directX9 vs 11 vs openGL vs vulkan

[Zalto]

I have rounded them up:
directx11: 58
opengl: 50
vulkan: 56
directx9: 60

the specs arent really important. What is, is why is directX9 is higher. I though that directx11 was supposed to be better.

I dont really get the difference between those four except that directX 11 is the evolution of 9. Can someone enlighten me on that please

In short:
DX9-12 are Microsoft's APIs and so bound to Windows.
OpenGL/Vulkan are Khronos group's APIs and are available on multiple OSes.

DX12 & Vulkan are newest APIs and are quite similar, but require much more work from developers. They should be fastest APIs once drivers and games would be optimized, which can take time.
Vulkan is already faster than OpenGL. It's main reason to use it on Linux.
Also Vulkan uses noticeably less CPU.

Thanks to enlighten me on those two different API. I can see that Vulkan is faster than openGL.

Though I still dont get why is DirectX 9 has higher FPS in the benchmark than DirectX 11. My drivers are all up to date so I just dont get it.

You haven't shared your system specs so I cannot comment much on FPSes that you've got... :(

i have more fps in dx11, in dx9 its a bit less

btw listing fps results alone are totally irrevelant without PC specs and ingame settings+resoluton+OS

I made some test just to check, my specs are:

AMD Phenom II x4 @ 3.8
8GB Ram DDR3 1600Mhz
AMD HD 7970Ghz

Wanted to check Vulkan and stuff, the game looks pretty similar, either way I get 60fps so I didin't mind that, the only thing I noticed is that under Vulkan I cannot see the Steam Overlay, it has no backgrounds and all the letters are squared symbols. Certainly adds some immersion to the whole game.
