Packet loss issue

Do you have some details about your ISP and your internet hardware for us?

At first, download and install the latest version of Origin at www.origin.com/download (and make sure you have your Origin account ready as well)
If that doesn’t helped, close the origin client and go directly to you origin folder  C:\Program Files\Origin Games. Run the origin.exe in this folder with a rightclick -> run as administrator. 

Try to deactivate your firewall/antivirus software and/or check the online ports of your connection:

TCP: 80, 443, 9988, 20000-20100, 22990, 17502, 42127
UDP: 3659, 14000-14016, 22990-23006, 25200-25300
For specific instructions on how to open your ports, please visit http://www.portforward.com/ or contact your router manufacturer.

Please let us now, if this problem after this workaround still exist.

After much research into a fix for this issue and many hours spent trying to find a issue on my side ive come to these fourms to bring this problem to light. Allot of people dont even relize they are getting the same problem (some worse then others) but its all packet loss with BF4. I have found tons of posts from players haveing this same issue on multiple continets in diffent countrys. The only similar factor is BF4.... I have swaped modems(i dont use a router) ive taken my comp to buddys and used thier ISP ive done ping tests and loss tests ive even swaped my network card. I have a beast of a gameing PC built just to play BF4 on ultra with steady frames. ive disabled firewalls and scanned for virus's and unistalled and reinstalled i have posted on forums with no1 able to provibe answer only to hear echo's from other people all over the world who have done just as much with no fix who are haveing the SAME issue.

All the servers i play on are sub 30pings and are in the USA  (im midwest) all i can say is its on your end EA / Dice search your own forums and you will find tons of posts with this exact problem the de sync icon contuially pops up and in my case there is a slight lag that comes with it...it does not render it unplayable but it is noticable and makes flying the heli even worse then it already is...
