Build 0.48 Release Notes This release includes additional support for the following game titles and demos: "Unreal" from Epic Megagames - D3D version. This driver fixes the following reported problems: Rainbow colors on some textures Controller time-lag issues (when registry settings noted below are used) Texture dropouts due to W-buffering problems Missing textures "Descent3" demo from Outrage Entertainment/Parallax Software "Rogue Squadron" from LucasArts This driver fixes the following problems for the these two applications: Texture dropouts and other visual artifacts caused by W-buffering issues Setting the Recommended Registry Settings for "Unreal" Run the REGEDIT program (START menu, choose "RUN", type REGEDIT and press RETURN) Click the plus sign next to "HKEY_LOCAL_MACHINE" to view the sub-categories) Click the plus sign next to "Software" to view the sub-categories) Click the plus sign next to "Microsoft" to view the sub-categories; (NOTE you may need to scroll within the window to see "Microsoft") Look for "UnrealD3D" under "Microsoft" (sub-categories should be listed alphabetically) If "UnrealD3D" does NOT exist, add it by right-clicking on "Microsoft" and choosing New|Key from the pop-up menus. Re-name the new key "UnrealD3D". You should be able to type a new name when you create the new Key, but you can also right-click the Key name to rename it. Right-click on "UnrealD3D" and choose New|DWORD from the pop-up menu. Rename the new DWORD to "DoFlip". Double-click on "DoFlip" and set the value to 1. Make sure that "hexadecimal" is checked rather than "decimal." Exit the Registry editor, your changes are automatically saved. 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.) System Requirements to use the NVIDIA Reference Drivers Win95 System requirements: - OSR2 for full AGP functionality (which includes Microsoft's OPENGL32.DLL) - Microsoft's OPENGL32.DLL - Microsoft’s Dx5 or greater - 2MB disk space Win98 System requirements - Microsoft’s Dx5 or greater - 2MB disk space WinNT System requirements: - Service Pack 3 - 2MB disk space Downloading the NVIDIA Reference Drivers: To download the Build 0.48 Reference Drivers begin by clicking on the correct driver version for your system. select WIN9x048ag.ZIP to install drivers on Win95 AGP systems select WIN9x048p.ZIP to install drivers on Win95/98 PCI systems select NT4048.ZIP to install drivers on WinNT systems This will download the compressed driver to your system. Save it in a temporary directory on your system disk. example: c:\RIVATNT The following sections will help you install our latest Win95/98 or WinNT display drivers which include the OpenGL ICD driver. Win95 Installation Information: Before installing the new drivers it is recommended that you have a copy of your current drivers, usually supplied with your board. If not previously installed, you will need to install these on your system first: 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/msdownload/default.htm The final version of Dx6 can be obtained 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 When you are ready: 4. Unzip the ZIP file you downloaded to an empty folder (such as C:\RIVATNT). 5. Close all programs 6. Install the driver using the Display Properties dialog box: Click Start, then Settings, then Control Panel. Start the "Display" applet program. Select the "Settings" tab Push the "Change Display Type" button (or the “Advanced Properties” button). Push the "Change" button in the "Adapter Type" area. The "Select Device" dialog box will appear, push the “Have Disk” button. Specify the path to the new unzipped driver by pressing “Browse…” After selecting the correct path press “OK”. Click “OK” twice to install the new drivers. Close down the open windows. 7. After successfully installing the reference drivers, you will need to restart the operating system for the new drivers to take effect. Windows 98 Installation Information 1.Unzip WIN9xxxx.ZIP to an empty folder (such as C:\RIVATNT). 2. Close all programs 3.

The system should find a .inf file in the location you specify. Press “OK”. Click “OK”, then “Next”, then “Finish” 4. After successfully installing the reference drivers, you will need to restart the operating system for the new drivers to take effect. WinNT Installation Information: Before installing the new drivers it is recommended that you have a copy of your current drivers, usually supplied with your board. If not previously installed, you will need to install this on your system first: 1. Install Microsoft's Service Pack 3 for Windows NT 4.0 on your system. You can obtain this by browsing for "Support Drivers, Patches and Service Packs" \ "Windows NT Service Packs" from: http://www.microsoft.com/msdownload/default.htm When you are ready: 2. Unzip NT.ZIP to an empty folder. 3. Close all programs 4. Choose NT's Start\Settings\Control Panel\Display\Settings\Display Type\Change\Have Disk\Browse. 5. Locate the folder with the unzipped reference drivers...Display should list NVIDIA RIVA TNT 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.
