AutoCAD 2008 includes support for Microsoft® Direct3D® hardware acceleration providing more flexibility for video cards. You can specify Direct3D or OpenGL® hardware acceleration in the Manual Performance Tuning dialog box which is accessible using the 3DCONFIG command. Regardless of which option you select for hardware acceleration, new texture compression enhancements will require less video memory and improve performance when display images and textures.
You can learn more about the graphics hardware that can take advantage of the new real-time 3D shading, shadows, and smooth-line display features in AutoCAD 2008 based products at http://www.autodesk.com/autocad-graphicscard.
