2013 Intel iGPUs pretending to have Vulkan support are actually one of the worst targets (on par with bad mobile phone drivers), because the hardware doesn't fully support vulkan, the implementation is buggy and incomplete (and Linux only, though to be fair buggy and incomplete applies to all intel gpu drivers, at least for dx12+vulkan), and it doesn't pass CTS (any sane vulkan app will block running on non-conformant drivers because they're a nightmare).
Fake news: Intel Graphics on Linux submits its drivers for Conformance Testing and gets the official stamp by Khronos for its products: https://www.khronos.org/conformance/adopters/conformant-prod... . The drivers are good and often conformant on launch. I'd argue that Linux is better than the Other OSes if you want Intel Graphics.
...did you even bother to search through that? There aren't any Haswell iGPUs in there, because they're non conformant.
I'd agree that overall Intel's Linux drivers work better (though afaik they've had a lot of problems with Alchemist, and seem to have prioritized Windows performance over Linux for them).
