Having the minimap enabled causes huge slowdowns making the game near unplayable. The only setting changed in the screenshots below is the "show minimap" checkbox.

Running Arch Linux with i3wm. i7 2600k (overclocked), 16GB system ram, GTX780 with 3GB vram and an SSD drive.
This is not related to the multiple monitor issues some are experiencing. I've tried with only 1 connected and the same result applies.
Just as a side note I play other OpenGL games without issue, such as Insurgency at 150-200 FPS with max settings.

This one is tricky. I have no idea why drawing minimap is especially slow on your computer. The obvious thing is to ask you if you have the latest drivers.

I'm using the same version and I'm seeing no such issue.

Another weird thing is that the initialisation of the game takes 40s, for me it's just 6s (or 12s if crop-cache.dat needs to be regenerated.)

I tried running it with sudo. Turns out the game works perfectly if I do. This is not a good solution though. Why would it require root privileges?

User not in the video group? (Or however that might work on Arch, check permissions for /dev/nvidia*)

Factorio itself doesn't require root privileges. Maybe graphics acceleration isn't available to your user? Or maybe your user is subject to some resource limits.

It used to be that you had to add your user to the video group to gain access to hardware-accelerated graphics. The Arch Wiki says this is no longer needed with systemd, but warns that this is only the case when your logind session isn't broken. So: Are you using systemd? Is your logind session broken?

In either case, if it works under sudo, it sounds like improper configuration of your computer rather than Factorio bug.

As I mentioned previously, I do plenty of gaming without issues, no sudo. I'll do some research and see what I can figure out.

Just to rule out permission problems: strace -e open ./factorio |& grep /dev/nvidia

open("/dev/nvidiactl", O_RDWR) = 9
open("/dev/nvidia0", O_RDWR) = 10
open("/dev/nvidia0", O_RDWR) = 11

Looks all happy. That's as user? At least it's not a permission thing then.

Yep, it is.

Any news about this issue?

Is there anyone else having the same problem?

Found out what the issue was. I had a file in profile.d that set some environment variables.

Using these in combination will ruin the performance for me:
__GL_THREADED_OPTIMIZATIONS=1
__GL_YIELD="USLEEP"

Thanks for the info, we can use it if someone has the same problem in the future.
