Chapter 1
Installing the HP Visualize fx+ Graphics Card
Description
This option can improve the OpenGL performance
if an OpenGL application is using a large number
of calls to glRasterPos, g1Bitmap, glDrawPixels,
or glPushAttrib. This option can reduce
performance for applications that are not heavy
users of one of these calls, so it should only be
used if the appropriate conditions exist.
When this option is set, texture mapping becomes
NOOP (NO OPeration). All texture commands
sent by an application are ignored. If the texture
module is not installed, setting this option can be
useful to simulate the performance with the texture
module installed. However, visual results are poor,
and actual hardware acceleration with the texture
module will be slightly slower than this simulated
performance.
When this option is set, the most recently used
texture is replaced when texture memory is full.
This is most useful when many textures are used
sequentially, because it minimizes the number of
textures that are downloaded.
Enabling this feature optimizes lighting
performance at the expense of matrix change
performance. This may improve the performance
of some applications.
Enabling this feature sets OpenGL rendering to be
clipped only to the window boundaries, ignoring
any obscuring windows. This option should
normally not be set since it can cause unexpected
interactions between OpenGL applications. It
should only be set to improve the usage of the no
Redarw on Window Expose option in 3D Studio
MAX and Autocad 2000.
