I have tried to reinstall the game, validating the game files (steam), searched for answer on forums, but onley solution so far is:
Run away from other people, and the Desync problem goes away, untill i get near people again.
I got a good computer and a 100/100 mb internet, and i have tried to plug my internet cable directly to the wall.
I did NOT have this problem before 1-2 days ago
