Display Properties 4-7
Direct3D Settings:
 Mipmap detail level: 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”.
 Maximum system memory for
PCI mode textures: 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).
 Enable fog table emulation: 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.
 Custom Direct3D settings: 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.
