Hi,
I did my test yesterday about the server (East vs West). I switched my club to the West server as recommended by the Club settings. The lag was gone. I was finally able to play with my club. I don't know it this would work with everybody, but it did for my club.
Also about the ISP, one of the previous poster is on to something. While I was still on the east server, everybody on my team with Bell Fibe had the lag, but the only member with Videotron did not have the lag.
I don't know what the update changed, but EA must acknowledge there is something wrong and work to fix this asap.
Regards.
