[PC] Multiplayer lag despite decent connection

Troubleshooting Hub Legacy Troubleshooting FH4 Troubleshooting

I seem to be lagging like hell on multiplayer.

It is the same every other lobby.
On my screen everything is fine, but for the others, my car is flying around lagging.
They even have shown me some clips and it’s really hardcore lag.
It’s not funny when tandem drifting is your only reason to play this 100€ game.
In FH3 and FM7, everything is just fine.

My PC is only using like 60% of its potential to run FH4 on full settings,
so hardware is not the issue.

My internet connection is always around following stats:

PING: 11ms
DL: 20-30 Mbps
UL: 10 Mbps

So internet connection can’t be the issue.

I was looking for some help, maybe on opening ports or anything else, I don’t know about this kind of fix procedures.

EDIT:
Looked up a few things now.

  • IPv6 teredo status = default
  • NAT type = open
  • Xbox App shows a 30ms ping

I have similar issues on my pc. I found that my lag is caused by the game uploading/synchronising my save file.
My game save is around 80MB and is automatically uploaded on a regular interval at unlimited speed - causing severe lag as it hogs all the bandwidth.

It is also uploaded between rounds when playing an online championship.

I have opened a ticket but just got a generic reply back

I just wish the game put a limit on the upload speed for the game save :frowning:
