with AutoCAD, check with the software vendor to see if it supports hardware
acceleration and if not, disable hardware acceleration prior to starting the remote
access software or use the /NOHARDWARE command line switch to start AutoCAD
in Software mode.
General Settings
Sets performance-related options that are not hardware dependent.
Discard Back Faces
When selected, the back faces of objects are not drawn.
Smooth Faces by Default
When selected, the facets in a polyface mesh object are made smooth when
displayed in the viewport and in a rendering. This is useful when using objects
that were imported through 3DSIN or when using PFACE objects. Note that
when you select this option, all objects in the drawing are made smooth. If
you dont want all objects to be smooth, recreate the model using a different
object type.
Transparency Quality
Adjusts the transparency quality used when viewing or rendering a model.
The transparency quality used is dependent on if software or hardware
acceleration are used, or if a model is being rendered. The default quality is
Medium.
Software acceleration
Low quality produces a screen-door effect to achieve transparency without
sacrificing speed.
Medium quality uses a combination of the screen-door effect and alpha
blending.
High quality uses simple alpha blending, which can cause graphical artifacts
to appear based on the current draw order.
Hardware acceleration
Low quality uses simple alpha blending, which can cause graphical artifacts
to appear based on the current draw order.
Medium quality uses a two-pass algorithm to draw all opaque objects,
followed by all transparent objects. The transparent objects are drawn
using simple alpha blending, which can cause graphical artifacts to appear
