Fixed the problem no thanks to the people here, apparently if you turn on "Share usage data" in the EA account settings, it will give you MASSIVE network lag, so turn it off.
this seems to be unccesseary network requests
it seems that actually EVERYTHING is going over network..
you might be able to try it out by youself
- start a big highspeed download
- start the game
then you will experience a lot of lag even in the start menus, because everything seems to be downloaded, which will take longer because f your download you startet before starting the game.
it seems that nothing is cached in the background and already loaded graphics are deleted after leaving views/screens etc.
Something has changed for me in the last few days. The game was smooth as butter in 4K for me ( 2500k @4.7ghz, GTX 1080) then all of a sudden I started seeing other players warping and getting visual lag every 20 seconds or so. I will try changing the EA account settings and report back
