Factorio Forums

To whom it may concern:

I started playing Factorio on steam for several months game play has been fine. Over the last few months the process of saving and loading has taken excessive amounts of time.
Loading from main menu games takes 1min 10 sec
during game hitting save takes 1min 30 sec
Hitting escape to return to main menu then hitting quit takes 50 sec

720 MB save, with a 1.7 GB actual map inside, that sounds excessive. How far have you explored and polluted ?

Can you please upload your save file somewhere? (google drive/one-drive/dropbox)? As Koub said, the save is super large. The reason it takes so long to load/save is you're running out of RAM. But, why it got that large is another question that I can only answer if you upload it and post a link.

First I apologize I was working on my original post and trying to follow all of the recommendations on various pages I hit enter by accident and started a partially completed post.

Thank you for the reply with not all of the information.

How far have you explored and polluted ?
I have visited most of the planets on the original system and built bases on 5 or 6 of them. It sounds like part of my problem is I let the satellite scan the entire surface of many of the planets, that would explain the map size. I suspect there is no way to "undo" that?

I have uploaded the save file I call "Space" to google drive.

Let me know what else I can do to assist in troubleshooting.

The link to the save file is listed as private so I can't download it.

I changed the access rights to the file, you should be able to download it now.

There is a mod that hides unused chunks.
So, yes, its possible.
Sorry, I dont remember the name, but someone might remember now that I brought it up

Sounds like you're playing Space Exploration. There's buttons in the Universe Explorer where you can delete unused planets/orbits, or trim it to only the parts you built on (trim is basically the undo of the scan). If you do that for all zones then it should help a lot.

I followed the recommendation from Stringweasel and deleted over 50,000 chunks!

She was chunky!

:: UPDATE ::
I saved, closed, completed restarted PC. Starting game and I do not see a noticeable difference. Do I need to do something additional? Maybe there is another piece of the puzzle.

Yes, sorry. The replies from other people cover what I would have said. I tested locally and went over each listed location and trimmed them and it reduced memory usage from 12 GB to 5 GB and reduced the save size from 700 MB to 250 MB.

Can you help me understand better what you did in more detail. I went into the each Universal Explorer I clicked the scissors icon, then hit the trash can icon. I was able to delete over 50,000 chunks in total. But was not able to get the file to reduce in the amount you were. Also where would I find the memory usage so I can track this in the future.

Thank you
