I think what is being claimed, but not explicitly in the article, is that this is running the NVIDIA driver stack (for an ancient GeForce 8 card) directly, as opposed to emulating DirectX at the API level on top of a Vulkan driver.
Eh. It's sort of like saying FreeDOS is laughable because DOSBox exists. I think that's missing the point.
