laggin in offline

major lag trying to play offline matches so inconceivable how in any circumstances this is possible, i know how to use google so thanks to everyone who trys to give the exact same suggestions as everyone else in advance. drivers are up to date. firewall is off, ea whatever is off, lowered the player count lowered the setting. nothing works because it EAs fault not mine. evidence is that i can play the campain without issue and online matches arent half as bad. i just want to play offline instead of waiting for matches on a game i paid for and waited an over an hour to install that takes up 90gb. without connection lag. it even gives me the bad connection signal that may itterrupt gameplay or whatever. THE WIFI IS LITERALLY OFF HOW IN TF IS THERE A BAD CONNECTION ITS OFFLINE
