I personally wish Turn 10 would disclose some of the technical detail on how the network configuration is set up. Seem like it would help the community better configure private lobbies to help ensure a more enjoyable experience for all participants.
I was one of the cars that were invisible to other players on the track (even though I could see everyone else).
I have double checked my NAT type (set to open) and I am hardwired on look 1GB connection. Not sure what other settings I can control. Others in the group that was also invisible reset consoles, routers, and modems. It didn’t seem to help much. I hope that this is a game issue that can be addressed.
It goes without saying how disappointing multiplayer in FM7 is compared to FM6. Maybe this is necessary growing pains as Turn10 grows their PC chops (I am all for them extending their player base).
