look like the following:
Software driver
Effect support:

Gooch shader: Software emulation only
Per-pixel lighting: Not applicable
Full-shadow display: Not applicable
Texture compression: Not applicable
Advanced material effects: Not applicable
Autodesk driver: Certified
Effect support:
Enhanced 3D Performance: Available
Smooth display: Available
Gooch shader: Available
Per-pixel lighting: Available
Full-shadow display: Available
Texture compression: Available
Advanced material effects: Available
NOTE To display mapped object shadows in viewports and to use per-pixel
lighting, hardware acceleration is required. When Enhanced 3D Performance is
off, mapped object shadows cannot be displayed in viewports. (To access these
settings, enter graphicsconfig at the Command prompt.)
NOTE When Texture Compression is turned on, the amount of video memory
required to open a drawing that contains materials with images or has attached
images is decreased. By using the effect it can reduce the amount of video memory
necessary to display the drawing, but the downside to this effect is it may increase
the time it takes to load the images the first time that they are accessed. Also,
there is a reduction in the quality of the images when they are displayed in the
viewport or plotted. (To access these settings, enter graphicsconfig at the
Command prompt.)
Certification Updates
As more graphics cards and 3D display drivers are tested, they are added to a
list on the Autodesk website. You can check for updates and download the
latest list at any time. In the Adaptive Degradation and Performance Tuning
dialog box, click Check for Updates.
