Enable buffer region extension:

can increase
performance in 3D modeling
applications that support this
extension.
Allow the dual planes extension
to use local video memory:
Allows the use of local video
memory
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.
Use fast linear-mipmap-linear filtering: 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.
Disable support for enhanced CPU instruction sets: 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.
Force 16 bit Depth Buffer: This 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 other operations at
the cost of less precision in the depth buffer.
Default color depth for texture: 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,
