Los Angeles, here I come again. The conference is WinHEC 2007, and this time I'll be participating as a speaker, presenting an overview of the graphics architecture in Windows Vista. For people who have seen the graphics overview presentation last year, this year's presentation will be largely a recap. If you haven't seen it, however, it's a good way to wrap one's mind around the various graphics technologies in Windows, from display drivers to the Windows Presentation Foundation and other high-level rendering technologies.
