no you have lag spikes. no one in game has their ms fluctuate at all its a stready 100 to 180. Your connection is not strong is why.

Im getting this problem too for games 3vs3 and above and its really annoying. It was much worse in the other patches(unplayable) but now it is playable but other players in the game get mad at me and complain. Of course the generic answer to this problem is "your internet sucks", "turn off antivirus, torrents, firewall, foward ports, etc"....but I have done all of that.

Explain how I can play 4vs4 games in Company of Heroes just fine but not in this game? They both are p2p correct?

There seem to be three kinds of lag spikes also:

The ones where the game starts slideshowing, but still moving forward. This is the traditional "someone's ping just shot up"

The ones where the game completely stops moving for a little while, but you can still type messages and people can chat.  No idea why this happens but it occurs every couple games.

And the ones where the connection window pops up and someone's timeout time starts increasing.  This happens whenever someone leaves but I've also seen it happen and the person who was lagging recover and the game continues.  Also don't know what triggers this.
