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 your NVidia graphics processor.


This option allows you to disable the newer DirectX features of the drivers.

Some games written for earlier versions of DirectX may not run properly with DirectX versions 6 or 7 installed and their 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.


Forces the hardware to automatically adjust the depth of its Z-buffer to the depth that the application requests.

Normally, you will want to keep this option enabled, unless your work absolutely requires a specific Z-buffer depth. If this option is disabled, any application whose working Z-buffer depth does not match that of the current hardware configuration will not run.


Enables an alternate technique for depth buffering.

This lets the hardware use a different mechanism for depth buffering in 16 bit applications. Enabling this setting can produce higher quality rendering of 3D images.


Enables the NVidia logo in Direct3D.

Enabling this setting will display the NVidia logo in the lower corner of the screen while running Direct3D applications.


Your NVidia graphics processor 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 graphics processor.

You can select either the bilinear or the 8-tap anisotropic mipmapping method, whereby the bilinear method generally provides better performance, while the anisotropic method generally produces a higher quality image.


Allows you to adjust the LOD (Level of Detail) bias for mipmaps.

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".


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.


Lets you save the current settings (including those set in the "More Direct3D" dialog) 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 game, saving the settings as a custom tweak allows you to quickly configure Direct3D before starting the game and eliminates the need to set each of the options individually.


Deletes the custom setting currently selected in the list.


Restores all settings to their default values.


Displays a dialog which allows you to customize additional Direct3D settings.


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.


This allows the graphics processor to utilize up to the specified amount of system memory for texture storage (in addition to the memory installed on the display adapter itself).

Note:	The maximum amount of system memory that can be reserved for texture storage is calculated based on the amount of physical RAM installed in your computer. The more system RAM, the higher the value you will be able to set.

This setting applies only to PCI display adapters (or AGP display adapters running in PCI compatibility mode).


Select this option to disable vertical sync.

Allows the image to be immediately rendered to the screen without waiting to be synchronized to the vertical retrace of the monitor. 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.


This option allows you to determine the amount of antialiasing used in a particular D3D application.

Antialiasing is a technique used to minimize the "stairstep" effect sometimes seen along the edges of 3D objects. Your selection can range from turning antialiasing completely off to selecting the maximum amount possible for a particular application.


Use this option to force antialiasing in applications that do not directly support it.

Note that some applications which do not explicitly support antialiasing may not display properly or may render irregular images. Use this option with care. Turn this option off if you experience display problems with a game or application that does not support antialiasing.


This option allows you to limit the number of frames the CPU can prepare before they are processed by the graphics chip when vertical sync 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 the drivers to use the OpenGL extension GL_KTX_buffer_region.

This can increase application performance in 3D modeling applications that support this extension.


Allows the use of local video memory when the GL_KTX_buffer_region extension is enabled.

However, if there are less than 8 MB of local video memory available, dual planes extension support will not be enabled.

This setting has no effect if the "Enable buffer region extension" option above is disabled.


Allowing fast linear-mipmap-linear filtering will provide increased application performance at the expense of some image quality.

In many 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.


This option allows OpenGL to use anisotropic filtering for improved image quality.


Select this option to disable driver support for enhanced instructions used by certain CPUs.

Some CPUs support additional 3D instructions that complement your NVidia graphics processor and improve performance in 3D games or applications. This option allows you to disable support for these additional 3D instructions in the drivers. This can be useful for performance comparisons or for troubleshooting.


These options control full scene antialiasing for the OpenGL driver. Antialiasing is a technique used to smooth the edges of objects in a scene to reduce the jagged "stairstep" effect sometimes seen. The 1.5 x 1.5 method offers antialiasing with the best performance, while the 2 x 2 method provides the highest image quality.


This option determines whether textures of a specific color depth should be used by default in OpenGL applications.

Use desktop color depth will always use textures of the color depth at which your Windows desktop is currently running.

The Always use 16 bpp and Always use 32 bpp options will force the use of textures of the specified color depth, regardless of your desktop settings.


This option determines the buffer flipping mode for full-screen OpenGL applications.

You can select from the block transfer method, the page flip method or auto-select. Auto-select allows the driver to determine the best method based on your hardware configuration.


This option lets you specify how vertical sync is handled in OpenGL.

Always off will always disable vertical sync in all OpenGL applications.

Off by default will keep vertical sync disabled, unless an application specifically requests that it be enabled.

On by default will keep vertical sync enabled, unless an application specifically requests that it be disabled.


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 OpenGL application, saving the settings as a custom tweak allows you to quickly configure OpenGL before starting the program and eliminates the need to set each of the options individually.


The slider controls allow you to adjust the brightness, contrast or gamma values for the selected color channel.

The color correction controls help you to compensate for variations in luminance between a source image and its output on a display device. This is useful when working with image processing applications to help provide more accurate color reproduction of images (such as photographs) when they are displayed on your monitor.

Also, many 3D-accelerated games may appear too dark to play. Increasing the brightness and/or gamma value equally across all channels will make these games appear brighter, making them more playable.


Allows you to select the color channel controlled by the sliders. You can adjust the red, green or blue channels individually or all three channels at once.


Digital Vibrance gives you more control over color separation and intensity, resulting in brighter cleaner images in all of your applications.


A graphical representation of the color curve. This curve will change in real time as you adjust the contrast, brightness or gamma.


