Anyone else worried about the performance?

[Grgich]

I hope it ain't just me, but Cities Skylines with mods has a really poor performance on my computer, so I'm kinda worried about Cities Skylines 2. With all the new simulation features they announced, I really hope they found a way to improve the overall performance of the game...

Performance comes down to size of city and how your computer can handle it.
You need plenty of RAM, a decent CPU and an even better GPU :)
If your computer struggles, use less assets, less mods who eat performance and tune your computer. There is a lot you can do which does not cost money but there is a limit to it as well.

Ram speed does very little for games in general past a pretty low bar, but yes cities 1 is cpu bounded 100%, even without a top of the line gpu. Here's hoping cities 2 actually allows for actual city sized populations without crawling to sub 10fps.

It doesn’t need an amazing GPU. The game is CPU heavy and bottlenecked. The fastest clock speeds for CPU and RAM are what’s needed. Of course, all other components have an effect and a good GPU will certainly help. I’m speaking of CS1 obviously.

Nobody knows (or is allowed to say) how CS2 is performing yet, but I share Grgich’s concerns. The minimum specs look very modest. It does look like assets and textures will take a big jump in quality judging by the recommended VRAM amount, which is a good thing in my view. Texture and model detail can always be turned down, but it can’t be turned up from what is supplied. This is a game they are probably planing to have a similar lifespan as CS1.

Cool. Good advice!

Agreed.

Yes I am, I have 4090 with 13th gen i9 when I played CS1 last time a few months ago, Sure better FTP but still stutters at times - slowly drops FPS when the city grows and if it you have many trees (regardless if you stayed within the official numbers), Rendering does not very good regardless of what LOD you set or what LUIT you use, on my 4090 and i9 13 gen with 64GB of DDR5 RAM running at 6000Mz I still had to slow the speed of the game down so the processing slows down to give me more FPS.

Massively better when I was running it on my 2070 Super with i9 9th gen but All this just sucked

I can blame my Mods, I had over 100 mods and over 2000 assets but without all that, it was just not enough fun.

Fingers crossed: Hopefully, They have fixed performance issues. I feel like they actually have as in Gameplay videos, the game can render FAR so some LODs might be set higher like building, etc - I Still see popping with trees though, when you get closer it loads high-def trees and it is very visible just like it was in CS1

Yes I am really worried about performance. The CS1 single-core limitation was a deal-breaker for me. Strangely, for CS2 they did not proudly advertise how much more they can simulate by proper multi-threading. They just mentioned that the maps are bigger but that's not the same.

It's dead quiet about this topic and if they really did the proper multi-threading implementation, I would expect them to brag about it as one of the first things. If done properly, it should be easily possible to simulate way more than 1mio people in a city on higher-end PCs with good performance. But they refuse to comment even when asked directly several times.

Even worse, in all their demos so far, the largest population shown so far was a mere 90k. You would assume they would have sneaked in a short clip where you would see e.g. a population of 478'239 or so to get people excited and start speculating. Speculating in the positive sense of what's possible, not speculating in a concerned way that we have to do now.

So yes, I do not have a good feeling about this and it would be again a complete deal-breaker for me. Let's hope they are just playing some evil mindgames with us and will reveal a positive surprise in the next Dev Diary (on twitter they said they would address some performance topics in the dev diary of 26 Jun). It would be a pity if they dared to release another city simulation game limited by single-core performance in 2023, because feature-wise it seems they did an awesome job with CS2, in my opinion.

I have a RTX 2070S, i99700, 32GB RAM, I get 20fps in CS1. Yes Im worried about the FPS in CS2.

@Geist, I am afraid on this one you are not correct. You can very well parallelize city simulations. Check out Highrise City that can make use of all your CPU cores and manages beyond 10 million citizens. But as a developer you need to understand how to do it and you must be willing to take the development effort.

[Trouter]

The developers have said that the performance will be higher due to the "full utilization of multicore CPUs", so this seems to confirm the game will make better use of modern CPUs.

[sirupflex]

Yes it seems that for CS2 they indeed implemented full multi-threading that can make use of all the CPU cores. Although I'd be happy to get a more clear confirmation on this part from Paradox / CO, because so far they only issued these general statements that they keep repeating, even when asking back.

I've seen too many development studios announcing "multi-threading support" or similar for their simulation games and then it turned out that they can only load 2 CPU cores, and similar stuff (like TPF2). So I hope CO really understands "full utilization of multicore CPUs" in the same way I do, i.e. if you have 8 or 16 CPU cores, CS2 will use all 8 or 16 and performance will scale accordingly.

Nice, very nice.

That is fantastic

Is there any article or reference?

From the paradox website:

"This means pathfinding calculations are more numerous and more in-depth than in Cities: Skylines as the agents have more features affecting their decisions. However, the calculations are more efficient, resulting in higher performance across the board as the pathfinding and simulation among other calculations take advantage of all the available processing power of the multicore CPUs."

And what is even MUCH MORE IMPORTANT is this:

"Also, as a major improvement to the first game in the series, Cities: Skylines II doesn’t feature hard limits for agents moving about in the city. Overall, the performance of the simulation and pathfinding is vastly improved which means larger populations are possible. The only real limits to the simulation are the hardware limitations on the platform running the game."

<<<--- No Agent limit!!!!

Sweet, thanks for sharing

in 2023 this should be a standard for all games. multi thread is the way to go to have improved performance

[sirupflex]

CO confirmed on Twitter that CS2 can really use all CPU cores you have.

This was the question:
"Does it mean CS2 is fully multi-threaded and makes use of all 8+ CPU cores? I.e. it only starts to lag / stutter once all CPU cores reach their limits? (assuming GPU or general I/O is not a limit before, of course). Please confirm."

Answer CO:
"Yes, it will take advantage of all your system has to offer"

That will be the biggest factor in a performance uplift here.
I will pass if they did not upgrade the engine.
I'll wait 5 years and get the whole game plus 500dlc for 70 dollars
