It appears that Microsoft is offering DirectX 11.1 to Windows 7 users, thankfully. Well, not DirectX 11.1 in its entirety, but some features which could appease staunch Windows 7 enthusiasts who aren't interested in upgrading to Windows 8. As indicated on MSDN, these are included in the Windows 7 Service Pack 1 through KB 2670838, or what's called as the Platform Update for Windows 7 Service Pack 1 and Windows Server 2008 R2 Service Pack 1. Incidentally, the update also includes the Windows 7 Internet Explorer 10 Release Preview. Those who want to avoid the IE10 preview can also download KB 2670838 as a standalone prerelease update. Unfortunately, the update will be missing WDDM 1.2 as it remains a Windows 8 exclusive - along with the native support for stereoscopic 3D sans the use of third-party software. Here is a list of the features that will be deployed to Windows 7:

  • ID3D11Device1, ID2D1Factory1, IDWriteFactory1, IDXGIFactory2, IWICImagingFactory2, ID3DUserDefinedAnnotation and related APIs are available. Methods that depend on WDDM 1.2 drivers or new Windows Store app APIs are not supported.
  • Improved Direct3D 11 device interoperability via ID3DDeviceContextState, including the improved interop with Direct2D/DirectWrite.
  • D3D11_FEATURE_DATA_D3D9_OPTIONS feature detection.
  • In addition to the new Windows 8 WIC features, this update also fixes decoding of 96bpp floating-point TIFF images.