Selecting this option will automatically restore the color adjustments you have made here when Windows is restarted.

Note:	If your computer is running on a network, the color will be adjusted after you have logged on to Windows

Lets you save the current color settings as a custom setting. Saved settings will then be added to the adjacent list.


Deletes the custom color setting currently selected in the list.


Restores all color values to the hardware factory settings.


Allows you to select your monitor timing mode:

Auto-Detect allows Windows to receive the proper timing information directly from the monitor itself. This is the default setting. Note that some older monitors may not support this feature.

General Timing Formula or GTF is a standard used by most newer hardware.

Discrete Monitor Timings or DMT is an older standard still in use on some hardware. Enable this option if your hardware requires DMT.

Note:	If your country is not in the list, you should select the country closest to your location.


Makes the selected format the power-up default.

When starting up the computer with only a TV attached to the display adapter, this option ensures that all screen messages displayed during the boot process will be output in the proper format supported by your television.


Lets you specify the type of output signal sent to the TV.

If you have the proper connector cable, S-Video out will generally provide a higher quality output than Composite video out. If you are not sure which type of signal you should specify, choose the Auto-select setting.


Use the arrow buttons to adjust the position of the desktop on the TV.

Note:	If the TV picture becomes scrambled or goes blank due to overadjustment, simply wait 10 seconds. The picture will automatically return to its default position. Then you can begin your adjustments again. Once you have positioned the desktop where you want it, you must press the "OK" or "Apply" button to save the settings before the 10 second interval has elapsed.


Resets the desktop to its default position on the TV for the current resolution.


Use these controls to adjust the brightness and saturation of the TV image.

Note:	You can bypass the automatic clock setting at startup by holding down the <Ctrl> key while Windows is starting. If your computer is connected to a network, hold down the <Ctrl> key immediately after you have logged on to Windows.


Resets all clock adjustment capabilities and forces a redetection of the graphics hardware before the controls can be reenabled.

It is recommended that you perform a reset any time you flash the BIOS of your display adapter with an updated BIOS image.


Allows you to select one of four TwinView modes:

Standard – Selects the standard, single display mode. Use this mode if you have only one display device attached to your Nvidia graphics adapter

Clone – This mode outputs an exact copy of the primary display on the secondary device.

Horizontal Span – This mode allows you to extend the Windows desktop across two display devices horizontally.  In this mode the the two displays combine to form one large spanned display surface.

Vertical Span – This mode allows you to extend the Windows desktop across two display devices vertically.  In this mode the the two displays combine to form one large spanned display surface.


When running in clone mode, this option allows you to run your primary display device at a higher desktop resolution than that of the secondary device. If the physical resolution of the secondary device is lower than that of the primary, the desktop on the secondary device will automatically pan as the mouse touches the borders of the screen.


Turns off the automatic panning feature on the secondary device if the "Allow virtual desktop on clone device" option is selected. This lets you effectively "freeze" the virtual desktop at a certain position. This is useful for presentations or fine detail work in applications.

Shows the type of monitor you are using with the selected video adapter.


Click to display device and driver properties for this monitor.


Lists the refresh rates available for this monitor.  A higher refresh frequency reduces flicker on you screen.


Specifies whether the list under Refresh Frequency will include modes that are not supported by your monitor.  Choosing a mode that is inappropriate for your monitor may cause severe display problems and could damage your hardware.  You must be logged on as a member of the Administrator's group in order to view unsupported modes.


The option forces the OpenGL driver to use a 16 bit depth buffer regardless of the pixel format chosen by the application.

 This improves the performance of depth buffer clears and operations at the cost of less precision in the depth buffer.


When enabled, OpenGL will use the Windows2000 Advanced Multi-Monitor feature.


Use this option to select which display contains the top left corner of the desktop.  The most obvious effect of this option is that it swaps the positions of the monitor images.

This key-combination moves all application windows onto the display where the mouse pointer is located.


When you have multiple application desktops active, this key-combination switches from one desktop to another. Repeatedly using this combination will cycle through the list of active application desktops.


The Global Settings page contains options that are global to Desktop Display Manager and its handling of all applications.


Choosing to maximize an application to "the entire desktop" means that maximizing it will fill the entire desktop, even when the latter spans multiple monitors.

Choosing to maximize an application to "its current screen" means that by default, maximizing an application will cause it to fill only the screen that it originally occupied.


Enabling this feature will insert an "NVIDIA Desktop Manager" submenu into the system menus of all top-level application windows. This submenu allows quick and easy access to all Application Management functions, without the need to open the Desktop Display Manager control panel.

An application window's system menu is accessed by right-clicking on the window caption (title bar), or by clicking on the small application icon at the left end of the window caption.


Selecting this option allows the Desktop Display Manager to prevent top-level pop-up windows from spanning or breaking across two (or more) monitors, by repositioning the popup to fit on one screen.


Choose this option to always center system-wide pop-up windows on the screen of your choice.


Select the monitor on which you wish pop-up windows to be centered. This field is only available when you check the "Center system-wide pop-ups on screen number" button.


This option causes system-wide pop-up windows (that span multiple monitors) to be centered on the display that contains the mouse cursor, since that is most likely to be the display that you are watching.


This option keeps application pop-up windows on the same screen as the application window that generated them. If a pop-up "strays" onto another monitor, the Desktop Display Manager will move it to fit on the application window's display.
