Post all bugs you find here

Game crashes on startup on my machine. Managed to snag the following screenshot from the console.

Thank you for reporting the startup crash. I’m on it.

It seems the issue is due to missing Vulkan drivers. Could you update my graphics and Vulkan drivers, please?

Verify Vulkan on Windows

1) (Optional) Install Vulkan SDK

  • Go to vulkan.lunarg.com and install the Windows SDK.

  • This adds tools like vulkaninfo. (Many systems already have the Vulkan runtime via GPU drivers.)

2) Run vulkaninfo

  • Open Start → Windows PowerShell (or Command Prompt).

  • Run:

vulkaninfo 

If not found: run it via the SDK path (adjust version as installed):

"C:\VulkanSDK\1.3.x\Bin\vulkaninfo.exe" 

3) Interpret the output

  • Working: You see GPU name(s) and a line like Vulkan Instance Version: 1.3.x.

  • Not working: Errors (e.g., No Vulkan devices found) or tool missing.

4) Fix common issues

  • Update GPU drivers (then reboot):

    • NVIDIA → GeForce Experience / NVIDIA driver installer

    • AMD → Adrenalin Software

    • Intel → Driver & Support Assistant

  • PATH not set? Either re-run the installer or call the full path to vulkaninfo (see step 2).

  • Laptop with iGPU + dGPU: In NVIDIA/AMD control panel, force apps to use the discrete GPU.

  • Still failing: Reinstall the Vulkan SDK (Windows), then try vulkaninfo again.

Apologies for slow response. Graphic driver update + Vulkan SDK install seemed to have little effect, but I did find a solution. Adding "DISABLE_LAYER_AMD_SWITCHABLE_GRAPHICS_1" with a value of "1" to the system environment variables and restarting allows the game to run (though the vulkaninfo command still doesn't work, likely a separate issue.).

No problem glad it’s working now. I forced the Windows build to use Vulkan by default, so it should run whenever Vulkan drivers are installed. It looks like an engine issue, but I’m hoping the next Bevy update addresses it more comprehensively.
