Microsoft Ships Final Release of DirectX 6.0

REDMOND, Wash., Aug. 7, 1998 — Microsoft Corp. today announced shipment of the final version of the Microsoft® DirectX® 6.0 Software Development Kit, delivered to developers in time for them to utilize its features in games for the 1998 holiday season.

A mature set of Windows® -based system services, DirectX now provides a single development platform that transparently supports all consumer graphics, audio and input devices and provides faster performance, increased stability and compatibility with today’s multimedia and gaming hardware add-ons. In addition, DirectX 6.0 APIs reduce development time by giving developers access to specialized hardware features without their having to write hardware-specific code. DirectX enables the best multimedia experience on all Windows platforms, making Windows a leading platform for multimedia innovation.

“With DirectX 6.0, Microsoft delivers on its promise to make Windows the best platform for the most innovative multimedia,”
said Kevin Bachus, product manager of DirectX at Microsoft.
“Consumers will reap the benefits of DirectX 6.0 in the new and enhanced products that developers will deliver in the upcoming holiday season.”

DirectX 6.0 Boosts Multimedia Performance for Windows Platforms

Now integrated into Windows 98 and upcoming Windows NT® 5.0 operating systems, DirectX offers better graphics, faster frame rates and enhanced playability. Users can enjoy DVD playback, better audio capabilities, multimonitor support and Universal Serial Bus (USB) for true Plug and Play for joysticks, speakers, keyboards, pointing devices and scanners.

Developers using DirectX 6.0 gain a single set of DirectX APIs for Windows 98, Windows NT 5.0 and Windows 95, making it easier for them to develop for multiple Windows platforms. DirectX 6.0 is also backward-compatible, so applications developed for DirectX 5.0 or earlier versions of the technology will run without compatibility issues.

New DirectMusic, Improved Direct3D Lead DirectX 6.0 Enhancements

DirectX 6.0 includes a broad range of enhancements led by the addition of the new DirectMusic
™API and by improvements to the Direct3D® API.

  • DirectMusic is a new API set that delivers superior music to the Windows platform. It features the following:

  • Better MIDI sequencing for higher-quality playback

  • Support for the MIDI Manufacturers Association’s DownLoadable Sounds (DLS) standards, which let developers add customized instruments to the latest sound cards

  • A high-quality, low-overhead software synthesizer

  • Interactive music composition, which allows a player to make music playback more intense, more dramatic or more exciting in real time

DirectMusic will ship to end users in the fall as part of an update to DirectX 6.0 and is supported today in the DirectX 6.0 Software Development Kit so developers can enable support for DirectMusic in forthcoming titles.

  • Direct3D includes several new, enhanced features, including the following:

  • Significantly faster performance thanks to overall improvements to the run-time components in Direct3D

  • A completely rewritten geometry engine, which is responsible for transform and lighting operations and includes processor-specific optimizations that take advantage of features in the latest generation of CPUs

  • All-new software rasterizers, which enable developers to compare the visual quality of output on 3-D hardware accelerators to a reference standard

  • Support for many new hardware features, including single-pass multitexturing, bump mapping, texture compression, stencil buffers, w-buffers and much more

“The installed base of 3-D-enabled computers will exceed 100 million by year end. DirectX 6.0 is a significant development that will enable the 3-D display capabilities and improve performance of those computers,”
said Jon Peddie, president of Tiburon, Calif.-based Jon Peddie Associates, a leading multimedia consulting firm.
“This type of improvement is what consumers and suppliers have been asking for. By increasing the power and multimedia capability, the market will be opened up, enabling suppliers to reach the broadest audience of consumers. That translates into a win-win situation for the industry and its customers.”

Microsoft has also delivered many other enhancements to the DirectX API suite, including faster performance in the DirectDraw® and DirectSound® APIs and new lobbying services and support for firewalls in the DirectPlay® API.

Meltdown ’98 Event Expands on Major Momentum for DirectX

In addition to Microsoft’s internal compatibility and performance testing process, DirectX 6.0 has been subjected to rigorous testing by the industry, including the semiannual Meltdown event, an intense week of testing, debugging and information sharing about DirectX. More than 600 leading hardware and software developers attended Meltdown ’98 events held in the United States, England and Japan. These Meltdown sessions for DirectX 6.0 have been conducted to ensure that hundreds of titles and an extensive range of hardware will be available by the holiday 1998 selling season.


The DirectX 6.0 SDK is available for download for a limited time at and can be ordered on the Web at The DirectX 6.0 SDK will also be made available as part of the Microsoft Platform SDK in an upcoming release of the Microsoft Developer Network (MSDN
) developer program. Consumers can upgrade to the latest version of DirectX at .
