The Avalon DWM alters the look and feel of the desktop just a bit. On the surface, the changes don't seem dramatic. The "bugs"—the minimize/maximize/close buttons—at the top right change a bit in appearance. The windows themselves, however, are now individual 3D surfaces. Each window, when layered above another, appears to float on top of the one below, complete with a soft drop shadow. When you hit ALT-TAB to task switch, all the windows suddenly tilt inward and neatly layer. This allows you to see all the windows more clearly.
DWM is not without bugs. The desktop manager is enabled in a DOS shell screen, and resides in \windows\i386. You type "SBCTL Start" to turn on DWM. As soon as you do, all the text and icons in the taskbar disappear, and you're left with a featureless expanse of gray.
These slick, 3D-accelerated features come at a cost, too. Even on our testbed, a 3.2GHz Pentium 4 running a high-end ATI Radeon 9800XT graphics card, the Avalon DWM seemed just a tad sluggish. Additional cool features, like the compositing manager, weren't available yet.
The 3D features require DirectX 9.0, and this version of the OS ships with DirectX 9.0b, unlike the fall preview, which only had DirectX 8. In fact, we were able to run 3DMark 2003 with no problems using the default Radeon 9800XT driver embedded in build 4072. (You can read more about Longhorn's anticipated 3D nature here.)
