Ubuntu Linux vs Windows

[jelle82]

I am not sure of I need help, as more to confirm an observation.

I installed Factorio on a Windows 10 Laptop and on a Ubuntu 16.04 Desktop. Both have an i5 Intel CPU, that are fairly similar - according to cpubenchmark.com, the CPU of the laptop is slightly 'worse'. The laptop has an SSD.

Now: on the Ubuntu Desktop the game drags when I go to my 16 furnaces. The game becomes almost unplayable when I go to that area of the factory. On the Windows laptop I opened the same saved game and this does not happen. The game keeps running smoothly.

So my question is, I guess: Does the game perform worse on Ubuntu-machine than on Windows in general? Or do I need to dig deeper to look for a reason in performance difference?

Are you actually using your GPU to render the game and not a software renderer? Check the "Initialised OpenGL" line in the log. The game is certainly supposed to be playable on Linux.

On comparable hardware the Windows and Linux versions should perform the same, as long as the drivers are installed correctly as prg mentioned. If you only get this near furnaces (or boilers/steam engines) then smoke might be the reason, some graphics cards struggle with it. You can disable smoke (and clouds) in the graphics options, that might help somewhat.

As prg already said performance is depending on more than just the CPU, if you post your log and debug-setting screenshot (see performance issues in FAQ) we could tell you if it is expected what you experience.

Okay, so this is in the log from my last play. It looks like OpenGL is being initalised. I added the debug-settings screenshot.

You have 20/60 FPS/UPS, so you are definitely limited by your graphics card, which is not surprising since the GT 430 performs even worse than most intel onboard chips.

[prg]

Check nvidia-settings for GPU/PCIe Bandwidth Utilization.

What GPU is in the other system that is working better?

The other GPU is indeed an Intel Onboard Chip.

Check nvidia-settings for GPU/PCIe Bandwidth Utilization.

Is this what you mean?

Is this what you mean?

No, it's under GPU, not PowerMizer.
