For Nvidia, I would try Vulkan first, then OGL, then DX11 if I was testing for performance, since Vulkan is newer, there may be some regressions, and DX usually has the most overall problems with dolphin.

And this is the real reason why Vulkan isn't as popular as it should be. AMDs drivers are also way better optimized for Vulkan than OGL, and DX11 performs OK. That's why Nvidia Pascal is very unoptimized for Vulkan. Nvidia on the other hand didn't think new APIs would become a thing in the near future and took a much more pragmatic approach where they'd run the old APIs faster by simply engineering around their limitations rather than trying to eliminate them. Vulkan presents a potential performance increase over DX11 in most cases, though may be slightly less stable for now.

AMD saw that old APIs were eventually going to run into some serious bottlenecks and thought that low level graphics APIs, like the one used in the PS3, were the obvious solution, so they started pushing for them by creating their own low level graphics API and hardware designed for it and other low level APIs. DirectX vs OpenGL Hai th vin ha lâu i nht hin nay. This is very strange because a low-level API has a huge performance advantage in theory. Low-level API's perform sometimes worse than high-level API's on Nvidia architectures. But the problem is that Vulkan doesn't perform the same on Nvidia Pascal. DirectX11 vs DirectX12 vs Vulkan on AMD hardware So with this performance almost every AAA developer would pick Vulkan instead of DirectX11. During heavy workloads you will have 50% less FPS with DirectX11. AMD RX Vega cards run significantly better with Vulkan than with DirectX11. The most important reason is the performance on Nvidia graphics cards.

That's correct but I don't think that these things are an important reason why so many AAA pc games still use DirectX11 instead of Vulkan.
