۳D Graphics System Configuration Settings

Two settings for your graphics system configuration will affect the preview. To access
these settings, enter ۳dconfig, and click Manual Tune to display the Manual Performance Tuning dialog box. For more
information, see Performance Tuning.

• Texture Compression. When Texture Compression is turned on, there is a reduction in the quality of the
  images in the drawing when they are previewed. Texture Compression does not affect
  viewports that are rendered. To identify whether Texture Compression is turned on,
  look at the Hardware Effects List in the Manual Performance Tuning dialog box.
• Hardware Acceleration. When hardware acceleration is turned on or off, but does not support shadows, it
  is possible to preview a drawing that contains shaded viewports with unsupported hardware
  effects by the graphics card through software emulation. To enable the software emulation
  of hardware effects that are not supported by your graphics card, in the Manual Performance
  Tuning dialog box, click Emulate unsupported hardware effects in software when plotting.
  The unsupported effects will not appear in the viewport in real-time, but will appear
  when previewing the drawing.
