Async auto save in multiplayer but not in singleplayer?? Why??

I'm really trying to understand here why the more complicated multiplayer system has asynchronous saving of the game state but in single player we have to wait for the auto save.
Can a dev explain why we can't turn on async autosave in single player?

Non-blocking save only works on Linux and OSX, as posila wrote here:

Does the server run Linux, do you run Windows on your machine?

Not running a server. Single player I don't want to have to wait for saving. Reading through some of the questions / answers in that thread is appears for some reason they can't do non blocking saves in windows but they can on Mac / Linux. No real reason given, just that it can't be done.
Really curious what OS feature is lacking that keeps this from working?

Windows doesn't have the
fork system call, which async saving is based on.

That does not explain why the OP claims to have non-blocking save in multiplayer without any Linux/MacOS system involved. How does that work?

I don't see them claiming that. I think you misread.

Ah, but if you VM a linux machine to host a server, then you can get the fork command in windows for the async save.

Thanks for the info, appreciated.

A workaround is turning off compression in config.ini - this speeded my autosaves up noticeably...
Code: Select all
; Options: none, fast, maximum
; autosave-compression-level=none
