Why do you guys not properly supporting DX12?

old hardware with windows 10 support dx12.

old hardware don't properly support valkun.

Because it is a dead end that only works on one operating system.

Old hardware is not relevant, too slow anyway.

I get the point.but
Most pc & laptop users are using intel igpu in the world. igpu doing good job at 720p &
DX12 run much better then valkun on intel gpu.

Anyway, just wanted to know.

It would be more wise to make that hardware support Vulkan instead.

Dolphin team made recently similar decision, they deprecated dx12 backend in favour for vulkan one. Nowadays emulators share some code, and devs make similar decisions. Vulkan is multiplatform vs dx12 which works only on one OS. Still, even opengl is valuable if developer knows how to code for fast execution. One example after latest actualization of intel drivers, i got proper support for opengl 4.5 and vulkan too on my kabylake. Cemu emulator on HD 620 in opengl mode playing mario kart gives 60fps output. Could you even imagine that?

49.04% of all Personal Computers in the world run Windows 7 - DX12 - No,Vulkan - Yes
Windows 10 is only 26.8% - DX12 - Yes,Vulkan - Yes.
Linux,Mac OS X,Windows XP,Windows Vista,Windows 8,Windows 8.1 - 20.56% - DX12 - No,Vulkan - Yes
69.6% of the Personal Computers in the world Do Not Support DX12,but support Vulkan.
(True to June 2017 OS market share)

It doesn't worth the effort to develop with DX12,
Vulkan supports almost all OS'es,Including Android.
The only games that support DX12 only are Microsoft's games...
Both are based on the Mantle API anyway.

why opengl has wrong color match ? i mean yellow tint is more in opengl other than DX12.

These statistics seem just plain wrong.
Let's take a more appropriate test for this situation: Steam Hardware & Software Survey. People that use emulators also often use Steam, so this is a more reliable test than some random OS market share test.

50% of users use Windows 10 x64, followed by 32% Windows 7 x64.
It's not a surprise since Microsoft shoved down the update for Windows 10 the way they did.

Anyways, D3D12 is irrelevant because it only supports one OS. Vulkan allows for the same performance gains, so Vulkan is supported instead.

If D3D12 ever gets improved one day, it's only having old hardware in mind. But old hardware will have trouble running games properly anyways, so..
