My understanding (and this could be false) is that many games are based on externally developed game engines, such as Unreal and Unity. If these game engines make use of Vulkan (which they are almost bound to do so, CryEngine already has early support) then does it make any difference to the developers of the games? The only thing I could think of where it might matter is if the GPU drivers have better support for DX12 than Vulkan, resulting in better performance, but I have no idea if that's the case.
