue to collect data to pinpoint exactly when and why rubber banding is occurring.
Kill camera delay / Player death sync
On some occasions, the kill camera would trigger before the game client displayed the last portion of damage being dealt, giving players the impression that they died too early. There were also issues with blood effects, damage indicators, and the health bar in the HUD being out of sync. A fix for this will be included in the next game update.
Players have been asking whether the tickrate – how often the server will update the game world – in Battlefield 4 will be higher in the future. Though we haven’t got any immediate plans to increase the tickrate at this moment, we are exploring the possibilities of raising the tickrate on specific servers.
No registered damage
We are aware of the bug where players have been firing at their opponent and not doing damage. In the February 13 game update for PC, we added a piece of code that enables us to specifically track instances where this would occur. We are currently looking at when this issue is triggered, and what causes it. The data that we receive will help us to further improve the firefights in the future.
Instant death while sprinting
At certain occasions while walking or sprinting, a player could get catapulted at high speed which would cause death if any object was standing in the way. This was caused by a mathematical error in the character physics code, and we have a fix prepared for an upcoming patch.
In addition to these items, there are also fixes coming for issues with Levolution being out of sync, shots appearing to be fired in the wrong direction, and vehicles outside the infantry area not taking damage when fired at. Also, we have introduced new in-game icons that will help you, and us, to troubleshoot network related problems that could cause an inconsistent multiplayer experience.
Network Troubleshooting Icons
With the January 30-31 game updates, we’ve introduced two new icons to the Battlefield 4 HUD (head-up display). These were added to the game as a way for us, and the players, to more easily troubleshoot common network-related issues that may have negative effects on the multiplayer experience.
Bottom line for as popular as this game is, imagine the challenge they have trying to cater to an abundance of system configurations from low end barely playable specs (People can be stubborn or not know any better) down to GOD tier systems and probably some crappy internet connections with terrible latency...Edited by hyp36rmax - 3/4/14 at 1:55pm
