■ 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.
