From time to time i get some lag/delay.. not from my connection tho.. my ping is 5 stable (ping google.com -t) . but ingame going from 120 to 1500+ suddenly. Not only me who can sense it.
Or Anti-virus, firewall, some proccess (ctrl+shift+esc and check). Cause servers are working fine .
I noticed exactly the same problem, I even logged my old account on official PW and it was just fine, only here getting lag spikes... same goes to youtube and other games(FPS ones), ping is low and doesnt 'jump', I tried playing on all 3 Epicas. I use a lot of software which keeps my PC clean from infections, it can't be my connection.
