Factorio Forums

Hi

i had this exact same problem already once with an older version of the game

see here: viewtopic.php?t=119541

It got fixed in 2.0.14

Now i upgraded my system because i had overall performance problems, because of weak hardware.

I can see the behaviour in the menu screen with the background action. Also immediately visible after starting a new game with just standing around.

I did not include a save file, as only starting a new game without doing anything is showing this behaviour already.

I am not using any mods, no space age, no elevated rails, no quality, nothing, just pure factorio 2.0.42

System specs:

AMD Ryzen 7 7800X3D
DDR 5 32 GB 6000mhz
RTX 3080

Tried on a SSD and on an NVMe M2

Here are two screenshots right after the freeze happened here is one where i have normal performance in between

Something happening in the render "pre-prepare" stage. I don't think I've seen that before.

A lot of stuff seems off, the update rate is low while the update time is consistently less than 1ms. No idea how to make sense of those values, I'd check temperatures.

The Temps are fine, cpu around 65-75°C, gpu around 50-60°C, i have no problems in any other game. So i doubt it is a direct problem with my system (hardware wise)

Well, it shows low UPS while update times are minimal which does not make any sense unless you changed the game speed. It show low FPS while the graphics card is sleeping more than 50% of the time which does not make sense, on top of that a very high pre-prepare time which is unprecedented. And all of this while running a brand new save without mods on very common capable hardware and windows.

Try if the issue persists on a default .zip install.

Also run some common benchmarks or other games, to verify if your hardware results matches expected performance.

I think it's just skewed by one or a couple really slow frames

Ryzen 7 7800X3D with RTX 3080 shouldn't have any slow frames. I have much slower CPU Ryzen 5800X and my FPS UPS is always 60/60. OP needs to investigate his Factorio and Windows installations and verify hardware performance so find out what is wrong.

I am just looking at UPS and update times here, rendering has no bearing on them. The slowest update of the last 10s in the first two screenshots is below 1ms, so just counting those worst case updates this could easily run 1000/s and yet fails to do 60.

Well yes, we agree that something is wrong.

Hmm, I know that render is asynchronous to update but is all of the render preparation stuff? I thought not but I'm second-guessing myself now. If it has to wait for those render preparation steps to start the next update that would explain the UPS discrepancy.

It is done on the cpu but from my understanding fully parallel to the next update, so it impacts FPS but not UPS.

Thanks for the replies so far.

I am able to play others games without freezes.

- played RoR2 without interruptions.
- ran 3dmark timespy extreme without stutters or freezes
- ran dyson sphere program on a late game save without freezes, only lower fps and ups, but had that before as well

So i am pretty certain that it is not faulty hardware at this point, i am running the 3dmark stress test right now and will run the memtest afterwards. But i doubt it will show faulty hardware or problems.

I will also try to run factorio from a fresh zip download and see how it compares to the steam version of it.


3DMark Steel Nomad Stress Test Fresh downloaded ZIP factorio on the NVMe
Fresh downloaded ZIP factorio on the SSD Ran the Memtest64+ And it did pass

Just updated to 2.0.43 and still having the problems

This seems to be a Hardware problem which is still to be found, as i just found ONE other game that shows the same symptoms `Nomad Idle` therefore i think now as well that it might be a hardware problem.

Thanks everyone.

Could be also your software, like antivirus etc. You could try fresh install of Windows, or Linux install to verify if it happens there. Also, small first step could be creating new Windows user and seeing how it works there.

Another thought: One of the screenshots shows that you have two GPUs there, one built-in CPU and another dedicated Nvidia card. Check out which one is powering Factorio while running. Log is showing Nvidia, but maybe double check in Task Manager.
