A default diagnostics tool included in Windows 7 can incorrectly report DirectX 11 devices as DirectX 10.1, Microsoft has revealed. At fault is the DirectX Diagnostics Tool, the Redmond company explains. The Erroneous reporting of DirectX 11 devices as DirectX 10.1 devices is a problem that also affects Windows Server 2008 R2, the software giant discloses. However, the issue is by no means severe, and in fact easy to fix.

“When you run the DirectX Diagnostics Tool (Dxdiag.exe) on a computer that is running Windows 7 or Windows Server 2008 R2, the diagnostic tool incorrectly reports a DirectX 11 device as a DirectX 10.1 device. This incorrect version information is shown in the DDI field on the Display tab. This problem is only a reporting error. This problem does not affect the DirectX 11 hardware or software functionality of the graphics card,” Microsoft explains.

The Redmond company is already offering a hotfix designed to deal with the problem. The fix can be grabbed from Microsoft Support, but the company stresses that only customers affected by this specific issue should apply the resolve. More »

With Windows 7 pre-Beta Build 6801 out of Redmond, it was only natural that DirectX 11 would follow. And this is precisely what happened. Having served Milestone 3 Build of the next iteration of the Windows client, Microsoft is also moving forward with the graphics technology included by default with the operating system. The transition from Vista to Windows 7 is synonymous with the evolution from DirectX 10.1 (in Vista SP1) to DirectX 11. At this point in time, the first taste of the next version of the DirectX suite of multimedia application programming interfaces (APIs), namely DirectX 11, is available for download via the November 2008 DirectX Software Development Kit.

“Included in the November 2008 DirectX SDK is a technical preview of Direct3D 11 and associated components and tools. Direct3D 11 is an update to Direct3D 10.1 enabling new hardware features as well as improving the breadth of configurations supported by Direct3D. As such, Direct3D 11 enables developers to create applications and games that work on Direct3D 10, Direct3D 10.1, and Direct3D 11 hardware when it becomes available. With the addition of WARP and Direct3D 10 Level 9, Direct3D 10.1 and Direct3D 11 have the ability to target fast software rasterization and Direct3D 9 hardware,” Microsoft revealed. More »

August 2008 has been synonymous with three separate releases of DirectX for a variety of Windows operating systems. The DirectX refreshes are tailored to Windows Vista Service Pack 1, Windows XP Service Pack 3 and Windows Server 2008 RTM/SP1, but also to Windows Server 2003.

Microsoft made available for download updated versions of the DirectX Software Development Kit, the DirectX End-User Runtimes, as well as the DirectX End-User Runtime Web Installer. The first two releases have been re-published on the Microsoft Download Center on August 18, 2008, while the last one is available in the same form as when it went live on August 8.

DirectX End-User Runtimes (August 2008) “provides the DirectX end-user multi-languaged redistributable that developers can include with their product. The redistributable license agreement covers the terms under which developers may use the Redistributable. This package is localized into Chinese (Simplified), Chinese (Traditional), Czech, Dutch, French, German, Italian, Japanese, Korean, Polish, Portuguese (Brazil), Russian, Swedish, and English. […] The DirectX redist installation includes all the latest and previous released DirectX runtime. This includes the bi-monthly D3DX, XInput, and Managed DirectX components,” Microsoft informed.

As you undoubtedly know by now, Windows Vista brought to the table DirectX 10. Microsoft failed to make DirectX 10 available for Windows XP, arguing that it would have to introduce extensive changes to the core of the operating system, in order to accommodate the new graphics technology. In this context, Vista became the vessel for DirectX 10, because despite various promises from third-parties to artificially backport DirectX 10 for Windows XP, the latest Windows client remains the sole way to access the superset of DirectX 9.x.

Microsoft touted a healthy increase in gaming and multimedia quality with DirectX 10 as an integer part of Vista’s architecture, but with the vast majority of users still running Windows XP, digital content is largely focused on Vista’s predecessor. The Redmond company was in fact
criticized by both content producers and end users for its decision to make DirectX 10 Vista exclusive, but the barrage of fire failed to deter Microsoft from its tracks. Moreover, in the first quarter of this year, Windows Vista SP1 will deliver DirectX 10.1. More »
