It's even neck in neck in titles where Nvidia paid the developers to trash the console optimized path (which would have been ported as an identical DX12 path), and write an entirely new, much slower, DX11 path. Why? Because Nvidia's DX12/Vulkan-style path in the driver is absolute trash, while their DX11/OGL4-era path is very well tuned. Nvidia's "advantage" is entirely software, the emperor wears no clothes. With games that Nvidia's money couldn't cripple games, the 7900XTX, the card that both costs less and uses less watts, beats the 4090 in 1080p, 1440p, and 4k targets.
