DirectX 11 11 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 11 Update 11 is available to all software users as a free download for Windows. We have tested DirectX 11 11 against malware with several.

The SDK includes a number of interesting samples of how to create 3D graphics with Microsoft DirectX 11 including motion blurs, anti-aliasing, FXAA, shadows, filters, etc. NVIDIA Direct3D also includes ocean rendering.

The collection download is rather large and an excellent set of examples on how to code with some of the newer techniques.

When I open facebook on the win10 build application it is showing Direct3D With feature level 93 or greater.What should I do know,it is software problem or anything elses. Moved by Annie Chen-MSFT Thursday, October 12, 2017 2:07 AM not ads-in-apps issue. Wednesday, October 11, 2017 2:23 PM.
Specify user clip planes in HLSL on feature level 9 and higher. Starting with Windows 8, you can use the clipplanes function attribute in an HLSL function declaration rather than SVClipDistance to make your shader work on feature level 9x as well as feature level 10 and higher. For more info, see User clip planes on feature level 9 hardware.

Major release: NVIDIA Direct3D SDK 11.0

-->

The following functionality has been added in Direct3D 11.1, which is included with Windows 8, Windows RT, and Windows Server 2012. Partial support for Direct3D 11.1 is available on Windows 7 and Windows Server 2008 R2 via the Platform Update for Windows 7, which is available through the Platform Update for Windows 7.

Shader tracing and compiler enhancements

Direct3D 11.1 lets you use shader tracing to ensure that your code is performing as intended and if it isn’t you can discover and remedy the problem. The Windows Software Development Kit (SDK) for Windows 8 contains HLSL compiler enhancements. Shader tracing and the HLSL compiler are implemented in D3dcompiler_nn.dll.

The shader tracing API and the enhancements to the HLSL compiler consists of the following methods and functions.

The D3dcompiler.lib library requires D3dcompiler_nn.dll. This DLL is not part of Windows 8; it is in the bin folder of the Windows SDK for Windows 8 along with the Fxc.exe command-line version of the HLSL compiler.

Note

While you can use this library and DLL combination for development, you can't deploy Windows Store apps that use this combination. Therefore, you must instead compile HLSL shaders before you ship your Windows Store app. You can write HLSL compilation binaries to disk, or the compiler can generate headers with static byte arrays that contain the shader blob data. You use the ID3DBlob interface to access the blob data. To develop your Windows Store app, call D3DCompile2 or D3DCompileFromFile to compile the raw HLSL source, and then feed the resulting blob data to Direct3D.

Direct3D device sharing

Direct3D 11.1 enables Direct3D 10 APIs and Direct3D 11 APIs to use one underlying rendering device.

This Direct3D 11.1 feature consists of the following methods and interface.

Check support of new Direct3D 11.1 features and formats

Direct3D 11.1 lets you check for new features that the graphics driver might support and new ways that a format is supported on a device. Microsoft DirectX Graphics Infrastructure (DXGI) 1.2 also specifies new DXGI_FORMAT values.

This Direct3D 11.1 feature consists of the following API.

ID3D11Device::CheckFeatureSupport with D3D11_FEATURE_DATA_D3D11_OPTIONS, D3D11_FEATURE_DATA_ARCHITECTURE_INFO, D3D11_FEATURE_DATA_D3D9_OPTIONS, D3D11_FEATURE_DATA_SHADER_MIN_PRECISION_SUPPORT, and D3D11_FEATURE_DATA_D3D9_SHADOW_SUPPORT structures
ID3D11Device::CheckFormatSupport with D3D11_FORMAT_SUPPORT_DECODER_OUTPUT, D3D11_FORMAT_SUPPORT_VIDEO_PROCESSOR_OUTPUT, D3D11_FORMAT_SUPPORT_VIDEO_PROCESSOR_INPUT, D3D11_FORMAT_SUPPORT_VIDEO_ENCODER, and D3D11_FORMAT_SUPPORT2_OUTPUT_MERGER_LOGIC_OP

Use HLSL minimum precision

Starting with Windows 8, graphics drivers can implement minimum precision HLSL scalar data types by using any precision greater than or equal to their specified bit precision. When your HLSL minimum precision shader code is used on hardware that implements HLSL minimum precision, you use less memory bandwidth and as a result you also use less system power.

You can query for the minimum precision support that the graphics driver provides by calling ID3D11Device::CheckFeatureSupport with the D3D11_FEATURE_SHADER_MIN_PRECISION_SUPPORT value. In this ID3D11Device::CheckFeatureSupport call, pass a pointer to a D3D11_FEATURE_DATA_SHADER_MIN_PRECISION_SUPPORT structure that ID3D11Device::CheckFeatureSupport fills with the minimum precision levels that the driver supports for the pixel shader stage and for other shader stages. The returned info just indicates that the graphics hardware can perform HLSL operations at a lower precision than the standard 32-bit float precision, but doesn’t guarantee that the graphics hardware will actually run at a lower precision.

You don't need to author multiple shaders that do and don't use minimum precision. Instead, create shaders with minimum precision, and the minimum precision variables behave at full 32-bit precision if the graphics driver reports that it doesn't support any minimum precision. For more info about HLSL minimum precision, see Using HLSL minimum precision.

HLSL minimum precision shaders don't work on operating systems earlier than Windows 8.

Specify user clip planes in HLSL on feature level 9 and higher

Starting with Windows 8, you can use the clipplanes function attribute in an HLSL function declaration rather than SV_ClipDistance to make your shader work on feature level 9_x as well as feature level 10 and higher. For more info, see User clip planes on feature level 9 hardware.

Create larger constant buffers than a shader can access

Direct3D 11.1 lets you create constant buffers that are larger than the maximum constant buffer size that a shader can access (4096 32-bit*4-component constants – 64KB)
