Loading screen stuck loading

[76561199165565988]

Hey, i have been playing with a city for pretty long time without any problems, but when i tried to load now the game stops loading after 75-90%. The chirper keeps spinning and the time goes, but the city never loads. What could be the problem? I have 6400+ assets and 135 mods, of which 105 are enabled. The last time i played, i had 6420 assets or something, and it worked. Then i subscribed to many new assets so i had over 6500 and now i unsubscribed assets to 6403, and it still doesn't load. Ram is 16gb, so what's the problem?

Sounds like a memory issue. Did the numbers in the middle of the Loading Screen turn into the red?

Cities Skylines needs about 4GB of RAM. But that is just for the base game. When DLC's and assets from the Workshop are added, the amount of RAM needed goes up. A lot!
Here's an indication of the amount of RAM used by the game when DLC's and assets are added:
8GB RAM: 100 assets, 1-2 DLCs
16GB RAM: 500 assets, 5-10 DLCs
32GB RAM: 2000 assets, 15 DLCs
64GB RAM: 4000 assets, All DLCs

If you do not have enough RAM memory, you can set up a so called 'Page File'. This is an allocated amount of memory on your (much slower compared than RAM) harddrive. Here's a guide made by snowflitzer on how to do this: https://steamcommunity.com/sharedfiles/filedetails/?id=2114415052&searchtext=page+file
Best thing to do is to upgrade your RAM memory. If your computer can't handle more RAM, then unsubscribe from any asset you're not sure of useing. Only subscribe to assets you're really going to use.

No, the screen did not turn red. I have set my page file to 85GB. And as said, it worked until yesterday with more than 6420 assets. The city runned smoothly, but after subscribing to over 6500, then it stucked loading but after that i unsubscribed to 6400 but it still is stuck on loading screen. I look at the timer. After 1 hour is passed, it still loads without the progress bar progressing. I can't buy new ram right now because it's expansive.

Understandable. Well with 135 mods (disabled mods can still influence the game) it wouldn't hurt to check if these are all ok. Here's my next copy/paste that might help:

You can check this list to see if you're useing any broken/outdated or incompatible mods (the list has several tabs at the bottom): https://docs.google.com/spreadsheets/d/1mVFkj_7ij4FLzKs2QJaONNmb9Z-SRqUeG6xFGqEX1ew/edit#gid=0

Or these collections (nice thing about these, is that you can easily see if you're subscribed to any broken/outdated or problematic mods/assets. Make sure you're NOT subscribed to any of the mods AND assets in these collections:
https://steamcommunity.com/sharedfiles/filedetails/?id=2056891584

Well, i have had all those and the game has worked all the time, so i don't think it's because of those mods. I think it's because of some of the assets, but i must be careful unsubscribing so i don't corrupt my city.

Check the collections, they're for broken assets as well. Maybe you've subscribed to a broken one recently.

I can check but i haven't subscribed to new collections recently.

I'm curious if you upgraded to Windows 11? I'm having the same issue, except with the Loading Screen Mod, it actually tells me it failed to load. I never had any issues prior that I couldn't resolve.

Sounds like maybe a simulation error. I recommend adding these two mods:

https://steamcommunity.com/sharedfiles/filedetails/?id=529129546
https://steamcommunity.com/sharedfiles/filedetails/?id=1620588636

Then before loading your save, go into Options and find the Loading Screen Mod. Find the Safe Mode options and enable them. Then try loading your save.

If that does the trick, save as a new file and remove the above mods again.

If it doesn't work, we'll need to look at your output_log.txt, which you can't attach here. In that case I recommend posting on our official support forum:

1. Disable the DLCs you don't need. Go to Manage My DLCs on the CS Steam page. Those things all get loaded up into memory. Only use what you need.

2. I start new cities with a blank slate, so to speak. Basic MODS, basic assets. As the city progresses, I add stuff as needed. After all, why subscribe to 10 GB worth of a certain railroad track when you won't need it until much later? Unless you've got RAM to burn.

3. I know know this: save your city in progressive stages--Rock City 01, Rock City 02, etc.

Here is a picture of what happens: https://no.pinterest.com/pin/816136763730224464/

I tried with another savegame, and the same thing happens.

I wasn't talking about the entire screen, I was talking about the memory numbers in the middle of the screen while loading. Looking at the picture you posted, they're definitely red.

Having a pagefile is good. But having the game depend heavily on it, isn't. The numbers show you need about 64GB's of RAM. While you got 16GB's.

I still think reducing the amount of assets you're subscribed to is the best solution.

But then tell me how it has worked until recently.

RAM memory is also called physical memory. It's really fast in exchanging information with your CPU. When you do not have enough RAM, the game uses a pagefile (called virtual memory). This is an allocated amount of memory on your much slower harddrive (even SSD's are considerably slower than RAM).

While you play the game, information is continuously exchanged between CPU and memory. When a big amount of that info is located on your much slower harddrive/pagefile, the game becomes less stable. This doesn't mean the game crashes immediately (it can even go right for a long while), but when something extra happens (like an autosave, or your antivirus starts scanning), it can become too much, and the game crashes. (usually straight back to the desktop)

My understanding is limited and based on the vid below, and I'm not 100% certain this is what's causing your game to not load. But I had 16GB's of RAM untill recently, and after upgrading it, my game has become a lot more stable!!

It worked perfectly. It saved smoothly and everything. And the chirper is spinning and the time is going but the city never loads and the progress bar never progress. It has never happened before.
