Running out of memory with minimal assets and mods

[Robo_Warrior]

Hey folks!

I was wondering if running out of RAM (16Gb) with less than 200 assets is normal? I have 192 assets loaded and 6 (mostly interface) mods. I went though all my assets and cleaned old broken ones away as well as all the heaviest ones. Yet I still can't manage to survive past the loading screen.

Even with 0 workshop assets my game will randomly crash after starting a new city because of running out of memory. If there's a memory leak how and where can I fix it?

After a 2 year hiatus I recently bought all the worthwhile DLC, (50€ worth) So it would be nice if I could actually play the game... So any help would be greatly appreciated!

deff not normal i have 1800 assets and use close to 16gb! what i would do is do a complete uninstall and reinstall of the game.

Yeah I figured I've seen some crazy 3000 asset players with 16Gb of RAM while I struggle to launch with a tenth of that!

I also did that as the 1st thing before I started playing again. Also unsubscribed all of the workshop content and went in to re-download all the good stuff. (Took hours)
I did both of these things to avoid such problems yet this is what I face.

Going to verify game cache because apparently missing vanilla files can lead to a vanilla memory leak, which explains crashing post loading screen. Yet that doesn't tackle the whole running out of memory whilst having less than 200 assets loaded debacle.
And I need those assets...

(Already using the Load Screen Mod. It gets to around 13 Gb during loading which of course hits the magical ceiling with Windows taking the rest. Meaning the whole game goes down along with all the other running software.)

you can also use this to see if your assets are too high poly

if you have any that are red especially vehicles i would consider removing them. you don't want too many super high poly vehicles running in your city this will eat up memory. it's ok to use assets that have a high poly count just not the ones that will spawn hundreds of them :P

Okay I'll give this a go with the assets and see which ones do what. Though I don't know how much that will matter because I just checked that my Cities:Skylines is using just around 10 Gb of RAM just to run the vanilla.
Something isn't right here...

Try rebooting your computer to clear out memory.

Launch Steam only,

Go to Library

Scroll to cities skylines and right click it and select Properties.

Click Set Launch Options, then type in exactly --noWorkshop click okay

Close properties windows.

Click on Play button for cities skylines start a new city then report your results here.

are you using any custom maps? some maps use a lot of memory on their own especially if they are full of trees.

Just did this and it definitely "fixed" the issue of the game using up too much memory in vanilla. How come assets affect performance even when disabled? My game is running at roughly 6 Gb RAM usage now, when it was 10 before.
This is very interesting. I'm just not sure where to proceed from now.

This is what I thought as well so I started trying vanilla maps but the results were similar. Though could the performance heavy maps somehow have an effect even when disabled?
(Turning off Workshop test indicates that could be possible...)

if the game is running fine with no workshop content than it's definitely got to be an asset that's eating up the memory. you'll just have to track it/them down. you can use that mesh info mod to do that. try enabling a few assets at a time and using it you can start seeing which assets are stealing memory.

I updated from 16 to 32 G today, while it costs money I saw improvements. Glad I decided to spend the money.

Do the same test, but only use --disableMods instead, then report your results.

I have 64 Gb and my typically loading in the city it climbs to 40-45Gb of usage. It levels off around 30-35Gb during most gameplay. Memory and processing power are critical for C:S. GPU is secondary.

Yes it definitely was an asset or two. I heavy handedly got rid of many assets and when I got the game going enough for it to start I went further and got rid of the heaviest assets using the mesh info mod.
Now I run at a comfortable 10 Gb usage of RAM while running 167 assets and 12 mods. I'll be more careful with adding assets & mods and maps in the future.

Also thank you everyone for helping out. I missed this community for a reason!
