Much better performance on lesser hardware (linux)

[buhrietoe]

Greetings,
I have an issue with poor performance on my high-end workstation. Its specs are:
i7-4790K, 16GB RAM, GeForce GTX 960 2GB (dual head @ 1920x1080)

I am getting 25FPS on a map, and viewing the Nvidia card information the GPU is virtually unused.

I have a mediocre laptop with specs:
i3-2357, 4GB, Integrated Intel HD Graphics (single head @ 1366x768)

On this laptop in the same map at the same locaton and zoom level I get 52fps.

Both systems run an up-to-date install of Archlinux with the same window manager (i3). Additionally, the laptop is at around 35% cpu usage while the workstation is at 70% cpu usage.

Screenshots of timing info:

Is there any other helpful debug information I can provide?

I was going to ask if you had frame sync enabled but the CPU usage sort of threw that, unless the CPU goes in a tight loop waiting for frame sync.

There are only 104MB of VRAM used when running the game? Is the GPU getting used at all? You could get that kind of performance with a software renderer. Check the logs/terminal output for the "Initialised OpenGL:" line.

Logs would be nice to see here.

Maybe you computer is, for some odd reason, using the CPU's GPU instead of the Nvidia GPU? Would explain why the Nvidia GPU hasn't allocated any memory for factorio textures and it would explain the low fps as the CPU GPU usually is really bad.

[sillyfly]

Don't know how much difference it could have, but one thing to look at is the "Max threads" option on both machines.

This sounds like the opensource driver. Although in that case, I'd expect nvidia-settings not to work either. Nevertheless, can you check which videocard driver is in use?

[buhrietoe]

Doh! It was Mesa interfering. I am indeed using the nvidia driver and not nouveau. I found that mesa-libgl was installed. I replaced that with nvidia-libgl and factorio is performing excellent. No matter what I do I cant dip below 60FPS now. Cpu is only at 4% usage while playing the game and the video memory used is now at 700MB. Thanks everyone!
