Crashes to desktop
Apart from 1 rare crash, the game never crashed. Now it it crashes often to desktop.
Is there any faulty graphic option or does mod's let it crash?

I am using only the basics. No despawn, traffic, and line tool

If you got region packs, try removing them and testing again. Some people seem to have issues with them and I can see lot of warnings from them in my log files so it is possible that they conflict with asset pack manager mod or something of that sort. Several assets are too big for the lot, if it is severe enough to cause crash, don't know.

Да, в последнее время очень часто вылетает на рабочий стол, и это не зависит от загруженности процессоров

I used to play Cities on my gamepass account and never had this issue, but I decided to buy it on Steam last week or so to support the devs & pick up some DLC. Since installing it in Steam I've had this very same issue despite it being on the exact same machine as the install from Gamepass.

I, too, came from Game Pass. I wanted to support the devs, but seeing the reviews, and people experiencing these issues, I'm not buying. I'm glad I'm not alone! To those having crashes, I'm so sorry. That is super uncool of the devs to leave players hanging like this.

Have you been getting constant cloud sync warnings in the main menu? I have, no matter what option I choose, and I have had it in the mod workshop too.

I don't use mods (yet) so they were dormant in playsets that I don't use. I unsubbed from all of them fully, leaving only an official playset with the 4 pdx region packs & I haven't had a crash yet.

Nope, there it is.. Pressed [Esc] to take a break and *poof".. game's gone. It seems utterly random.

I've spent nearly two of my vacation days on this and gotten nowhere. I was able to get it working (kinda) for a brief time and then it ♥♥♥♥ the bed again. What is self-evident at this point as that they pushed these region packs and DLCs out the door with minimal QA testing/control and then took yet another vacation. Even when the thing was working, it was throwing errors all over the place. Files were corrupting. These people are a joke. They have no good will left from me.

I'm inclined to agree. I'm pretty pissed off that this was all working on gamepass on my PC with all the region packs but no DLC. I can only assume this is one of the DLC packs that's causing a conflict, but obviously that's what I've just paid for and it's pretty infuriating

Is it just the DLC that is causing crashing issues? If so, can uninstalling the DLC fix that issue? I can rock a game with no DLC as long as it works. I actually enjoyed this on GP, but I'm transitioning off Xbox and back onto Steam. All hail Lord Gaben

i have 4090 and i had no problems either on day 1. and now i have crashes, everything is up-to-date.

I have nVidia GeForce RTX 3060, tried to reinstall the drivers, it stopped crashing after I changed the fps to 55 max. CPU is AMD Ryzen 9 5900X 12-Core Processor, 3701 Mhz, 12 Core(s), 24 Logical Processor(s) - if this infomation can help. I keep an eye on the temperatures. The GPU never goes up to 60 Celsius, so I don't think it is a heating problem.

while reading your post it reminds me.

When the game released i got recommended to change Nvidea settings if you have a high end card such as the RTX4090. becaus my GPU didn't got used fully only 30 or 40%, needed to change in the Nvidea panel a setting that would increase the use of the GPU and take away CPU power.

I didn't have this enabled last time. Not sure the crashing happen becaus i didn't enabled it/or it started happening after a certain update. Maybe it's just random. who knows...

Last night I was finally able to get the game running for several hours before a crash. It was actually playable for a time. For me, the issue was the Japan Region Pack although I think almost nothing is playing well together right now so may be the Japan Pack is fine but it was just the straw that broke the camels back. I basically had to uninstall reinstall the game, use Skyve as my mod manager because each crash was also corrupting files that weren't getting repaired by a Steam verification. (If you decide to go Skyve, make sure you set up automatic back ups first thing, that way you don't have to completely reinstall the game as you're experimenting adding mods and what not). I summary, I recommend:

1. Copy any save games to a back up folder on your desktop
2. Uninstall the game.
3. Reboot
4. Make sure all caches are cleared and (if you're savvy enough) ensure that CS2 is no longer in the Registry using Reg Edit.
5. Go to Paradox Mods website and delete all mods and playsets.
6. Reinstall the game
7. On the paradox mods website, create a new playset, and add Skyve to it.
8. Boot the game, go to the paradox mods page in-game and make the playset you just created your active playset.
9. Exit and reboot the game.
10. Install Skyve following instructions. NOTE: Installing Skyve to the recommended drive location caused me to BSOD. It seems like you must choose the same drive as the game is installed on AND, I've had better luck installing it to the root directory (DriveLetter:\.). Program Files caused a BSOD, every time. Installing on a different drive than the game was on caused a BSOD every time.
11. Once Skyve launches, switch back to CS2 which will be running in the background. Exit the game.
12. Return to Skyve and set up your automatic back ups. Create a manual back up immediately. You'll want to back up all files. I set things up to create a back up every time I quit the game and such as to retain as many back ups as possible.
13. In Skyve, begin adding mods. Checking periodically that you can still A) launch the game and B) get into a map. With each successful test, creating a Skyve back up so that you have a restore point. I RECOMMEND NOT ADDING THE JAPAN PACK NOR ANY OF THE DECAL PACKS. I can't prove anything but I think the Decal packs increased instability overall. Add only what you need to enjoy the game well enough. I have MoveIt, Anarchy, Traffic, Tree Controller, Better Bulldozer and a game map along with all the Region packs except Japan. I think L8n Everywhere (a dependency mod) is throwing a Null error but so far, it doesn't seem to have a serious impact....though the comments section suggests I could try downgrading to a previous version if needed.
14. Finally, once satisfied, start a new game and save it to create the cache directory where save games go.
15. Copy your saves in there.
16. Launch the game, load your save and cross your fingers that it will work.

Note that this is going to take you hours not minutes. Note that if you're stuck on loading screens for long periods of time of no apparent activity once you start adding region packs/mods, this is normal and does not indicate the game is frozen. A 20 minute load time just to get to main menu would not surprise me.

These are the steps that (it would appear) worked for me. I don't understand why this worked and I would never be willing to promise you that it will work for you. If this makes your issues worse, bear in mind that while I'm pretty good working my way around a computer, I have no technical training and will not be able to help you troubleshoot. So pursue this at your own peril. I would suggest, if you're only crashing every couple hours, to suck it up and live with it. Fiddling with it could make your game unplayable as it did mine. What is clear is that this game is a patchwork held together by tape at the moment and is not at all stable. Building on top with DLC/mods/region packs really seems to reveal the poor foundation on which these additions rest.
Ghost code.
Not a terribly accurate term, but we used it for cases like this; when a proggie gets updates and hotfixes and, worse - mods.
When the proggie is this complex... think of it as going psychotic. It's in mental flux. Unstable. And it always will be. It's just a matter of HOW unstable.

Nice, cudos on having the Windows know how and patience to work through these issues - I think you're doing better then many gamers. Just too bad CO can't provide a stable foundation and their development quality assurance is obviously lacking.

Doing regedits are nooo fun...

Getting random crash to desktops as well. No mods. Happened after playing maybe 20 mins. RTX 4090 with up to date drivers, 13900k, 64gb ram. Shouldn't be having CTD.

Edit: city isn't big at all. Maybe 10k people
