DirectX 10 will be Vista-only
WinInfo | at | by Mike
Microsoft confirmed this week that the upcoming version of Microsoft's gaming libraries--dubbed DirectX 10--will be made available only to Windows Vista users. DirectX 10 will eventually be supported by hardware--typically 3D video cards--that will work on Windows XP, although it won't have any DX10-specific features. All DirectX 10 games that are released in the future will be Vista-specific. My guess is that we won't be seeing very many of them for quite a while. And here's a fun fact: Although the upcoming Windows version of Halo 2 will be created with DirectX 9.0, it will be artificially limited to running on Vista. You know, so you have at least one reason to upgrade.
