WDDM 2.0 is also responsible for some of the baser CPU efficiency optimizations in DX12, such as changes to how memory residency is handled and how DX12 applications can more explicitly control residence. Among the features tied to WDDM 2.0 are DX12вЂ™s explicit memory management and dynamic resource indexing, both of which wouldnвЂ™t have been nearly as performant under WDDM 1.3.

Microsoft has not released too many details on WDDM 2.0 so far вЂ“ more information will be released around GDC 2015 вЂ“ but WDDM 2.0 is based around enabling DirectX 12, adding the necessary features to the kernel and display drivers in order to support the API above it. In fact WDDM 2.0 is the biggest change to WDDM since the driver model was introduced in Windows Vista, and as a result DirectX 12 itself represents a very large overhaul of the Windows GPU ecosystem. Like MicrosoftвЂ™s last couple of DirectX 11 minor version upgrades, DirectX 12 goes hand-in-hand with a new version of the Windows Display Driver Model, WDDM 2.0. But as of now everything is far enough along that we can finally get a reasonable look at what DirectX 12 is capable of.ДЇrom a technical perspective the DirectX 12 API is just one part of a bigger picture.

There are still bugs, and performance and compatibility is subject to change. As a result todayвЂ™s preview should be taken as just that: an early preview. Windows 10 itself is still feature-incomplete, so what weвЂ™re looking at here today doesnвЂ™t even qualify as beta software. The Current State of DirectX 12 & WDDM 2.0ДЄlthough DirectX 12 is up and running in the latest public release of Windows 10, it and many of its related components are still under development.
