Longbow 2 Riva 128 Alpha Display Driver Readme File
12/24/97

1.  Description	
This is a display driver update to allow Longbow 2 to run 3D 
accelerated on Riva 128 cards using Direct3D.  This display driver 
is ALPHA software, and should not be considered complete.  

This driver will allow users of Longbow 2 to choose what kind of 
display driver they use when flying the game.  Users with 3Dfx 
compatible cards can use the Glide display drivers.  Users with 
Riva 128 cards can use the Direct 3D driver.  Users with neither 
can use software driver.

The purpose of this Alpha release to is test the display driver on 
as much hardware as possible before we release a final driver.  As 
it is an Alpha driver, there are some known problems.  The goal is 
that users who use this new driver and find problems will report 
them to Origin so we can address these issues.  See the support 
section for instructions on how to report bugs.

2.  Installation
To install the lb2riva drivers, run the self-extracting archive 
LB2RIVA.EXE in your Longbow 2 directory (typically 
c:\janes\longbow2).  Then run the batch file RIVAINST.BAT.  This 
will patch Longbow 2 to run with Riva 128.

When that is complete, you must make modifications to the system 
to tell it what display driver you want to use.  This is 
controlled by a series of flags in the [INIT] section of the file 
CA.INI.  CA.INI will be found in the root directory in which you 
installed Longbow 2 (typically janes\longbow2).  To modify CA.INI, 
double click on it in the Windows 95 explorer.  It is a good idea 
to back up CA.INI before you change it.  The flags are 3DFX for 
Glide, and D3D for Riva128.  Setting these equal to 1 or 0 in 
combinations will turn the drivers on and off.  Please note that 
there are other flags in the [INIT] section.  Do not modify these.

Here are the individual instructions for running each driver:

A.  TO RUN LONGBOW 2 USING DIRECT3D FOR RIVA 128 CARDS 
Create a flag D3D in the [INIT] section of CA.INI and set it 
to 1.  Create the flag 3DFX, and set it to 0.  The result 
should look like this:

[INIT]
D3D=1
3DFX=0

B.  TO RUN LONGBOW 2 USING GLIDE (3DFX NATIVE)
Create a flag 3DFX in the [INIT] section of CA.INI and set 
it to 1.  Create the flag D3D, and set it to 0.  The result 
should look like this:

[INIT]
3DFX=1
D3D=0


C.  TO RUN LONGBOW 2 USING SOFTWARE DRIVERS (NO HARDWARE 
ACCELERATION)
Create a flag 3DFX in the [INIT] section of CA.INI and set 
it to 0.  Create the flag D3D, and set it to 0.  The result 
should look like this:

[INIT]
3DFX=0
D3D=0

3.  Usage
Once the flags in CA.INI are set correctly, the game will use the 
correct driver if you have the hardware and drivers installed on 
your system.  If you do not, then the game will default to the 
software drivers.

In the game, you will notice extreme improvement in frame rate on 
the Riva 128 if you decrease the horizon distance in the options 
menus.  To do this in the game, hit ALT-O to enter the menus.  
Selection GRAPHICS, then CUSTOM under DETAIL.  There will be a 
slider marked HORIZON DISTANCE.  Move this slider towards the 
left.
