solutions to multiplayer open world lag?

[DrwHem]

my open world that i play with 1 friend has gotten excessively laggy every time he joins me. no fun to play an open world survival game alone so im not sure what to do.

1) Without specifying the technical characteristics of your PC, it is impossible to say anything meaningful. It may not be capable of running as a server on its own.
2) Minimum 32GB of physical Ram, also before running Icarus you should unload all unnecessary programs to free up as much Ram as possible.
3) DX11 only, FullScreen only. Disable 'Light Shadows', reduce Shadows setting to Low.

I have DX 12 and 64 Gigs of RAM and 8 gigs of Vram with an M2 drive.

Run your server instance off a separate machine. Running on your own + game it will lag. I did this on a 5800x , 32gb 4ghx ram, and a gen4 nvme.
Put the server on old laptop ( i7500u) and went from 30fps to 50..
Since then built a dedicated machine, and most time get 70+, cept around our huge base

The lag is also present on dedicated servers. It's not your PC, the game is not optimized as it should be. Especially around bases.

I agree, the game is very poorly optimized for multiplayer, its OK for the fist 15-20 hrs after that it gets unplayable after the fist friend joins, I am running 130 fps on my Samsung Q9 ultra wide monitor everything maxed out, after the first friend joins it goes down to 90 fps, after the second friend joins it goes down to 30-40 fps in the open world, when going to the base it starts to rubber band and frames drop to 16 fps.

on some points inside one of my friends bases, there what seems to be an invisible line inside his base, we can go back and forth over that line and it seems to get stuck at the same place every time.

Setup a dedicated server even if it runs on the same PC you play. It will offload the multi-player processing to a different process thread freeing up the game thread.

This would be alleviated some with the dedicated server obviously. Almost all of the stuttering is CPU constrained. Meaning the CPU has too much to process at once so it can't send the frames to the GPU fast enough for the GPU to draw - having a faster GPU won't fix this.

You've said it yourself - The first 15-20 hours are fine. I'd go out on a limb and say the game was actually optimized for mission play where you don't spend more than 5-10 hours on a map to complete your objectives.

It's the new Open World mode that struggles with people playing on it for extended hours. The way the game saves and processes every bush, rock, and stick you've pulled up seems to bog it down considerably once you reach a certain point.

If you're really struggling to enjoy the game because of the late game open world stuttering but want to keep playing give the missions a shot for a while until the Open World fixes are in. And give the Outpost mode a shot for tooling around between missions - its resource respawn mechanic and smaller map mean you can build much larger/elaborate bases and play for longer hours without the stuttering late game Open World currently suffers from.

The Devs are actively working on new fixes for the Open World issues.

Hey,

We already tested the dedicated in various scenarios, from VM's to fully dedicated racks, assigning CPU's (Priority and such) and also memory to see where the problem lies... the best one of all of them was just to run the server on the my local machine and then join that, this gave everyone the equal pleasure, and I didn't loose fps, the only issue after this is the invisible line (Haven't read that post yet :D) this causes lack of game pleasure for one of my friends to the point where we are just gonna stop playing the game until it's fixed.

It's a shame because "actually" the game is very nice and has so much potential!

Anyway Satisfactory will be on V 1.0 soon, so there will be no time for it :P

Don't bother troubleshooting this. This is a known issue, performance is in shambles but they have stated they are adding some optimization in the next update.

Wait it out.

Not trouble shooting, just placing more info on the net so that others can use it :D

I would say that if you only have 1 other friend that (If you are not already running a dedicated server then...) go to this link: https://survivalgamingclub.com/icarus-dedicated-server/ follow the instructions step for step, if you have any difficulties in setting it up then I can help make it a little more obvious.

Running it dedicated on your PC will make it so that you do not loose your frame rate, for each person that joins, you loose on average 40-60 fps at this moment.
