CPU Usage/Temp seems Odd

[Taffu]

Specs: i7-10750H, 32GB Ram, GTX 2070 Max-Q, Windows 10 Home

I'm having trouble determining what is causing this, but my laptop's CPU temps are off the charts with this game. For reference, I can play Cyberpunk 2077 on Very High settings and rarely pop over 70 C, even at high loads. Ostriv is running my CPU around 30% usage, but my temps pop up to 100 C sporadically on different cores, and my package temp is always high 80's into the 90's. I don't even have a large city...reinstalled recently (I've had the laptop for about 4 months now) and I don't remember Ostriv taxing my old laptop with a GTX 1060 and i7-8750H.

Is this typical? I'm not terribly worried because the CPU's spike and then come right back down to the mid-70's...but I'm shocked at how aggressive the game is on Temp considering the CPU usage is so low. Just wondering. Temps in all other games, including newer graphic & CPU intense games don't display this behavior.

I'm a bit curious about this. May I ask which tool / app you use to monitor the CPU cores, please?

I have an AMD Ryzen CPU, btw, but would still like to see the temps.

I use HWiNFO64 and have a customer desktop Rainmeter display, but you can just view the sensors directly from the application without the Rainmeter.

Thank you.

And by the way, it's quite common to see posts here where people are experiencing the same as you, and I also notice that my PC makes a bit more noise than in most other games when I play this.

I'm not sure what's causing it, though.

Hey. I have relatively old laptop with i7-5500U CPU, Radeon 255 graphics and 8 Gb Ram, but I can't find a configuratio to have a least 20 fps. It works veery slowly. Any ideas? Also to mention, ny PC config is higher than minimum reqs

Honestly, I don't think the developer spent much time writing the minimum and recommended specs for the game when he writes "Graphics: Anything with OpenGL 4.3 support".

I have a laptop:
AMD Ryzen 7 4800H
16 GB Ram
Nvidia GTX 1660 Ti (6 GB video RAM)

I start game at 144 fps, once I hit about 400 population I'm down to about 40-60 fps (not that i'm complaining)

You don't state if 20 fps is at game start with 0 population or an established village with couple hundred population.

Min specs could very well mean, you could get 10 fps and the developer thinks that's okay for minimum specs... it's all rather subjective to each developer

This was in the Alpha 4 Patch Notes:

-Greatly optimized the pathfinding to use all available CPU power

You might consider cleaning out your laptop. Though if the temps are dropping back down it can't be that bad. The temp increase might just be during seasonal changes and everyone is switching jobs which causes a pathfinding spike. That's just a guess though.

The computer is brand new, bought it in late Jan...it's clean as a whistle storage-wise and physically. Like I said, my CPU usage is super low, it's just the temps spike on random cores. For the most part, it hovers around 80-85 C, but then will pop up to 100 C for a second and drop back down. It's odd behavior, given my population is less than 100 citizens. :P

game definitely does nothing to up your temps. I played with stats HUD on for a while, my GPU and CPU never raised past 60 C (PC) and that's pretty much the same I'm getting with any other game. both GPU (passive) and CPU have 30-40 C when operate in desktop mode.

If you have occasional spikes up to 100 C you have to re-check if your cooling systems are properly installed and if it works. Your cooler should keep temps way below 80C even under max load. Otherwise you're in the frying range.

about game performance itself. Yesterday my game refused to start (I blame steam for that) so went ahead and used it without steam (as drm free, just copied my saves and settings over to new folder). I have noticed that game started to run much better without steam and I no longer had performance issues at winter. My village now is almost 600 people and game performs great. try to use drm free version if you have it or cut down all steam features (no overlay, offline mode, small mode so no chat bloat etc). It can improve things if issues we're having caused by steam.

min CPU for 30 FPS is Intel Core Duo E8400/8500. min GPU for 30-60 FPS is Nvidia GT 1030 for small resolution like 1280x (anything from 1st gen of Nvidia cards has support for OpenGL 4.3 and up to 4.6).
8 GB of RAM (game uses 5-6 Gb at max).
post processing off, reflection off, anything you see as CPU dependent - off.

that should be enough to have 30FPS even with big village. If you have high end PC and poor performance that must be reported as anomaly because game is pretty lightweight (at least when it works).

Last year I use to play this on my old Asus G74SX laptop that only had an Nvidia GTX 560M video chip (1920x1080) and could easily get 30 FPS but as expected the frame rate would drop as the population went up. I can't remember exactly but I think I could get up to about 300 population before it wasn't much fun any more due to slower (but still playable) frame rates.

My new laptop gets great FPS with Ostriv, and it's the only game that I can immediately recollect where I get better frame rates further zoomed out, where is where I enjoy playing the game to have a better overview, I'm guessing some things don't render the further you zoom out, I'm pretty sure that I'm seeing the LOD of trees really change as I zoom out which is great so that we can get nice frame rates zoomed out too.

could be. if tiny objects don't render and don't take resources that would be proper optimization.

I have kind of the same temps spikes after building a new house. My Ryzen 5 5600X gets a load around 30%, and looking at per core load that seem to be about 3 of the physical cores fully loaded for a few minutes.

The i7-10750H is the same 6 core 12 thread CPU so it fits.

Because I have a big cabinet I have better cooling than a laptop, using a Noctua NH-D15 it will spike to around 70C and fans going pretty fast.
This seem to be normal as a 3 core load still keep the CPU boost frequency at the max of about 4.6Ghz, any more load and it drops by 100Mhz per additional core, and temps go down.

The issue is the massive heat output on a very small area that is not able to transfer to the heatsink fast enough.

With CPU tests that put unrealistic load on the CPU I have managed to peak at 85C on a 3 core load. That is still below the 95C limit when CPU will throttle.

[Gazer75]

This latest patch have made it even worse...
Any building that completes will hammer the CPU and it went up to 80C with fans going near full blast. It takes ages for this to stop so I'm essentially stuck with a CPU running near 80C with about 30% total load.
Save, exit and restart fixes this insanity.
