First of all, forgive my very poor English (I'm Italian, I'm trying to learn! ).
I recently bought GTA Complete Edition on Steam, although so far I have only installed the base game (GTA IV).
From the first day that I own the game, I find myself unable to access the multiplayer, especially the games with a lot of people. If I try to connect, it shows the message "Disconnected from game session", returning to single player.
I can connect to games with 2-3 people, maximum 5 if they are in the waiting room.
My NAT is open (based on information as Games for Windows) and the ports on the router are open. I also tried to disable Firewall and Antivirus, without results.
I was also recommended to disable the graphical quality because the problem could be caused by the FPS, but the minimum quality problem will occur.
Is a very annoying problem!
Does anyone have any solution? Thanks and regards!
