I think this has been happening for a while… but for whatever reason some of the networking packet simulation settings don’t seem to work anymore. My project currently has these in DefaultEngine.ini:
[PacketSimulationSettings]
PktLag=2500
PktLagVariance=500
PktLoss=50
PktOrder=1
PktDup=1
Now, I’m definitely getting packet loss - but Lag and Variance make no difference whatsoever. This was working fine a few engine versions ago. Either that, or my netcode is **** good.
