Since the begining of August or since the update Uplay, PC gaming assassin's creed revelation multiplayer heavy lag.
Firstly the "synchronization of your saved games with the cloud" takes a long time or does not work.
Then there is this repeated message "the network is experiencing technical problems, please wait".
Thus I opened the ports of my livebox as explained, Ports ACR: UDP: 21200, 7959, 3074 - Lanceur Uplay: TCP: 80, 443, 13000, 13005, 13200 – Trophées UDP et TCP: 14001.
I reduced my game configuration and remove shadow quality characters etc......
But it makes no difference.
I'd like to know if other players have the same problem on PC.
