How to remove display utilities or control panels for your display card:

To remove the display utilities or control panels for a display card you are currently using, you must first locate and identify them. There are four main places where you should look for these items:

1. The first and most important place to look is in the user’s guide, installation instructions, or owner’s manual for the card you are about to remove. Any programs that would have been added to your system when you installed the card should be described in the documentation for that card. There may also be specific instructions for uninstalling the card’s software from your system. If so, you should use those instructions to remove the card’s software.
2. Many programs of this type add an item to the "Programs" menu on your Windows "Start" menu. Such an item may be listed by the name of the display card it is associated with, or by the name of the company that manufactured the card. Display utilities and control panels like this are often given their own specific names, like the "3dfx Tools" software for your new Velocity 100 card. If you find such an entry, look to see if there is also an "Uninstall" option listed there. If you find one, then that is probably what you should use to remove the software from your system.
3. The Windows Control Panel probably contains the actual program icons for any display utilities or control panels that may have been installed on your system with the old card. This may help you to identify the program you wish to remove, although it probably will not give you direct access to a method for removing it. However, the "Add/Remove Programs" item in the Windows Control Panel can probably remove the software for you once you know what software to remove.
4. The Windows "StartUp" folder may contain a shortcut to the display utility or control panel for the old card. If so, you can simply delete the shortcut from the "StartUp" folder to disable the program, but that will not remove the software from your system. You may also want to use the "Add/Remove Programs" item in the Windows Control Panel to actually remove the software from your system.

There are several methods available for opening the Display Properties dialog box:

• Click your right mouse button while the cursor is on any empty portion of your Windows desktop, not on any icon or in any open program window. Select "Properties" from the menu that appears.

• Click on the "Start" button, select "Settings", then select "Control Panel". Next, double-click on the "Display" icon.

The Control Panel typically contains the standard arrangement of icons shown in the diagram below, as well as any additional icons for programs, utilities, or control panels that may have been installed by other programs or devices. Please notice that the icons in your Control Panel may be different from the ones shown here, depending on the Windows options and other software you have installed. Also, the "Display" item shown opens the standard Windows "Display Properties" dialog box and you should not try to remove it from the Windows Control Panel.

 The typical arrangement of icons in the Windows 98 Control Panel

Examine the icons in your Control Panel for any display utilities or controls that were installed along with the card you are about to remove from your computer. When you remove or uninstall the software for the current display card, you may be prompted to restart your system. Please do so before you continue.

One of the items shown in the Windows Control Panel is called "Add/Remove Programs". Double-click on the icon to open the "Add/Remove Programs" dialog box. Scroll through the list of programs in that dialog box to identify any display utilities like 3dfx Tools. Select the program you want to remove and click on the "Add/Remove..." button. Follow the on-screen instructions to complete the process.

When you have opened the "Display Properties" dialog box, select the "Settings" tab and then click on the "Advanced…" button to open the 3dfx Properties dialog box.

There will be some new tabs in this dialog box, added by the 3dfx Tools software for your Velocity 100 card:

• 3dfx Info
• 3dfx Tweaks

There will also be a new 3dfx Tools Control Panel icon in your Windows Control Panel.

Select the "3dfx Info" tab to open the "3dfx Info" page, shown here…

The "3dfx Info" page of the Velocity 100 Properties dialog box

NOTE: The "x.x.x.xx" shown in the above example would be replaced with the actual version number of your 3dfx Tools software.

Click on the small "+" to the left of an entry to view the details for that item. The information available for your Velocity 100 card includes:

• Product (name)
• Hardware Version
• Manufacturer
• Total Video Memory
• GFX (graphics chip) Clock Speed
• Memory Clock Speed

The version of the 3dfx Tools software that you are currently using is also shown here. The last two items listed give you access to information about the current and previous display adapters and monitors you have used with your system.

Select the "3dfx Tweaks" tab to open the "3dfx Tweaks" page, shown here…

The "3dfx Tweaks" page of the Velocity 100 Properties dialog box

NOTE: Changing the settings on the "3dfx Tweaks" page could affect the visual quality or display performance of your Velocity 100 card with some software. You should only make changes to these settings if you are sure they are necessary for the proper functioning of the software you are using.

Gamma Settings

The controls in the "Gamma Settings" group allow you to increase or decrease the color brightness levels of your display. If your display seems too dark or too bright, move the Gamma slider controls to the left to decrease the Gamma levels or to the right to increase the Gamma levels. If you need to adjust the relative color levels for your display, then remove the check from the "Lock Gamma" slider controls to move the Gamma slider controls for each color separately (R = Red, G = Green, B = Blue). The default Gamma Setting is 1.00 for each color.

Selection

The three options in the "Selection" group allow you to choose which set of the Velocity 100 card's features you want to change. When the "Desktop" option is selected, you can change the Velocity 100 card's Gamma Settings for your Windows desktop environment itself. Please note that this option only affects the non-3D functions of Microsoft's DirectX.

Direct3D

This option allows you to change the Velocity 100 card's Gamma Settings for your Direct3D applications, and to change the video overlay option in the "D3D / DirectDraw" section.

Glide / OpenGL

Select this option to change the Gamma Settings for your Glide and OpenGL applications, and to change any of the options in the "Glide / OpenGL" group of controls:

• Disable the splash screen - Place a check in this checkbox to disable the Glide splash screen.

• Force mipmap dithering - Place a check in this checkbox to enable texture mipmap dithering. This may improve the visual quality of some applications, but it may also decrease the rendering performance of your Velocity 100 card.

• Limit texture memory to 2MB - Place a check in this checkbox to reserve two megabytes of texture memory for the texture mapping unit in a Glide application. Some Glide games may not work properly unless this option is selected.

• Force triple buffering - Place a check in this checkbox to enable triple buffering if the Glide application has enough frame buffer memory available to support it. This may improve the rendering performance of your Velocity 100 card in some Glide applications, but all Glide applications are not compatible with triple buffering and may produce unusual display "artifacts" if this option is selected.

Reset to Previous

Click this button to undo any changes you have made to the options for the current selection (Desktop, Direct3D, or Glide / OpenGL).

Factory Defaults

Click this button to restore the original factory default values for the currently selected option.
