Registry settings
The only
noteworthy registry setting available relates to the monitor timing method to be
used. Click on Start, Run
type in regedit & hit Enter.
Search for instances of UseGTF (In Windows 9x/Me there should only be 1,
in Windows 2000 there can be several instances of this setting).
Right
click
on this entry when found & select Modify.
Right click on the UseGTF entry &
select Modify. Enter a Value data
of 1 to enable use of the General
Timing Formula (GTF) if you have a fairly new monitor or set it to 0
to use Discreet Monitor Timing (DMT) if have an old monitor
(old being defined as more than 2-3 years). This refers to the ability to change
refresh rate in Windows.
If you have Need For Speed:
Porsche Unleashed & want to run in 32-bit colour (or at least
have the option to) you will need to do the following. Go to [HKEY_LOCAL_MACHINE\Software\Electronic Arts\Need For Speed - Porsche
Unleashed]. Add/Edit
a New String value entitled Thrash
Driver. Right click on the entry & select Modify. Give it a value of dx7
(Previously may have been voodoo2).
Display settings
Click on Start, Settings, Control Panel. Open Display, then select the Settings tab, then the Advanced button. Here you will find tabs for the
different 3dfx Tools. Each of the following sub sections will describe what can
be done in each one.
3dfx Color
Select the 3dfx Color tab. Although you might not think it, if
you adjust your brightness levels correctly you can improve visual quality a
lot. You may be able to reduce the effect of colours/textures being too dark, or
too washed out this way.
Here you can independently adjust the Gamma,
Brightness
& Contrast
settings for Desktop, Direct3D, Glide/OpenGL & Video
Overlay (E.g. Use with playback of movies with
Windows
Media Player
or DVD’s). Personally I have found that setting
Contrast to -5, Brightness to 2
& Gamma to 1.00
to give me the best desktop display. Of course, you can always reference
the Bitmap shown in top right to see the effect of changes you make.
There is an
online calibrator that can help you adjust the setting at E-Color. This will help you adjust your desktop brightness level at
least. You can also try using 3D Deep that comes with the Voodoo 4/5 CD.
In the Display
Customization section you can try using the preset colour schemes or save ones
which you have made, this may be useful for being able to quickly test out
different schemes to see which looks better for you.
You should remember that changing the
brightness settings is largely subjective so you’ll have to play around with
these settings until you find what you believe to be best.
