As of my knowledge to date, mover is using standard unreal replication. I’m not entirely sure if turning on iris would have any effect. Would have to run some bandwidth tests. It doesn’t seem like epic is focusing on the netcode side of mover as much as the scalability side. I’m guessing their focus is to get all of the basic features up and running then optimize. Things are looking up since that CDPR demo was showcased. Hopefully we will see a lot more support for mover.
