I moved Factorio to my internal SSD, which took a very long time, which made me suspicious. For good measures I killed a back-up program that was (very slowly) running in the background, and rebooted my Mac with the external SSD disconnected. After that the sprites loaded in ±20 seconds ...

Where did you see the "Initial atlas bitmap size is 4096"? In both factorio-current-slow.log and factorio-current-fast.log it is reported as 16384. It was indeed set to 4096 in the two other attempts, because 4096 was explicitly suggested in the topic Solving common graphic issues . Unfortunately ...

In addition to changing max-texture-size= 16384 (max for M2), please make sure to enable gpu-accelerated-compression=true and
gpu-accelerated-mipmap-compression=true. Otherwise, the CPU is performing all the sprite compression instead of the GPU, and that takes a very long time for Space Age!

Hello,

This is a very strange crash… if you can, could you take a moment and update your OS to the latest version of Sequoia 15.7.1, and see if that fixes the issue?

Hello, I'm sorry you're encountering such issues. The latest experimental release 2.0.71 should fix this for you. Enrolling into the experimental beta branch on Steam will update your game to this version.

Forcing OpenGL should have worked too; if you edited your config file manually, please double ...

Scratch that, the issue should be fixed in the next release.

This will hopefully be fixed in the next release. In the mean time, you can force-enable OpenGL by adding force-opengl=true to your config.ini file.

Merged topics and moved to bug reports. Same Intel CPU and GPU model, and similar stack traces (regarding device counters).

Is this attached log from when the game crashed, or from the second run when it loaded just fine? I do not see any indicators in the attached log that it crashed.

Also, can you send me a screenshot of your System Information > Graphics/Displays panel? I would like to see a breakdown of all your system's GPUs and the versions of Metal they do support.

Ok, I was finally able to reproduce the issue on an iMac Pro 2017. I couldn't reproduce on an Apple Silicon machine, which was my oversight. It requires a very specific configuration:

- Non-Apple GPU (maybe, haven't tested an Intel integrated GPU)
- Display with a NON-sRGB color profile (built-in ...

Excellent, this helps a lot, thank you. It's supposed to fall back onto OpenGL in this case automatically, so this is a genuine bug. Thank you for reporting it!

We will never remove the force-opengl hidden config option, so no worries about that! The macos-preferred-graphics-backend setting was ...

Factorio should be compatible with all versions of ...

Interesting, so you can actually get a picture to display, but it crashes around the sprite loading phase. That gives me a place to start. I’m glad that we found a short-term fix.

If you reproduce the crash again, please send us the factorio-current.log, as it likely contains critical information ...

It’s difficult to say if this is the cause, but 2.0.68 switched away from OpenGL to Metal for graphics rendering. There’s a chance that the problem lies in there.

There is a hidden setting to force OpenGL. CTRL + ALT + Click on settings > The rest > force-opengl.

If you are willing to test this ...

[*]Removed Graphics backend user setting.


IMHO, such settings should stay (at least as hidden) for debugging purpouses.


Conversely, I support removing the setting because we have had issues with Windows players reporting poor GPU performance, and it turned out that they enabled the ...

To fix this between game versions of 2.0.60 and 2.0.66, do ONE of the following:
Switch to a different Factorio version
Switch back to the OpenGL backend (Settings > Graphics > Graphics backend: OpenGL) (temporarily 🙏🏻)
Disable vsync
Configure your monitor to use 60 HZ or 120 HZ

Edit: the ...

Ah. I know what’s going on. Thanks for all the reports and logs. This fix will get prioritized. Thanks for testing the Metal backend!

Which type of Mac do you have?

Glad that fixes it!


Will opengl be fixed?


Will we try to fix it? Certainly. However, we’re planning to replace OpenGL with Metal on Macs soon, so this may only accelerate that decision.

Apple deprecated OpenGL several years ago, so the fact that it works at all is about the best we can expect ...
