Join in Progress Lag Spiking / Server Hitching

Summary

We’re noticing a server wide lag / stutter / hitch (whatever the technical term here should be) when players join in progress. Testing with friends we’ve found that all players in the game experience a sharp lag at the same time that our friend begins to connect to the game from the lobby. From in game, there will be a lag spike, and then a few seconds later the feed prints “{PlayerName} has joined the game!”

FORT-958830 has been ‘Closed’ as a duplicate of an existing known issue. Origin Issue: FORT-958828, Origin Topic: Join in Progress Lag Spiking / Server Hitching

FORT-958828 is now ‘In Progress’! Our team is actively working on it!

I’m also experiencing the exact same issue, and honestly it’s very frustrating. Every time a player joins in progress the whole server hitches badly, which completely breaks the flow of gameplay. This ruins the fun especially in UEFN puzzle/island experiences where smooth performance is super important.

It’s definitely not just a small lag, it feels like the entire server freezes for a moment, which makes the game unplayable at times. Hoping this can get fixed soon because it really kills the enjoyment.
