Known Issues`
`Win95/98 Texture download issues in the game "Unreal" may cause occasional
stuttering. NVIDIA continues to work with Epic to resolve this.`
`Win98-PCI
Users may experience GPFs (general protection faults) when
exiting some OpenGL applications (Chick Berry and 3DMaze screen
saver) if their desktop color depth is set to 8 bits. 3DMaze may
also cause a GPF in 16-bit color.`
`Windows NT 4.0
Fails some WHQL 3D tests, but performance and stability are not compromised.`
`This driver is Build 0.48 of the NVIDIA Reference Driver. This
release of the display driver is to be used with boards based on the RIVA TNT
chip. This release includes drivers for both WinNT4.0 and Win95/98 in either an
AGP or PCI configuration. This Reference Driver is supplied to board
manufacturers for their use in developing fully supported drivers customized for
their specific board configuration. While we expect this driver to operate correctly
on RIVA TNT based boards, we are not able to provide full product support for
other manufacturers products. It is recommended that end users install the
drivers supplied from their board manufacturer to receive full product support.`
`If you were using a Win95 driver from a board manufacturer that also provided a
Control Panel applet, (like Diamond's InControl Tools, STB's Vision, etc.) that
applet will not work correctly with the NVIDIA Reference Driver and can cause
system problems. It should be removed before these new drivers are installed.
(See Installing from non-NVIDIA drivers, below.)`

`1. OSR2 or later for AGP systems (usually pre-installed on AGP systems).
(Optionally, the USB supplement is needed for full AGP functionality. This should
have
been included with your system or motherboard. See your system
manufacturer's web site for this file.)
2. Install Dx5 or greater (the final version of Dx6 is recommended). This is
contained in your board vendor's drivers, on the Microsoft web site, or on a
recent DirectX application. It is recommended you install the latest Service Pack
from Microsoft. You can obtain this by browsing for "Support Drivers, Patches
and Service Packs" \ "Windows 95 Updates" from:

` `http://www.microsoft.com/directx/default.asp``
3. If you have OSR2 or later installed on your system you should already have
Microsoft's OPENGL32.DLL installed on your system. If you do not already have
a version of OPENGL32.DLL in your Windows\System, or you have another
vendor specific OPENGL32.DLL file installed, you need to install Microsoft's`
`OPENGL32.DLL. You can obtain this file and other required files from:
` `ftp://ftp.microsoft.com/Softlib/MSLFILES/opengl95.exe`

6. After NT successfully installs the reference drivers, you will need to restart the
operating system for the new drivers to take effect.`
`Installing from non-NVIDIA drivers:`
`If you are installing the NVIDIA Reference Drivers and presently have non-
NVIDIA supplied drivers installed, it is recommended that you uninstall your
existing driver's Control Panel tools before installing the NVIDIA Reference
Drivers. Our driver does not include the hooks in it to support the tools provided
by other board manufacturers. As a result, their tools will not operate correctly
with the NVIDIA Reference Drivers and could cause system problems if you try
to use them with our drivers. The best way to uninstall drivers is to use an
uninstall utility provided by your board manufacturer. Please contact them for
information on how to uninstall their tools.`
`Uninstalling NVIDIA drivers:`
`If you have a need to do this, first start by uninstalling Control Freak. To do this
use the Add/Remove Programs dialog box:
Click Start, then Settings, then Control Panel.
Start the "Add/Remove Programs" applet program.
Select Control Freak, and click "Add/Remove".
You will now be able to re-install your original driver on the system.`
`General information for all users.`
`About OpenGL:
The NVIDIA Reference Driver Build 0.48 includes our latest
version of the OpenGL ICD for RIVA TNT. This OpenGL ICD is now available for
both Windows 95 and Windows NT. It accelerates rendering of OpenGL
applications when:
- Display is set to 16-bits per pixel or 32-bits per pixel
- Enough video memory exists to support the OpenGL resolution requested
- Microsoft's OPENGL32.DLL is correctly installed`
`Several pre-release versions of the OpenGL ICD have previously been made
available through the Internet. This version should be much more stable, and
should perform better in almost all cases.`
`Microsoft's OpenGL will auto-detect that the RIVA products have hardware-
accelerated OpenGL available, and use that whenever possible. If OpenGL
applications complain about missing required DLL's, or if you are seeing
unusual OpenGL behavior, then it is likely that either you are missing
OPENGL32.DLL, or that an application shipped with a version of
OPENGL32.DLL that is not compatible with the RIVA OpenGL ICD. You should
look in the application's directory for a file called OPENGL32.DLL, and rename it.
The application will then use the OPENGL32.DLL from the Windows\System or
WinNT\System32 directory. You also can obtain the correct OPENGL32.DLL is
by re-installing it from the WindowsNT CD.`
`About Control Freak:`
`Also included in the NVIDIA Reference Drivers is our Control Panel applet,
Control Freak. This applet adds a RIVA tab to the Display Properties Dialog box.
There are several useful controls and setting information here. To learn what
each setting can do, just right click on the setting to get an information box.`
