Additional InformationThis section contains the following: What's New in the October 2006 DirectX SDK This version of the DirectX SDK contains the following new features, tools, and documentation. PIX: HLSL Shader Debugging in Direct3D 9 Using PIX, you can now debug HLSL pixel shaders and vertex shaders in the context of your game. The shader debugger can be started from either the pixel history view or from the mesh viewer. Using the debugger, you can step through the code (forward and backward), stop on the cursor or user-set breakpoints, and add highlights to syntax to make the code easier to read. Preview Release of the new HLSL Shader Compiler for Direct3D 9 Targets This release has a beta version of d3dx9d_31_beta.dll that includes the Direct3D 10 HLSL compiler enabled for Direct3D 9 targets (shader models 2.0 and later). The new compiler has no support for 1_x targets. This debug-only DLL allows developers to utilize the new Direct3D 10 HLSL compiler for their Direct3D 9 shaders, and will become the default compiler for all Direct3D shaders. Please try the new compiler by building your application with d3dx9d_31_beta.dll instead of d3dx9d_31.dll. For developers using Direct3D 9, the beta DLL provides a programmatic way of using the shader compiler, FXC10.exe, that ships as part of the Direct3D 10 Technology Preview. It is important to note that this library is still in the beta stage of development. If you have any questions, bugs reports, or feedback, please contact directx@microsoft.com. Usability Improvements in XACT Several usability features have been added to XACT. One such notable feature is that waves in a wavebank that are unused by any sounds are highlighted in red and italics, making it easy to identify those waves that can be removed. Improved Control of Chart Quality Using UVAtlas Functions The Direct3DX DLL has been updated with several improvements. Notably, both D3DXUVAtlasCreate and D3DXUVAtlasPartition now have an additional parameter, dwOptions, that allows developers to control the quality of the generated charts. The file name of the updated DLL is d3dx9_31.dll. XInput The XInput DLL has been updated with a new function, XInputGetKeystroke. This function provides a more general way of getting input data than using XInputGetState. Additionally, the file name of the updated DLL is xinput1_3.dll. Known Issues with the October 2006 SDK Managed DirectX 2.0 Beta Removed In the October 2006 SDK, the Managed DirectX 2.0 Beta has been removed and is no longer supported. There are two distinct paths for developers migrating from Managed DirectX 2.0. If you are currently using Managed DirectX 2.0 for tool, editors, or other applications that require specific Direct3D, Direct3DX, DirectSound, or DirectInput functionality, you should migrate to the Managed DirectX 1.1 runtime. Managed DirectX 1.1 is completely compatible with the .NET Framework 2.0 and will not require you to change the version of the CLR. If you are planning to release a game using the .NET Framework, it is recommended that you adopt XNA Game Studio Express, currently in beta. XNA Game Studio Express uses the XNA Framework which is very similar to Manged DirectX in many respects. XNA Game Studio Express is scheduled for release before the end of 2006. This first release is targeted at hobbyists developers and students. If you have any questions, comments, and/or concerns please contact xna@microsoft.com. DirectX Control Panel Removed from the Microsoft Control Panel In the August 2006 and later SDKs, the DirectX® Control Panel has been removed from the Microsoft® Control Panel. You can now find the DirectX Control Panel in the Start menu under All Programs, Microsoft DirectX SDK, DirectX Utilities. In addition, the control panel executable has been renamed from directx.cpl to dxcpl.exe; it can be found in both the %DXSDK_DIR%\utilities\bin\x64 and %DXSDK_DIR%\utilities\bin\x86 folders. Signature Change: D3DXUVAtlasCreate and D3DXUVAtlasPartition In the October 2006 SDK, a new parameter, dwOptions, was added to D3DXUVAtlasCreate and D3DXUVAtlasPartition. This parameter allows developers to control the quality of the generated charts. Preview Version of the New HLSL Shader Compiler for Direct3D 9 Targets: No Support for 1.x Pixel Shader Targets The October 2006 SDK includes d3dx9d_31_beta.dll. This debug DLL includes the Direct3D 10 HLSL compiler enabled for Direct3D 9 targets (shader models 2.0 and later). The new compiler has no support for 1.x pixel shader targets. In a future release, the new compiler will become the default for Direct3D 9. As a result, all developers are encouraged to author their shaders in HLSL and use shader models 2.0 and higher. The new compiler exposed through the beta DLL also has the following issues:
Direct3D 10 Technology Preview Windows Vista RC1 Is Required for the Direct3D Technology Preview The October 2006 Direct3D® 10 Technology Preview is only supported on Windows Vista™ RC1 (build 5600). Direct3D HLSL Compilation Issues In the August 2006 and later SDKs, there are several issues related to the new HLSL compiler, fxc10.exe:
Displacement Mapping Sample Renders Incorrectly In the October 2006 SDK, the Displacement Mapping sample for Direct3D 10 renders incorrectly due to a bad displacement map texture. This issue will be fixed in a future release of the SDK. Per-Sample Readback of MSAA Render Targets in the Shader Not Supported in the Reference Rasterizer In the August 2006 and later SDKs, per-sample readback of MSAA render targets in the shader is not yet supported by the Direct3D 10 reference rasterizer. This issue will be fixed in a future release of the SDK. DXGI: Cross-Process Shared Surfaces Not Supported in the Reference Rasterizer In the August 2006 and later SDKs, cross-process shared surfaces are not supported when using the Reference Rasterizer. This issue will be fixed in a future release of the SDK. PIX for Windows In the August 2006 and later SDKs, PIX has the following issues:
Microsoft Cross-Platform Audio Creation Tool (XACT) In the August 2006 and later SDKs, the Microsoft Cross-Platform Audio Creation Tool (XACT) has the following issues:
In the August 2006 and later SDKs, the shader debugging functionality of the DirectX Extensions for Visual Studio® does not work with Visual Studio 2005. (Syntax highlighting continues to work with Visual Studio 2005.) XInput When XInputGetState is used to retrieve controller data, the left and right triggers are each reported separately. For legacy reasons, when DirectInput® retrieves controller data, the two triggers share the same axis. The legacy behavior is noticeable in the current Game Device Control Panel, which uses DirectInput for controller state. Installation Notes for All Platforms
Installation Notes for Vista RC1 Running Microsoft_DirectX_SDK.msi instead of setup.exe requires "Run As Administrator" to work correctly. If you install using setup.exe instead of using the MSI, you will be prompted for elevated permissions before the installation can succeed. This release does not install any Developer Runtime components on earlier versions of Windows Vista. If you are running Windows Vista Beta 2 (or earlier) and you need Developer Runtime components, you can use older releases of the DirectX SDK. Or you can copy the components that you need (debug DLLs and symbols) from "checked" builds of Vista. All release versions of D3DX and the latest debug version are installed on all versions of Windows Vista.
