I'm also having issues with this. The weird thing is, my friend and I are on the same internet connection (lan party), we both have almost identical specs for our computers and we're on very fast (50mbps) internet at my house. He hardly ever has this issue and I have it almost every game. I think I've only had 1 or 2 games where it didn't happen. I've tried having him connect to the internet first and I've tried having mine connect first, still always has this problem. I don't get it. Kinda ruins the game when you lag out when trying to chain jumps together or lag out while in a big firefight.
