Lag every few seconds after the first player joins (or if i join a multiplayer session)

[dandud100]

Describe the bug
So my problem is, that my game runs normaly buttery smooth, but if at least one player is connected to my world the game stutters every few seconds.

It does not matter if the other player hosts the map, if i join it lags on my end. My other players use the exact same mods with weaker hardware and do not face this issue.

My Hardware:
Ryzen 7 5800h
32 GB RAM
RTX 3060 mobile

I only notice the following as a difference in the debug logs... Also i recorded a video: https://www.youtube.com/watch?v=UeZUrSbvdLc

What spams in if no one is connected / after the last player left (game runs smooth):

Update: A member of your discord gave me an hint to this behavior! Thank you Xephos!

So the problem is, that my computer is so much faster, that on x3 I am usually 2 or almost 3 days ahead of my other players and then I need to wait until they catch up. Oh hell this is annoying, but if we play on x1 everything is fine again.

Is there anything that could be done to slow down the fastest computer on the multiplayer session to match the other players. I don't know, maybe the API gives something that allows to slow down the animation speed or whatever.

(Also I think maybe the issue started at the time where our public transport eg busses and so on got bigger)

I also face the same problem, is there any workaround yet?
