Software Installation
3.1 Windows 95/98
3.1.1 Installing WinFast 3D S325 Drivers and DirectX™ 6 forWindows 95/98
During the booting of Win95/98 after having inserted the WinFast 3D S325 card into AGP slot, the new
installed hardware will be detected and the “Update Device Driver Wizard” window will appear on the
screen. At this point, if your machine has updated version of “VGARTD” software installed then you can
use the “nv4agp.inf” file in the accompany CD to install the driver, otherwise lets Windows install the
“Standard PCI GraphicsAdapter (VGA)” driver which Windows found.
When Standard VGA driver installation is complete, Windows will prompt you to restart your Windows.
Click “NO” to response the prompt and follows the steps described below for continuing installation:
Note: The WinFast 3D S325 package contains the “WinFast Software Pack CD”
,
Please read the “Readme.txt

Step 1 Insert the WinFast Software Pack CD into the CD-ROM drive.
Step 2 The “Autorun” will be executed immediately and a “WinFast 3D S320/S320II/S320V/S325
Installation Program” dialog with four selectable buttons will be shown on the screen. Click
the”Win9x” button to install the driver for Win95/98 automatically.
Step 3 When finishing the driver installation follow the screen direction “Restart” Windows 95/98.
Step 4 Eject the CD-ROM and load WinFast Software Pack CD again. Click the “DirectX™ 6”
button to install the DirectX™ 6 to your machine for better 3D performance.
Note: If the autorun function is not enabled on your machine. Please find the “Install.exe” file in the root
directory of CD and double click it to install the software automatically.

When drivers were installed properly, right click on
Win95/98 desktop wallpaper area and select
“Properties” item. A window with a title name
“Display Properties” will appear on your screen as
shown on the right.
NOTE: Please enable the Monitor Protective
Setting by click the check box to protect
your monitor. This sets the range of

Display Area you can select according to
your specific monitor manufacturer.
Click the “Speed Runner” button, another sheet of

You can use Speed Runner function, according to
your system environment, to adjust clock frequency of
both chip and memory to an optimal value for better
performance.

“Direct3D” Tab
The RIVA TNT2 M64 can automatically generate
mipmaps to increase the efficiency of texture
transfers across the bus and provide higher
application performance.
However, some applications may not display
correctly when auto-generated mipmaps are
enabled. To correct any problems, reduce the
number of automatically generated mipmap levels
until the images are properly displayed. Reducing
the number of mipmap levels can often eliminate
texture misalignment or "seaming" (at the expense
of some performance).
Allows you to select the auto-mipmapping method
used by the RIVA TNT2 M64.
You can select either the bilinear or trilinear
mipmapping method, whereby the bilinear method
generally provides better performance, while the
trilinear method generally produces a higher quality
image.

Allows you to adjust the LOD (Level of Detail) bias
for mi
p
ma
p
s.
A lower bias will provide better image quality, while a
higher bias will increase application performance. You
can choose from five preset bias values, varying from
"Best Image Quality" to "Best Performance"
This option allows for dithering of trilinear mpmaps.
Allowing mipmap dithering will provide increased
application performance at the expense of some image
quality. In some cases, a loss of image quality may not
be noticeable, so you may wish to take advantage of
the extra performance gained by enabling this feature.
These options allow you to control the anti-aliasing
features of the drivers
Anti-aliasing is a method used to smooth edges of 3D
objects to eliminate a jagged appearance. Note that
enabling anti-aliasing will not automatically cause all
Direct3D™ programs to render anti-aliased images.
Anti-aliasing must be supported by the application in
order for it to work properly.
Properties

Allows you to select the anti-aliasing sampling
method.
You can adjust the settings to values which range
from providing the fastest application performance
to rendering the highest quality image.
Lets you save the current settings as a custom
"tweak". Saved settings will then be added to the
adjacent list.
Once you have found the optimal settings for a
particular Direct3D™ application, saving the
settings as a custom tweak allows you to quickly
configure Direct3D™ before starting the program
and eliminates the need to set each of the options
individually.
Displays a dialog which allows you to customize
additional Direct3D™ settings for the RIVA TNT2
M64 as shown on next page.

This option is used to turn fog table emulation on or
off.
Direct3D™ specifies that a display adapter capable of
D3D hardware acceleration should be able to
implement either vertex fog or table fog. Some games
do not correctly query the D3D hardware capabilities
and expect table fog support. Choosing this option
will ensure that such games will run properly on the
RIVA TNT2 M64.
This option allows you to disable the DirectX™ 6
features of the drivers.
Some games written for earlier versions of DirectX™
may not run properly with DirectX™ 6 installed and
the DirectX™ 6 support enabled in the drivers.
Selecting this option forces the drivers to run in
DirectX™ 5 compatibility mode so that older games
will run correctly.
Use this option if you wish to run certain older games
that do not start or do not run as they should.

This option changes the hardware texture addressing scheme for
texels (texture elements).
Changing these values will change where texel origin is defined. The
default values conform to the Direct3D™ specifications. Some
software may expect the texel origin to be defined elsewhere. The
image quality of such applications will improve if the texel origin is
redefined. Use the slider control to adjust the texel origin anywhere
between the upper left corner and the center of the texel.
Allows you to specify the maximum size of the PCI texture heap.
Increasing this value on PCI systems with sufficient memory may
significantly improve the performance of some Direct3D™
applications.
For performance reasons, this utility will not allow you to set the
value to more than one half of the available system memory as
reported by Windows.
This option is not available on display adapters which use the AGP
bus.
This option allows you to limit the number of frames the CPU can prepare before they are processed by the RIVA
TNT2 M64 (when VSYNC is disabled).
In some cases, the higher the number of pre-rendered frames allowed, the greater the "input lag" may be in response
to devices such as joysticks, gamepads or keyboards.
Reduce this value if you experience a noticeable delay in response to the input devices connected to your computer
while playing games.

Allows you to adjust the image quality of textures displayed in
OpenGL™ applications.
Optimize for best image quality renders textures with the
highest image quality available for the best appearance.
Optimize for best performance renders textures with
reduced image quality to improve application performance.
Blend uses a combination of the above two features. This is
the default value.
This option turns on page flipping for full-screen OpenGL™
applications, which may improve their performance. If
disabled, OpenGL™ will use a bit block transfer to flip from
the back buffer to the front buffer.
This option forces the driver to wait on VBlank after a page
flip
This allows for frame rates higher than the refresh rate of your
monitor, but may produce visual artifacts and tearing resulting
in reduced image quality.
A list of the custom settings (or "tweaks") you have saved.
Selecting an item from the list will activate the setting. To
apply the setting, choose the "OK" or "Apply" button.
