Questions on 3d settings

Hey all,

I just recently put a BFG 8800 GTS 640 mb card in my system.
I am running the 97.94 Forceware drivers supplied by BFG.
My current system:
EVGA 680i mb
Intel Core2 Duo E6600 - running at 3.0 ghz
2gb Corsair Extreme PC8500 ddr2 ram

It has been quite some time, since I have owned an Nvidia card, having used
ATI for the last few years, and am curious about some of the 3d settings in
Nvidia control panel.

1: Antialiasing - I normally run at 4x, what is gamma correction, and
transparency? Should these be set to off or on normally, and what impact
might they have on performance? What would be the benefit, of having these
two set to on, versus off, if any?
Also, I see there is like an 8xQ, and a 16xq - what is the difference
between the q, and say just an 8x or 16x?

2: Triple Buffering - mine by default, is set to off - is this preferable,
to having it set to on?

3: Texture Filtering - negative lod bias - mine by default is set to "
clamp", the other option is " allow" - what does this do?

I'll stop there for now, some of these may be stupid questions I am sure...

Thanks for any tips,

Certain AA sampling and blending patterns cause the screen brightness to
drop a little. ATi's AA implementation included gamma correction by default
since the Radeon 9x00 days. nVidia gives you the option to turn it on or
off. Experiment to see what you like better.

Simply, the alpha textures receive AA as well, similar to ATi's Adaptive AA.
Transparency supersampling AA is the equivalent of Adaptive AA in "quality"
mode. For details, go he

is correct...

As far as the user is concerned, just know that "Q" modes provide better
quality, but are slower.

Gamma correction:

Gamma is the function that relates the signal to light intensity or light to
signal intensity. For a monitor a gamma of 1 is a linear increase in
brightness with equal steps in brightness from dark to light. A gamma of
less than one gives a image with 'stretched' blacks and 'compressed' whites
(more detail in the darkest part of an image a gamma of more than one
gives an image with compressed blacks and stretched whites (more detail in
the lightest part of an image.) A monitor has three colors of pixels, so
there is a gamma for each color; red, green, and blue. If these three
gammas are not equal, the image will change tint as the brightness varies
and only 100% white and complete black will be correct; grays will be
tinted. When you have trouble making out detail in the darkest portion of
images in a game, then reduce the gamma. For other applications (editing a
photo, for example) you should either use the preset gamma provided for the
particular monitor or use a gamma/contrast/brightness setting applet.

Good info, thanks for that Phil.
