Dec 02, 2020 DirectX 12. Shader Model 5.1 Support for Shader Models began with DirectX 8.0. Windows XP does not support DirectX 10.0 and higher, and Windows Vista and Windows 7 (before Service Pack 1) do not support DirectX 11.0 or higher.
This download provides drivers for the Intel Integrated Graphics in Intel Processors like Core i3, Core i5, Core i7 and Core i9. These Intel Graphics Drivers also provide support for the IGP included with all recent Pentium and Celeron processors. Supported processor architectures are: Tiger Lake, Comet Lake, Coffee Lake, Kaby Lake and Skylake.

DirectX 9.0c includes support for Pixel Shader and Vertex Shader 3.0, along with many new features across all technologies, which can be accessed by applications using DirectX.

DirectX 9 Features include:

Multi-Threading: The ability to scale across multi-core CPUs will enable developers to take greater advantage of the power within multi-core CPUs. This results in faster framerates for games, while still supporting the increased visual detailing.
DirectCompute: Developers can utilize the power of discrete graphics cards to accelerate both gaming and non-gaming applications. This improves graphics, while also enabling players to accelerate everyday tasks, like video editing, on their Windows 7 PC.

Windows 7 comes with a newer version of DirectX but is fully compatible with all of the new features of DirectX 9.0c. Additionally, in order to take advantage of the features of DirectX, you must ensure that you have installed a DirectX compliant video card.

If you're wanting an even newer version, DirectX 10 is also available. This version is the download of the redistributable version. That means it may be included in software packages or just simply used freely by anyone wishing to update their DirectX version on Windows XP or Windows 7 (32-bit).

This package contains the DirectX 9.0c installer for Windows XP, the installer for Windows 7 and is compatible with the DirectX 9 redistributable from February 2010 and June 2010. This web installer package works with DirectX 9 graphics devices with WDDM 1.0 or higher drivers. In case you run into issues when installing this package, you may have an older video card that is not compatible with DirectX 9.0c.

The DirectX 9 SDK is also available for download from this site (use the search function).

Please note: If you are using Windows 7 and a game or other programs requires you to have DirectX 9.0c compatible video or audio driver installed, you should check to see whether there is a patch available for the game or program you have installed. In some cases, simply installing updated drivers for your video or audio card solves the problem. If updating drivers doesn't help, running the program in compatibility mode may.

DirectX 9.0c on 32-bit and 64-bit PCs

This download is licensed as freeware for the Windows (32-bit and 64-bit) operating system on a laptop or desktop PC from components without restrictions. DirectX 9.0C 9.0c is available to all software users as a free download for Windows 10 PCs but also without a hitch on Windows 7 and Windows 8.

Compatibility with this software may vary, but will generally run fine under Microsoft Windows 10, Windows 8, Windows 8.1, Windows 7, Windows Vista and Windows XP on either a 32-bit or 64-bit setup. A separate x64 version may be available from Microsoft.

This topic provides details about new features and enhancements in Windows Display Driver Model (WDDM) version 2.1, which is available starting with the Windows 10 Anniversary Edition.

WDDM 2.1 itself is optional. If implemented, it is a collection of mandatory and optional driver capabilities. Any driver which supports any of those capabilities must support all of the mandatory ones. Support can be validated by HLK tests, but Dxgkrnl will check for consistency in the capabilities and DDIs.

WDDM 2.1 Requirements Table

Feature	Applicability
Offer and reclaim improvements	Mandatory
Video memory management	Optional
HW protected content reliability improvements	Select Hardware
Application support with Windows GameDVR	Mandatory
Indirect display	Select Hardware
Driver store and side-by-side installation	Mandatory
DirectX memory surface sharing for camera/capture scenarios	Mandatory

WDDM 2.1 supports the following D3D versions: D3D9, D3D10, D3D10.1, D3D11, D3D11.x, D3D12

Offer and reclaim improvements

A new DDI, PFND3DDDI_RECLAIMALLOCATIONS3CB was created to reduce memory footprint of applications running in background mode. This interface will enable applications to offer resources that are acceptable to fully de-commit, when going into the background. As a result, the Process Lifetime Manager will be able to reclaim more memory from background apps that use DirectX, which leads to less background application terminations when under memory pressure.

Other DDI changes:

For more information about offer and reclaim resources, see Offer and reclaim changes.

Application support with Windows GameDVR

Windows 10 Anniversary edition includes improved ability to use the Windows game bar and GameDVR with full screen games.

WDDM 2.1 drivers are required to support a performance feature called present batching, which adds multi-threading support for flip model swapchains. This is an essential feature that ensures that full screen games with game bar run at the same level of performance as on earlier versions of Windows.

The following lists the new DDIs created to enable this feature:

Indirect Display

In WDDM 2.1, Indirect Display enables USB connected displays to participate in all the same user experiences as any other monitor. In addition, an Indirect Display driver is a User Mode driver, which is simpler to develop than a kernel mode driver, and as a result contributes to increased overall system reliability.

In WDDM 2.1, the following USB display features/experiences are enabled:

When connecting a USB display to a Windows platform or upgrading operating systems, the proper drivers will be downloaded and installed from Windows update.
Connecting monitors to USB display hardware will detect and set the correct monitor topology, resolution and DPI.
Users can change monitor resolution and scaling on the monitor.
Users can disconnect USB displays and reconnect displays without unexpected side effects.
Monitor topology is retained through disconnect and reconnect to the same monitor.
USB displays functions properly in various power states including sleep and hibernation.

For more information about indirect display, see Indirect Display Driver Model Overview

Driver Store and Side-by-Side driver installation

WDDM 2.1 introduces installation of graphics drivers through the driver store. This mechanism of installing graphics drivers improves the resiliency of driver updates from Windows Update, eliminating driver file version mismatches resulting in system instabilities and user initiated reboots. Each subsequent driver update will be run directly from its unique location in the driver store (i.e. System32DriverStoreFileRepository[…]), thus avoiding driver file overwrites and mismatches.

Feature implementation of driver store requires changes to the graphics driver INF file in order to ensure that the driver files get copied to the unique driver repository. The INF changes are explained in more details in the INF Requirements section in this document.

DXIL

WDDM 2.1 introduces the transition of the GPU shader compiler stack from DirectX Byte Code (DXBC) to DirectX Intermediate Language (DXIL), a new format for transmitting shader instructions to the GPU. Transition to DXIL delivers the following benefits to developers:

Programmability - Ease-of-development is improved and complexity of the shader creation process
