Visual lag for host on listen server
This has been pretty apparent for a while and it doesn't seem to be resolved yet.
For all Unreal 4 games, including the default third person blueprint game for example, the listen server host will see the clients twitching and their movements aren't smooth at all. It's very minimal when you press play in the editor, but once you export and compile the game the listen server host will always experience this visual twitching.
Any clients who connect will see the normal interpolation and the game runs incredibly smooth for them. I've taken the ability to use a listen server at all out of my game and I force everyone to use the dedicated server bat so that they don't experience this, but I suppose it's not really a permanent fix.
Has anyone else noticed this?
I wasn't able to reproduce any sort of lag on the Listen Server using the method you used to connect in a packaged game, neither the one you provided nor any other I tested with. I don't see anything about the system that would cause this, but perhaps the connection isn't very good for the host machine? I might recommend testing this with the host somewhere else and see if that helps. Otherwise, using the netprofiler tool might help discover the source that's slowing down the server.
The reason using a dedicated server resolves this issue is because the dedicated server doesn't have any gameplay events being displayed, so each player is running as a Client and the server is simply running in the background.
