ASUS Stereoscopic Driver for Direct3D
-------------------------------------

Important notes before you start to play STEREO games:

1. You must select the following resolutions for stereoscopic modes.
    640x480 
    800x600 
    960x720 
   1024x768 (16-bit color only)

   
How to adjust parameters of Direct3D VR
---------------------------------------
Depth      - Increase it to make the scene look more depth. However, 
             large value could make eyes incomfortable because objects
             are far separated.
Embossment - Increasing it could pull all objects out of monitor
             screen more. You can set an appropriate value by adjusting
             the "E" line on histogram chart of OSD.
Direction  - This option is rarely adjusted because most games use "+"
             as default. If you fail to adjust Embossment parameters to
             make some objects out of screen and the other objects inside
             screen simultaneously, try this option. Currently we find only
             few games need to be adjusted to "-".(See scheme)
Foreground - The option is paired with Background option to "stretch"
             histogram chart to scale your depth of 3D objects. Some games
             only utilize a little range of Z to make bad stereoscopic 
             effect. Adjusting Foreground option to the Z value of objects
             stretched toward 0.0.
Background - Same as foreground except that it sterecth the Z value of 
             objects toward 1.0.
Blind      - If you see garbages on leftmost or rightmost side of screen,
             increasing this value will clear them.


Tips:
1. Do not make 3D objects in games separated to much, especially near objects.
2. It is good to make some objects outside screen and the other ones inside 
   screen. And it is appropriate that the ratio of objects outside and inside
   is 1:3 to 1:5.
3. For car racing games, you can adjust Embossment to make just your car out
   of screen.
4. For first-person-shooting games, just make hand/weapon outside screen by
   Embossment option.
   


OSD Histogram Chart
-------------------

         0                                  1
         |              |            *      |
         |              |            *      |
         |             *|          * * *    |
         |         * ***|     *    * * *    |
         |   * *   * ***|    **   ** * *    |
         +--------------+-------------------+
       Z=0.0            E              ^   Z=1.0
                        ^              |
                        |              Number of vertices on
                        Embossment     this Z-value
                        

You can know what Z range objects locate in and how they gather by this chart.
For example, if this chart is displayed on a car racing game, the vertices on
left side of E" line could be the model of you car and right side could be 
the road, houses, the other cars or trees on the front of your car.

So, you can:
1. adjusting Embossment to move "E" line.
2. adjusting Foreground/Background will stretch the histogram to make objects more
   "even distributed".


Release Notes
-------------------------------------
5.16:
1. New algorithm for stereoscopic computation.
2. New histogram chart in OSD for games utilizing Direct3D 6.0.


Notes/Known issues for specific games
-------------------------------------
Tomb Raider series:
1. Objects locate between 0.95 to 1.0. So you need to adjust Foregound to 95 
or larger.

Beetle Crazy Cup
1. To play this game in stereoscopic mode, you need to set Direction to "-".

ASUS Extra Light Technology for Direct3D
-----------------------------------------------
ASUS Extra Light is very beneficial in D3D game. Users can use Extra Light to define an 
additional spotlight with self-defined direction, size, color, and brightness. It makes 
the 3D scene more bright, clear, and colorful. This technology enhances the color definition 
in 3D games providing additional spotlight to the areas that gamers want to focus on. 

1. Make sure that your applications must run under DirectX 7.0 or later.

2. Open the D3D On Screen Display(OSD)(you may use the defined hotkey), and then press 
Page/UP or Page/DOWN to find Extra Light Setting Page. 

How to adjust parameters of Extra Light Settings
-----------------------------------------------
Enable Light - When selected, this enables you to use ASUS Extra Light Technolohy.
Red Light    - Increasing the red value of the additional spotlight.
Green Light  - Increasing the green value of the additional spotlight.
Blue Light   - Increasing the blue value of the additional spotlight.
Light Cone   - Increasing the size of self-defined light cone of the additional spotlight.
Direction X  - Controlling the horzontal direction of the additional spotlight.
Direction Y  - Controlling the vertical direction of the additional spotlight.

ASUS D3D Games Limitations with VR enabled
-----------------------------------------------
1. Star War II Game : when users enter menu, the screen will shrink into the half size.
2. Rally Game : When playing this game, the screen will flick with VR enabled.
