上周发布的Visual Studio 2008 “Orcas” Beta 2的一份Readme文件中提到了Vista SP1 beta，不幸的是，对于一小部分具有运行SP1资格的人们来说，它们在安装Orcas时会有问题。可能是SP1中的.NET Framework 3.0版本的问题，原文如下：
“When Orcas is installed on a Windows Vista SP1 Beta platform, the .Net Framework has mismatched versions. This causes random failures in the product.”
DirectX SDK中写到Direct3D 10.1 Tech Preview将于Direct3D 10.0并肩更新，提供一系列即将来临的图形硬件所具有的新渲染功能。：
* TextureCube Arrays which are dynamically indexable in shader code.
* An updated shader model (shader model 4.1).
* The ability to select the MSAA sample pattern for a resource from a palette of patterns, and retrieve the corresponding sample positions.
* The ability to render to block-compressed textures.
* More flexibility with respect to copying of resources.
* Support for blending on all unorm and snorm formats.
8月份的Direct3D 10.1中包含部分功能和少数新API的预览版，它要求Windows Vista SP1 Beta，并指出MSDN订户可以在SP1 Beta公开发布时得到它。但是，还不确定MSDN用户是首先获取，还是在公开Beta期间与普通用户同时获得。
