■ Smooth display. Controls the status of the full screen anti-aliasing effect.
This option removes the jagged effect on the display of diagonal line and
curved edges.
■ Advanced material effects. Controls the status of the advanced materials
effect on screen.
■ Gooch hardware shader. Enables the use of Gooch shading. With this
option on the details of a 3D object are shown by softening the contrast
between lighted areas and shadowed areas by using warm and cool colors
as a substitute to light and dark colors.
■ Per-pixel lighting. Enables the computation of colors for individual pixels.
With this option on the 3D objects and lighting effects appear smoother
in the viewport.
■ Full shadow display. Enables shadows to be displayed in the viewport.
NOTE Enhanced 3D performance effect must be turned on.
■ Texture compression. Enables the use of texture compression to reduce
the amount of video memory required to open and display a drawing that
contains materials with images or has attached images.
NOTE With this option turned on, the time it takes to load the images might
increase the first time that they are accessed, and there is a reduction in the
quality of the images when they are displayed in the viewport or plotted.
■ Enhanced 2D precision. Enables the Enhanced 2D precision effect. With
this option turned on, the precision artifacts that can be seen at extreme
zoom levels are removed.
NOTE This option is only available if you are working on a Windows Vista
platform. Turn on this option only if you experience problems with precision
because it will decrease the graphics card performance.
Emulate Unsupported Hardware Effects in Software When Plotting
Controls whether software emulation is used for unsupported hardware effects
when plotting shaded viewports with shadows and other effects that are not
supported by your graphics card.
WARNING It is recommended that you not use any type of remote access
application, such as NetMeeting, Remote Desktop, or any windows emulating
software in conjunction with hardware acceleration. Most remote access
applications do not support hardware acceleration, and as a result, can cause
general display failure and instability. Prior to using a remote access application
