Microsoft DirectX 10 logo wordmark

A major update to DirectX API, DirectX 10 ships with and is only available with Windows Vista and later; previous versions of Windows such as Windows XP are not able to run DirectX 10-exclusive applications. Rather, programs that are run on a Windows XP system with DirectX 10 hardware simply resort to the DirectX 9.0c code path, the latest available for Windows XP computers.

Changes for DirectX 10 were extensive. Many former parts of DirectX API were deprecated in the latest DirectX SDK and are preserved for compatibility only: DirectInput was deprecated in favor of XInput, DirectSound was deprecated in favor of the Cross-platform Audio Creation Tool system (XACT) and additionally lost support for hardware accelerated audio, since the Vista audio stack renders sound in software on the CPU. The DirectPlay DPLAY.DLL was also removed and was replaced with dplayx.dll; games that rely on this DLL must duplicate it and rename it to dplay.dll.

In order to achieve backwards compatibility, DirectX in Windows Vista contains several versions of Direct3D:

Direct3D 9: emulates Direct3D 9 behavior as it was on Windows XP. Details and advantages of Vista's Windows Display Driver Model are hidden from the application if WDDM drivers are installed. This is the only API available if there are only XP graphic drivers (XDDM) installed, after an upgrade to Vista for example.

Direct3D 9Ex (known internally during Windows Vista development as 9.0L or 9.L): allows full access to the new capabilities of WDDM (if WDDM drivers are installed) while maintaining compatibility for existing Direct3D applications. The Windows Aero user interface relies on D3D 9Ex.

Direct3D 10: Designed around the new driver model in Windows Vista and featuring a number of improvements to rendering capabilities and flexibility, including Shader Model 4.

Direct3D 10.1 is an incremental update of Direct3D 10.0 which shipped with, and required, Windows Vista Service Pack 1. This release mainly sets a few more image quality standards for graphics vendors, while giving developers more control over image quality.[19] It also adds support for cube map arrays, separate blend modes per-MRT, coverage mask export from a pixel shader, ability to run pixel shader per sample, access to multi-sampled depth buffers[20] and requires that the video card supports Shader Model 4.1 or higher and 32-bit floating-point operations. Direct3D 10.1 still fully supports Direct3D 10 hardware, but in order to utilize all of the new features, updated hardware is required.

Microsoft unveiled DirectX 11 at the Gamefest 08 event in Seattle, with the major scheduled features including GPGPU support (DirectCompute), and Direct3D 11 with tessellation support and improved multi-threading support to assist video game developers in developing games that better utilize multi-core processors. Direct3D 11 runs on Windows Vista, Windows 7, Windows 8 and Windows 10. Parts of the new API such as multi-threaded resource handling can be supported on Direct3D 9/10/10.1-class hardware. Hardware tessellation and Shader Model 5.0 require Direct3D 11 supporting hardware. Microsoft has since released the Direct3D 11 Technical Preview. Direct3D 11 is a strict superset of Direct3D 10.1 — all hardware and API features of version 10.1 are retained, and new features are added only when necessary for exposing new functionality. This helps to keep backwards compatibility with previous versions of DirectX.

Microsoft released the Final Platform Update for Windows Vista on October 27, 2009, which was 5 days after the initial release of Windows 7 (launched with Direct3D 11 as a base standard).

DirectX 11.1 is included in Windows 8. It supports WDDM 1.2 for increased performance, features improved integration of Direct2D (now at version 1.1), Direct3D, and DirectCompute, and includes DirectXMath, XAudio2, and XInput libraries from the XNA framework. It also features stereoscopic 3D support for gaming and video. DirectX 11.1 was also partially backported to Windows 7, via the Windows 7 platform update.

DirectX 11.2 is included in Windows 8.1 (including the RT version) and Windows Server 2012 R2. It added some new features to Direct2D like geometry realizations. It also added swap chain composition, which allows some elements of the scene to be rendered at lower resolutions and then composited via hardware overlay with other parts rendered at higher resolution.

DirectX 11.X is a superset of DirectX 11.2 running on the Xbox One. It actually includes some features, such as draw bundles, that were later announced as part of DirectX 12.

DirectX 11.3 was announced along with DirectX 12 at GDC and will be released in 2015. It is meant to complement DirectX 12 as a higher-level alternative.

DirectX 12 was announced by Microsoft at GDC on March 20, 2014, and was officially launched alongside Windows 10 on July 29, 2015. DirectX 12 APIs are also expected to feature on the Xbox One and Windows Phone. The version of DirectX that runs on the Xbox One, DirectX 11.X, already includes a subset of the features in DirectX 12. However, the DirectX 12 code is not intended to be directly portable between PC and Xbox One due to inherent differences between the two platforms. Microsoft has stated that the performance improvements of DirectX 12 on the Xbox One will not be as substantial as that on the PC.

The primary feature highlight for the new release of DirectX was the introduction of advanced low-level programming APIs for Direct3D 12 which can reduce driver overhead. Developers are now able to implement their own command lists and buffers to the GPU, allowing for more efficient resource utilization through parallel computation. Lead developer Max McMullen stated that the main goal of Direct3D 12 is to achieve "console-level efficiency on phone, tablet and PC". The release of Direct3D 12 comes alongside other initiatives for low-overhead graphics APIs including AMD's Mantle for AMD graphics cards, Apple's Metal for iOS and macOS and Khronos Group's cross-platform Vulkan.

Multiadapter support will feature in DirectX 12 allowing developers to utilize multiple GPUs on a system simultaneously, multi-GPU support was previously dependent on vendor implementations such as AMD CrossFireX or NVIDIA SLI.

Implicit Multiadapter support will work in a similar manner to previous versions of DirectX where frames are rendered alternately across linked GPUs of similar compute-power.

Explicit Multiadapter will provide two distinct API patterns to developers. Linked GPUs will allow DirectX to view graphics cards in SLI or CrossFireX as a single GPU and use the combined resources. Whereas Unlinked GPUs will allow GPUs from different vendors to be utilized by DirectX, such as supplementing the dedicated GPU with the integrated GPU on the CPU, or combining AMD and NVIDIA cards. However, elaborate mixed multi-GPU setups requires significantly more attentive developer support.

DirectX 12 is supported on all Fermi and later Nvidia GPUs, on AMD's GCN-based chips and on Intel's Haswell and later processors' graphics units.

At SIGGRAPH 2014, Intel released a demo showing a computer generated asteroid field, in which DirectX 12 was claimed to be 50%-70% more efficient than DirectX 11 in rendering speed and CPU power consumption.

Ashes of the Singularity was the first publicly available game to utilize DirectX 12. Testing by Ars Technica in August 2015 revealed slight performance regressions in DirectX 12 over DirectX 11 mode for the Nvidia GeForce 980 Ti, whereas the AMD Radeon R9 290x achieved consistent performance improvements of up to 70% under DirectX 12, in some scenarios the AMD outperformed the more powerful Nvidia under DirectX 12. The performance discrepancies may be due to poor Nvidia driver optimizations for DirectX 12, or even hardware limitations of the card which was optimized for DirectX 11 serial execution, however the exact cause remains unclear
