During its Gamefest 2008 developer conference in Seattle, Microsoft not only made the multiplayer component in Games for Windows a free service
but also revealed details concerning DirectX 11, the latest edition of its PC gaming graphics API.
Like its predecessor, DirectX 11 will be exclusive to Windows Vista and future versions of Microsoft’s operating system. Features include
a new compute shader technology that lays the groundwork for developers to utilize video cards as parallel processors, as well as improved multi-core support and support for tessellation, which supposedly improves the appearance of close-in models.
Microsoft also revealed that the new software will add features to existing DirectX 10-compatible hardware, though it was not clear what those features may be. Don't go tossing your DirectX 10 card just yet, however, as DirectX will be available sometime in 2009-2010 when the next version of Windows ships.
