MODIFIED 11/4/97

CHANGES

Added "r_refreshrate" variable (default: 85) to determine fullscreen refresh rate.


=============================================

This is the beta 5 release of VH2 (Verite Hexen II).  It requires a Rendition Verite-based
graphics card (such as the Canopus Total 3D, Sierra Screamin' 3D, Intergraph Intense 3D 100,
or Creative Labs 3D Blaster PCI).

To install VH2, just copy the vh2.exe program into the directory where you installed the
full retail version of Hexen II.

Notes:

This release of VH2 will only work with the version 1.11 (or newer), full retail release of 
Hexen II.  If you have the Hexen II demo, we are still waiting to receive the demo build 
from Activision.  Hopefully we'll have that soon.

If you have not yet patched your retail release of Hexen II to version 1.11 or better, you 
can download the patch from 
    http://www.activision.com/games/action/hexenII/index.html

VH2 requires Verite Windows 95 drivers which support RRedline.  If you do not already 
have drivers from your card manufacturer that support RRedline, check their web site.  If 
they are not yet available, they should be soon.  In the meantime, try checking some of the 
end-user Rendition web sites (such as http://www.users.wineasy.se/bjornt/bt3d.html).  Note 
that reference drivers obtained from one of these sites are not supported by Rendition or 
any Verite-based graphics card manufacturer.  They are provided for test purposes only; 
use them at your own risk...

Compatibility issues:
	* Canopus' 2.20.06 drivers overreport the amount of video memory in the system, 
	  which generates an invalid modelist.  Trying modes above 768x576 may produce 
	  bad results (like crashes).  Try the Rendition reference drivers.

	* Creative Labs' RRedline beta drivers from May 8, 1997 have a microcode bug 
	  that prevents particles from being drawn.  You can either get the v10003d.uc 
	  file from Rendition's reference drivers, or use 
		r_antialias 4
	  to draw round particles, which do draw correctly

	* Intergraph's RRedline beta drivers have a microcode bug that prevents particles
	  from being drawn.  You can either get the v10003d.uc file from Rendition's
	  reference drivers, or use 
		r_antialias 4
	  to draw round particles, which do draw correctly
	  In addition, running the game will corrupt the Windows system palette on 
	  Intergraph's drivers.

VH2 will only run on a 16-bit desktop display setting.

Available video modes are determined based on available video memory.  Windowed modes
must take into account the video memory gobbled up by the desktop.  It is therefore
possible to get a different mode table if you run the game from a different sized desktop.
Video mode numbers will not, therefore, be consistent from run to run if you change your
desktop size.  So don't be surprised if your _vid_default_mode_win doesn't set the mode
you think it should...

New command line variable(s) (VHexen2 *only*)
=============================================
r_antialias (default 0)
    will antialias one or more of the world, objects, and particles (like in GLHexen2)
	1 = world
	2 = objects
	4 = particles

    add one or more of these together to antialias any combination.  For example:

		r_antialias 5

    would antialias the world and particles

r_nomurk (default 0)
    if set to 1 will disable the screen colorizing that happens when you are underwater
    (or in any "non-air" substance)

r_surfacelookup (default 1)
    determines whether the Verite (value = 1) or the CPU (value = 0) should
    translate textures into 16 bit format.  This is a performance tweak that gives
    different results at different resolutions and on different processors.  Try
    it for the resolution(s) you like.  Your mileage may vary

vid_interleaved (default 1)
    on the V1000, with sufficiently new display drivers, will interleave scanlines of
    the front, back, and Z buffer to improve performance.  If interleaving is not supported
    (or is not ideal, as in the case of the V2x00) VH2 will set this variable to 0

***** NEW *****
r_refreshrate (default 60) 
    Refresh rate in Hz
    determines the refresh rate for fullscreen modes.  Valid values are >= 1.0, but the
    actual refresh rate will be constrained to valid values.  The minimum refresh rate
    is typically 60, so any value below that will give 60Hz.  Any value that is not a
    valid refresh rate for the given mode will select the highest refresh rate below the
    specified value.
    Will not take effect until the next mode set.

Other files in this ZIP:

v10003d.uc:  the RRedline microcode which fixes the particle bug on the Creative and
	Intergraph RRedline drivers discussed above.  To prevent problems with other 
	programs, put this file in the Quake 2 directory.

v100032.dll: the DirectDraw driver for the V1000
	If your current display drivers do not support the interleaved display on the V1000, 
	replace the v100032.dll in your windows\system directory with this one.  This driver 
	must be in that directory to function.  Be sure to make a backup of your existing 
	driver before using this one.  Also note that if you are using your card 
	manufacturer's drivers, the name if the driver may be different.  This is a hack,
	and may cause serious problems, so be careful...
