 | | kevindqc on Jan 6, 2018 | prev [–] Are you sure? I would be extremely surprised if it wouldn't use UDP. For things like getting stats, probably from a HTTP endpoint, sure, but for gameplay? The lag would be very bad, no? Lose a packet and everything is slowed down I see this, which indicates it uses UDP:https://imgur.com/al6KTwT and according to wireshark it's used heavily when in a game, so I assume that's the gameplay protocol. Also when I left my game (but stayed in the lobby), immediately the port 61879 stopped listening. I'm not sure about UE4, but previous versions of the unreal engine used UDP for replication and RPC. |
FAQs
Does fortnite use UDP or TCP? ›
Fortnite doesn't use UDP at all (80, 443 and 5222 all TCP), UE4 uses TCP for its network stack by default. Nope, it might use TCP for negotiation of things that aren't time sensitive but it uses UDP for replication[1] as has pretty much every Unreal or Quake based engine since they were first developed.
Does UE4 use TCP or UDP? ›Unreal Engine uses UDP (User Datagram Protocol) for communication throughout the internet. This protocol is specifically chosen for time-sensitive applications like gaming or streaming because it is more lightweight. Packet headers acknowledge packets to be retransmitted in case they are lost.
Is gaming TCP or UDP? ›Fast-paced multiplayer games (first person shooters, arena games, etc), use UDP protocol to sync player movement and update game state. UDP headers are ideal for sending these game updates at a ridiculously fast speed, but messages are not guaranteed (because the next message is coming so fast behind).
Does Fortnite block VPNs? ›Fortnite doesn't allow VPN use for several reasons. First, using a VPN to connect can bypass geographical restrictions that are in place for specific servers or game types. Additionally, a VPN might help players hide their location, giving them an unfair advantage over other players.
