4. Check to see if the card is firmly seated in its AGP bus
expansion slot. It should not be making contact with any
other cards in the system.
Note
: Turn the system off before adjusting the card.
8.2 Frequently Asked Questions (FAQ)
Q1
Why do we need 3D graphics capability in our PC?
Answer
3D technology is becoming increasingly important (and
common) not only in games, but also in other applications such
as VRML, which allows 3D scene descriptions in Web
applications. 3D technology is used for image editing, modeling,
and an increasing number of in home and business applications.
In games, as well as other applications, 3D acceleration not only
allows better visual qualities and more realistic scenery
attributes than software alone, but it also allows a higher frame
rate, which translates into a more interactive experience for the
end user.
Q2
What does “Rendering Engine” mean?
Answer
“Rendering Engine” generically applies to the part of the
graphics engine that draws 3D primitives, usually triangles. In
most implementations, the rendering engine is responsible for
interpolation of edges and “filling in” the triangle.
Q3
What does the set-up engine do in a graphics controller?
Answer
A set-up engine allows drivers to pass triangles in the form of
raw vertex information; whereas, most common designs force
triangles to be pre-processed for the rendering engine in terms
of delta values for edges, color, and texture.
Q4
Why does a 3D graphics chip need to have both a rendering
engine and a setup engine?
Answer
Any “3D application”, a game, VRML, or modeling package, can
benefit from 3D rendering. This is especially true of applications
that use texturing extensively, because texturing and texture
filtering are very intensive operations at the pixel level in terms
of CPU operations and demands for memory bandwidth.
Without a set-up engine in a graphics controller, the CPU has to
calculate the delta values for edges, color, and textures; the
drivers need to handle ten (10) times more extensive data. This
