Seems that steam sales is causing some unexpected performance problems.. Right now I cant join any multiplayer, lobby never end loading and the few times i was able to load something it is full. Seem that there are so many games that it consume all my bandwith just with that. my internet connection, good enough I guess and PA during lobby (note that orange line is PA) any one has the same problem? please help!!
Very similar problem. Bandwidth usage is very high, long login times and multiplayer games list never loads or ends in a "Cannot retrieve game list" error. But inviting works alright.
Same, was able to play 4 to 5 hours ago. Just tried to play and fails after a bit on the lobby, while using a lot of bandwidth.
