I have updated the game. When I ran it, it said my graphics card does not support opengl3.1. I rebooted the system and got a new error: "Unable to query size of supported swapchain formats."

Hello @CandyFiend, it looks like you have an Optimus laptop. These laptops usually use the Intel chipset to render, but this section of your system information tells us that Vulkan is broken on your system.

There's a couple options you can try. These are separate suggestions.

1. Try setting's the game's launch options to -gl which should tell the game to use OpenGL.

2. Install the vulkan-intel system package which should let the game render on the Intel Haswell chipset.

3. Look into using nVidia's PRIME Render Offload. Setting the game's launch options to __NV_PRIME_RENDER_OFFLOAD=1 %command% might be all that's needed to use that.

Thanks, I will try this. Yesterday, before the update, the game worked for me.

I recently turned off intel graphics.

Now I found that the system deleted the nvidia config in /etc/X11/xorg.conf.d/ and replaced it with the clear mhwd config. Of course, he did not copy the settings and the system again began to use Intel graphics without using nvidia GPU. I copied the old settings to a new file, rebooted and it worked again.

Glad to hear you got it working. Closing because this was a system config issue.
