![]() ![]() Perhaps the real story here is that Sony rushed Microsoft with the PS4, so Microsoft had to develop Direct3D 11.x as an ‘inbetween’ API until Windows 10 and DirectX 12 were ready, because they couldn’t afford to delay the Xbox One until they were ready. This clearly implies that the ideas behind DX12 existed prior to the development of the Xbox One, and probably the ideas of using a single OS and API on all devices, from phones to desktops to game consoles (we already saw this trend with Windows 8.x/RT/Phone). We knew what DX12 was doing when we built Xbox One. But, since DX12 is released together with Windows 10 and WDDM 2.0, AMD is really claiming that they triggered Microsoft to rush Windows 10.Īlso, since WDDM 2.0 is quite a big overhaul of the driver system, and both Windows 10 and DirectX 12 are built around this new driver system, Microsoft would have had to work out WDDM 2.0 first, before they could design the DirectX 12 runtime on top of it.Īn interesting tweet in this context is by Microsoft’s Phil Spencer: Now, if we revisit AMD and Mantle, their claims were that introducing Mantle triggered Microsoft to work on DirectX 12. So, this has more or less been the pattern since 2006. Well, DirectX 12 is launched, together with a new version of Windows (Windows 10) and an improved driver system (WDDM 2.0). ![]()
