Very likely a driver problem. I also do not have such a system, so I can't debug.

bviktor commented 8 years ago

Works fine with HD 530 on Windows 10.

Novum commented 8 years ago

I have a theory why this might fail (I actually require exactly two swapchain buffers). I will eventually rework this.

mrcmunir commented 8 years ago

In Ivy bridge vulkan mesa driver loading fine but has otherrs problem i.e Fullscreen (segment fault) only working with Windows mode and can't change options.

Should be fixed with f52f09eb1f1315c4fa31a522c8d4a110900decd2

The patch doesn't fix the game working with Mesa drivers can you comment if that is fixable or needs driver assistance from Mesa devs? now I get..

That sounds like a driver issue. The Vulkan specs requires implementations to support the InputAttachment OpCapability.

Novum commented 8 years ago

Correct, this is definitely a driver bug.

I have the same error on my laptop with Fedora 25. It has a Intel HD Graphics 520 (Skylake GT2) integrated card. vulkaninfo shows vulkan 1.0.5 is supported.

Btw. its working now on Fedora 26 with Mesa 17.1.3 :-)
