300k
When the population exceeds 300k, the game lags and slows down. I'm 500k in and the game is almost not progressing. Lowering the graphics settings doesn't work. There is no problem with the rtx3060 graphics card. cpu problem 100%. i710700k intel is my processor. Is there anyone else having the same problem?

I get the same issue. I've got a 3060 with an i7-12700.

The game just gets bogged down by too many calculations and whatnot going on. I'm sure they can optimize it a bit with future updates, but I'm not sure how much. When the game released it was the graphics that were causing performance issues, but now the bottleneck is at the CPU, so lowering graphics settings does nothing.

Just a few months ago it was common to see systems like my i5 3060 achieve over a million pop. Now it struggles to get to 500k. WTF?

I regret buying it. I wish I had waited 1 more year.

Edit: I thought the problem was population, but I was wrong. The problem is public transport. I deleted all public transport lines and the game went faster. But of course not at its initial speed. And it continues to use 100% CPU. Apparently I won't be able to use public transportation.

I had the same issue I figured out that it was a lack of parking. When there is not enough parking in an area it overloads the path finding ques and bogs down the your CPU once I stared to salve the parking issue I gain massive improvements to my game performance and then reach a city with 500k

Well the CPU is the bottleneck, but it wouldn't matter if you had a 14900k on LN2 at 7ghz because its more or less the games engine, It will get worse the higher the population. Not much you can do about it unfortunately.

I do like the game up until around that point, I could do the 30fps or even sub 30 is some area's, but once things just get slow regardless of FPS, yeah no thank ya.

So no matter which processor I buy, I won't be able to exceed 500k? Did I get right? Is this a problem with the game? Can they fix it?

I am quite sure you would be able to exceed 500k with a good processor. The question is more at what time the FPS and the simulation, or more visible the motion in the city gets so low or slow you do not like it anymore. I suppose that also depends how well build the city is but mostly on personal preferences.
Can they fix it? Hard question. I am sure, they try hard, because they want to get the game ready for Console. It depends if there are a lot of not really necessary pathfinding calculations going on. As some, like that leading to the homeless bug, are a bug, those will get fixed. And help with simulation speed. Other than that? I do not know. But they said in the videos before release, that how many citizens will be in your city will depend on the power of your PC. I just do not know, why some thought that number must be in the millions, but ...

Even with your current cpu you can pass 500K, wont be smooth sailing if thats what you want unfortunately. Something like a 14900k would help but not in a way that it would matter to where I'd rush out to buy one or build a system around just to play this game, especially since the 14900k's are kinda having issues right now which could be another headache other than this crappy optimized game.

What is the best processor you can recommend for my MSI PRO-H410M-B motherboard? And would that be enough for the game? Yes unfortunately 1200 socket :(

i9-10900K or even an i7-10700K will run fine with this game. Just don't expect the game to be nice to it like most every CPU.

My limit is also around 300k when you start to notice the slowdown. I am convinced it is because they were too ambitious with CIMs. Be creating an unlimited number of different looking CIMS, the CPU and GPU just get crushed. The reason transport systems make it worse is because as you grow more people use transit. Crowds start to form around the stops and street crossings near them. The CPU and GPU go nuts trying to organize and render all those different CIMs and chokes. Then the pathfinding goes haywire as hundreds of CIMs try to get out of the crowd. Look through your city, you will find an intersection overrun with pedestrians near a transport hub. This slows performance.

I took mine to about 340K whereby things began to slow and it became more of an irritation than a hard stop to a stop. My PC had plenty of margin left but my patience was getting tried as the game was more stutter than speed. I had deliberately removed almost all public transport and minimised cars by having no parking lots or street parking. So most of the cims were walking everywhere.

As others have said, many systems can get to a significant population count but, to my mind, it goes against the inference in the original marketing and against my enjoyment of the game (I can buy a can of paint, put some of it on a wall and watch it dry - much cheaper on power and about the same level of enjoyment as a huge city path finding itself away).

I've gone back to a smaller and my enjoyment is rekindled, somewhat.

Will it ever run well with a big population? doubtful, I fear. I don't think there aren't enough players who will buy the DLC's to fund the improvements and that the original ship of CS:2 hype has long since sailed.

FWIW - my system is a 14700K 64G DDR5 4070 Ti and a solid state drive.

I found with the latest update I can get a city to around 560k before it start crapping out noticeably, previously it was 300k. Alot of this is caused by the path-finding algorithm for cims, for instance when they start waiting at train stations in numbers 1k plus you start having issues.

Can we solve the problem if we increase the number of trips in public transportation?
