Hi, i've been getting very high packet losses and latency variation on some servers in Battlefield 4. On some servers it's fine and latency variation is never >2ms, but on some RecvRate drops from 60hz to 20hz and then the packet losses go up instantly to 80-100%.I tried these things:- turning off firewall- forwarding ports on router- restarting modem/router and PC- changing the DNS- turning on bf4 as administrator- veryifying game files- reinstalling the game- launching from clean boot.I've played some Battlefield 1 and V, and this problem doesn't occur there on any server. I also don't have problems in any other game.There are 3 screenshots with netgraphs from lagging server, non lagging and a speedtest result.

Hi @CantM0ssadAssad You actually do not need at all all that amazing download/upload speed to play the BF game. Too high a net speed is often even antagonistic to obtaining a perfect line quality which you need for good gaming experience. First sign is exactly the constant rise of retransmissions of data packages, which then in next stage will result in package loss when saturation happens on either end.For the BF4 game you only need around max 3-4 Mb/s download and around 750kb/s in upload. Anything faster than that is not even used. As the ISP is often focusing on bragging with their high speeds, the compromise is on the line quality. And that means everything for your gameplay. Bette to turn down the speed a bit while then recovering the ability to consistently having a perfect line quality for your FPS gaming. So having a fast or a super fast line brings you absolutely nothing to your gaming here in this game. Even on the server you list with heavy package loss you have a latency of 160ms to that server.That would normally not be any problem at all, though one could argue it should ideally be lower. Anything below 180ms appear to be the magic border for still working ok for the game and experience. Above 200ms it starts to become noticeable bad. But the extreme package loss is of course a total game stopper!Even just a small level of package loss like just 0.1-0.3% is bad for your gaming experience.To find out where the problem is then please use the TraceRoute tool that EA promotes on the Help screen for connection issues. Here you see the route your data packages needs to travel from your game platform to the BF4 game server. And the response from each node along the travel will be listed in that report. This will tell you then if the issue is on your end, at a certain node along the travel, or if it is at the server hosting destination. Depending on the result of the findings, you know then where to go next for fixing the issue. I got my own line speed reduced by 50Mb/s, and after this I now almost never have any 'you lost connection to the EA server' situations, while before it was like several times during one evening. You only need like 25 Mb/s to watch a live 4k Ultra HD movie on Netflix, so think about what is really the key priority here, as more of something is not always better.@bishtop ,Your observation is actually very classic. And the lag you experience is not caused by you/your own apparently good line connection. The root cause is actually the many other players that are on the server where some obviously have poor line quality and package loss. Your local game platform is quick to send/receive all needed updates to your screen and the game server, but it halts as its still waiting for updates from the server that is pausing to wait for the updates coming in from those high latency/high package loss players also on the server. We have done some tech testing and identified that even just 1-3 of such players (aka latency above 1200ms and 0.2% package loss) on a 64 player server can bring it down to its knees. And everybody else on the server are troubled with the constant lagging and rubberbanding. The servers even crash in the end as result if sustained load from those high latency/high package loss players! Funny also that you observe this especially on a Locker server you mention. Because we have also identified this specific problem for the servers to keep up with high-latency players on board is especially challenged when many players are in close proximity on the map (you may be aware as well about how the visionary field and game mechanics are more detailed and more frequent calculated, when in near space versus far space between soldiers). And it is especially the flares and smoke grenades that appear to be the most demanding for calculating/updating the screens/game mechanics for everybody. Probably because every single particle in those weapon types generates a broad specter of changes for each and every single soldier in the game. We have tested and found especially the Locker and the Metro maps being the maps where this is most extreme and measurable. Sanitation to avoid this is unfortunately that the server admins needs to kick off such players with poor line quality and/or very high latency.Doing this however, makes the game play and experience great for all the 64 players that do come onto the server then and you also avoid all the server crashes that we otherwise observe so many are suffering from. Hope this info was of some help to you.

Hi @bishtop ,When hardware offloading is 'ON' then your CPU will offload the processing of network tasks from the CPU to your NIC !If your NIC is up to it, then it is definitely the way to go, as the CPU is typically the main bottleneck for the interactions with everything you have attached to your PCI bus. (when running a system perf test, while gaming, you should get a good insight into if your CPU is challenged in current setup?). If so, then by offloading, you will typically see great improvements to both the generic tasks completion and also your local network latency caused by your PC!The NIC is specialized to handle the load of processing network tasks better than CPUs, though of course not all NICs are equally good... But if you have a decent PC and its components are of same generation, then I would always by default run with offloading ON.Best of luck with this nerdy stuff. :o)

@bishtop You can also try a fixed DNS, Google fixed DNS, and set a fixed DNS like 1.1.1.1.. This sometimes will smooth connections out a little.Might want to flush DNS also. At the CMD prompt type "ipconfig /flushdns" without quotes, this will clear the DNS, Type "exit" to exit CMD

If your ISP allows it, then always strive to have to two different ones (providers) and not linked to your local DNS. Another helpful feature is to setup your onw local router to always 're-initialize' once every 24 hours. This way you also flush its IP and routing buffer, so its always keep up to date and clean. Many routers also suffer to some degree with handling the buffer overruns when their mapping tables are fully filled up and they need somehow to prioritize which to overwrite or not...Certainly your great Qualcomm Atheros network adapter card that you have @bishtop should have no problem at all to handle all the processing and serve your gaming needs here for both BF4 and also the future BF2042 game. So its all about keeping your driver up to date and get the settings optimized to make it all work best possible for you.

First of all , id like to say thanks once again for the information, love to learn stuff more indepth. Id left my router switched off over night and today when turned it on i had a new IP address which someone had told me to try, i didnt expect anything to improve but for the moment it kind of feels better. To early to say the improvement is not just in my head though. Fingers Crossed :D
Take care man

Great direction @sk1lld !

Thank you, Now you've mentioned it i (Just about) remember someone telling me years ago that DNS is the one thing that people overlook and dont check when they try to troubleshoot issues, il give this a try for sure.
I have just checked on my router and it has the option in the attached picture, il see what i can do with it.
Appreciated 🙂

Thank you sk1lld, Its great to see two members that help others without going down the route of trying to blame a persons lack of skill ect (trolling). Both of you have been a great help and if anything i forgot how much "Fun" (can tell i live a boring life :D) it can be to problem solve by learning and relearning.
Thanks and respect to you both
