vulkan vs DirectX

[TkSilver]

D3d12 needs people (gamers) to actually want to be on Windows 10 since Windows 7 still has over half the Windows market. Until that changes developers will mainly use d3d11 (since it is universal to the last 3 Windows OS) and OpenGL or Vulkan depending on the game, because why shoot off one of your own legs right before a race. With limited developers making d3d12 games there will be less bug fixes and optimizations because there is less data. So there will be less compelling reasons to need to use d3d12 and less reasons to switch to Win10.

Basically it is Vista and d3d10 all over again.

Vulkan supports basically everything it can (non proprietary to an OS for the win) and due to that it evolves at a faster pace and can have an immediate higher adoption rate then any DirectX could. Though it is still very early compared to d3d11, so it will take a while to get to the same maturity and stability (assuming they don't screw up royally and kill it along the way).
