Peer to Peer MMO

To connect with other Dungeon Fighters, DFO uses what is called a Peer to Peer system. This means that while you're in town, the game server is what you are connected to, but once you enter a dungeon, you are connected to the Party leader. This vastly reduces the strain on the game's servers, but causes a couple of problems when partying.

When you start a party, you're computer will attempt to 'sync up' with that of the host and the other party members. If one person has trouble syncing with another party member, lag will occur in dungeon.

The worst form lag can take in DFO is a frozen monster. When one person in the party cannot correctly sync with the host, but syncs with everyone else, monsters will become unhittable and immobile, frozen, which stops the progress of the party and is generally annoying. When this happens, if you see that you are the person lagging with the host and causing the freeze, it is polite to leave the party, so they can continue on.

DFO provides a connection indicator on party members' portraits, so you can easily tell if you're syncing with someone or not.
