map levels computed by trilinear texturing are available
for use by the Direct3D application.
High quality images will be sharper and more aliased
and will result from the use of a higher number of MIP
map levels. Blurrier images result from using a smaller
number of intermediary MIP map levels. Because less
texture data is used, higher performance is associated
with fewer MIP map levels.
Setting options include:
Auto (default) – Select Auto to let S3 Graphics
software provide optimized control of adjustments for
Level of Detail bias.
0 (Quality) – Select 0 (Quality) to use the highest
available visual quality, using the maximum Level of
Detail bias. This number tells S3 Graphics software
to use the highest number of MIP map levels
possible. This setting will produce the greatest level
of visual quality and detail, but will often have a
significant impact on rendering speed, as much
texture data is processed.
1, 2, 3, 4, 5, 6, 7…– Select any intermediate level to
achieve your optimal balance between quality and
performance.
8 (Performance) – Select 8 (Performance) to tell S3
Graphics software to use the smallest number of MIP
map levels available. This setting will produce higher
speed performance at the expense of visual quality.
Max depth buffer
size
Use this setting to control the maximum precision
available for the Depth Buffer (Z buffer). Visual quality
increases with the greater precision available when
using higher bit buffers. There may be a slight
corresponding decrease in rendering speed.
Setting options include:
By App (default) – Select By App if you want S3
Graphics software to provide the depth buffer size
requested by the application. This is the default.
16-bit – Select 16 for force a 16 bit depth buffer.
Applications may request a 16 bit depth buffer. This
depth will provide the fastest rendering speed.
Because this is the least precise format, it has the
potential for decreased visual quality, especially by
creating surface artifacts in distant objects.
24-bit – Select 24 to force a 24 bit depth buffer,
which would be a buffer with single precision floating
