For what machine. There are only two services on the freight Layer for the PC, PS5 and Xbox X/S. Not sure if the AI Freight layer will be added. Hentis
They have said they don’t intend enabling any layers on PS4 unless they can do sufficient memory saving to allow it. You are not missing much, there are 2 services.
I don't know if you want layers on PS4. While I would love them, this route needs mega optimization before they are enabled. I am getting unplayable performance without them, I can't even imagine if they were enabled.
