Greetings from Brasil!
I was sent the following white paper dealing in-depth with Autodesk products and Microsoft Windows Vista support. It will soon be on the Autodesk website but I have provided a copy for you now.

"Introduction
With the introduction of Microsoft® Windows Vista, Autodesk® customers have another choice of operating systems. Whether a company opts to adopt Windows Vista, Windows® XP, or another supported operating system (OS), Autodesk applications deliver exceptional performance across the board.

To ensure the superlative performance of Autodesk applications on Microsoft operating systems, Autodesk has worked closely with Microsoft over the past 12 years, collaborating on product development, bringing innovative technologies to market, and exceeding customer expectations. As a Microsoft Platinum Partner, a Global ISV, and a member of Microsoft’s Manufacturing ISV program, Autodesk’s close relationship with Microsoft enhances Autodesk’s ability to provide products that raise the bar for innovation and transcend operating systems. Whether companies use Microsoft Vista or Microsoft XP operating systems, Autodesk is committed to delivering solutions that provide the functionality its customers have come to expect.

The close collaborations between Autodesk and Microsoft result in simultaneous support for new technologies, as evidenced by the compatibility of Autodesk applications with Windows Vista and Microsoft’s adoption of the Autodesk DWF file format as a native part of Windows Vista. In addition, Autodesk has chosen the Direct3D graphics application programming interface (API) developed by Microsoft over the alternative OpenGL API. By aligning with Microsoft on Direct3D, Autodesk is delivering a highly positive experience to customers using its products with Windows Vista. For more information on how Direct3D enhances the user experience for graphics-intensive applications, see page 15 of this paper.

While Autodesk believes that Windows Vista will become the industry-standard OS over time, the Autodesk 2008 product line increases design efficiency and cost savings for customers using any supported OS. Companies that plan to deploy Windows Vista this year may have questions about whether their specific Autodesk applications are compatible with Windows Vista and what kinds of performance changes they may expect. This paper addresses Vista compatibility and performance on a product by-product basis, as well as highlights the new functionality of the Autodesk 2008 products.
