Stereo3D-Quake and VFX1

Okay did some more testing if any of you find different 
results please email me.

I have quake 1.08 (dos) winquake (1.09) and hexen 2 demo.
vfx1 works in stereo in all three games which means most
likely all the quake games coming out this winter will
have 3-d support right out of the box.  Here are my 
findings.

in winquake I had to use the command line switch
-dibonly to get the vfx1 to work (this disables
the direct x and vesa drivers and uses only the
win95 drivers).  The vfx1 would only work in
640x480 full screen video mode. Make sure 
to have force stereo mode checked in vfx1
applet. 

hexen 2 worked with no command line switches at
all. It also only worked in the 640x480 full
screen video mode. Make sure to have force
stereo mode checked in vfx1 applet.

dos quake worked with no command line switches
also. It would work with 320x480, 360x480, and
640x480.  obviously there is a pattern here:
only vertical pixel modes that are 480 work with
the vfx1 in stereo mode.  Make sure to run
vfx1 +t prior to quake so that vfx1 is forced
to stereo mode.


Now to the console commands:

Basically to turn on the stereo mode you type:

lcd_x 1.0

to turn it off type:

lcd_x 0

You can also increase or decrease the stereo
separation by increasing or decreasing the number.
I found lcd_x 1.5 to give the best effect without
eyestrain.

ALSO THIS IS VERY IMPORTANT.  the 3-d effect is 
wrong if using positive numbers. by using a 
negative number switches the left/right
prominent eye (sorry I don't know the proper
term).  The setting I use is:

lcd_x -1.5

The easiest way to fool with the settings
without typing in the console every time is
to:
edit the vfx1.cfg file that is in the id1 
directory

add the following lines
bind "y" "lcd_x 0"
bind "u" "lcd_x -1"
bind "i" "lcd_x -1.5"
bind "k" "lcd_x -2"

this should allow you to play with the
separation settings with a full screen
showing in the game.  Also this mode
is perfectly compatible with the old
vfx1 quake headtracking driver 1.0  I have not
checked it with the current one.  Also
there is another setting lcd_yaw that
I have not messed with.  There might be
other settings too that I have not found.
