Down to move a selected item up or down in the chain.

Hardware and Performance Tuning
Specifies hardware settings and performance tuning. The performance tuner
reads your system and decides whether to use software or hardware
implementation for features that support both. Features that work with your
system are turned on, and features that cannot work with your system are
turned off. A log file displays the results. You can make manual changes.

Get Download Info This button is displayed after you have checked for
updates and when a new driver is available and recommended.
Displays a Web page that describes the certification program for graphics cards
and display drivers. You can download the latest list of certified cards and
drivers at any time.
Graphics hardware certification indicates which graphics card and driver
combinations that Autodesk has tested to ensure that it supports real-time 3D
shading, shadows, smooth-line display, and texture compression features of
AutoCAD 2007 (and later) based products. Autodesk certified graphics hardware
is better suited for the 3D display features of AutoCAD 2007 and later releases,
and non-certified graphics hardware may not support these features or may
cause problems during use.
Graphics card information for the current system is available in the
Performance Tuner Log, which you can view by clicking the View Tune Log
button in this dialog box.
