Sneak-peak beta Unreal Direct3D patch for MGA-G200
--------------------------------------------------

version 02

October 1, 1998


This sneak-peak beta Unreal Direct3D patch for MGA-G200 is meant as a preview to the final Unreal Direct3D patch. Due to various technical issues, this sneak-peak patch only runs on a Matrox MGA-G200 based graphics card.


Installation
------------
Make sure to backup your existing unreal.ini file.

Simply unzip the contents of the patch into the your ?:\Unreal\system directory. Say yes to overwrite existing files (if you want to keep your existing ini settings, see instructions below).

Open the unreal.ini file and look for the line CdPath=d:\ within the [Engine.Engine] category and edit it to point to your CD-ROM drive.

Launch Unreal and all should be fine. Note that Unreal first launches in a window - press Alt-Enter to go into fullscreen mode.


Options
-------
The following registry keys can be used to tweak behaviour:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\UnrealD3D

* DoTrilinear (DWORD)
	Setting this to "1" turns on tri-linearing filtering.

* Truecolor (DWORD)
	Setting this to "1" turns on 32-bit rendering in fullscreen.

* DoFlip (DWORD)
	Setting this to "1" flips front and back buffers rather than blting.

* TripleBuffering (DWORD)
	Setting this to "1" enables triple buffering. Triple buffering is only when fullscreen and DoFlip is set to "1".



Issues
------
- this is still a beta patch...
- the game will not load if your desktop color is set to 24-bit
- this patch requires DirectX 6 to be installed
- currently the best driver for use with this patch is beta 4.26, all users are recommended to install this driver for best Unreal performance
- on "weaker" systems, performance may not be optimal
- systems low on RAM may experience slow downs and choppiness as textures are being loaded
- there are still minor visual glitches that are being resolved
- this patch does not currently work with the latest Unreal GAME patches



Saving your existing Unreal.ini settings
----------------------------------------
If you want to keep your current Unreal settings, simply cut and paste the three sections below into your existing unreal.ini file -- the [Engine.Engine] and [WinDrv.WindowsClient] sections must replace those section already in your existing unreal.ini file. The [D3DDrv.D3DRenderDevice] is a new section (make sure to update the CdPath setting).
