Deus Ex: Invisible War Demo
README file 11.18.2003


Part 1: Things You Should Know

Please read through the DirectX section of this document. This section has
information that is vital to successfully running the Deus Ex: Invisible War
Demo on your system.


1.1 DirectX

This demo is optimised for Microsoft's DirectX 8.1 (or higher). In order for
you to play the demo, you must have DirectX 8.1compliant drivers for your video
card and sound card. Please note that although DirectX 8.1 is included with
the demo, your video and sound card drivers will not be upgraded to DirectX 8.1
drivers.

You will need to obtain the latest DirectX 8.1 (or higher) drivers from your
card manufacturer or PC supplier. Eidos cannot supply these drivers.

http://www.microsoft.com/windows/directx


1.2 Memory and Performance

While the demo will run fine in 256 MB of RAM, your playing experience will be
smoother if you have at least 512 MB.

Regardless of how much memory you have, you can maximize your available memory
and increase the overall performance of the demo engine by doing the
following:

* Closing any open windows
* Shutting down all other programs, including menu-bar programs like ICQ
* Defragmenting your hard drive

Eidos recommends that you have no other programs running at all while playing
the Deus Ex: Invisible War Demo. Other programs, including virus checkers,
system utilities and screen savers can cause system degradation when playing
demos software and may conflict with the demo for system resources, potentially
resulting in instability and crashes.

WINDOWS® SPECIFIC OPERATING SYSTEM ISSUES

1. Virtual Memory Warnings in Windows® 2000/XP

When playing the Deus Ex: Invisible War Demo on computers using the Windows®
2000/XP operating systems that possess less than 600 megabytes (MB) of virtual
memory may receive low virtual memory warnings. To avoid these warnings,
please make sure you set your virtual memory settings to at least 600 megabytes
(MB).

To adjust your virtual memory settings, please do the following:

For Windows® XP systems:
1) Right click the My Computer icon.
2) Select Properties.
3) Select the Performance tab.
4) Select Virtual Memory.

For Windows® 2000 systems:
1) Right click the My Computer icon.
2) Select Properties.
3) Select Advanced.
4) Select Performance Options.

2. Shift Key in Windows® 2000/XP Interrupts Demo

If you press the Shift key 5 times consecutively in Windows® 2000 or Windows®
XP the following message should appear:

"By pressing the SHIFT key five times you have turned on the Sticky Keys
feature in Windows® 2000 [or Windows® XP]. With this feature, you can lock
down the CTRL, ALT, or SHIFT keys. This is useful if you are unable to hold
down more than one key at a time.

Click OK to turn this feature on. If you do not want to use the feature, click
Cancel.

Turn off keyboard shortcut for this accessibility feature.



"

To avoid this happening in the future, click the Settings button on the window
referenced above. When the accessibility options screen appears, click the
"Settings" button in the "Sticky Keys" portion of the window. On the next
window (should be labelled "Settings For Sticky Keys"), uncheck in the box that
says, "Use shortcut," then click on "Apply," and close the windows. The
problem should not occur once the shortcut has been disabled.

3. CTRL-ALT-DEL Freezes System On Windows® 2000

If the CTRL-ALT-DEL keys are pressed during demo play, the screen will become
corrupt and sometimes the system may become unstable. Should this happen,
simply press the Escape (Esc) key to return to the demo or reboot the computer
and refrain from trying to access the task manager while playing the demo.

4. Admin Rights Needed To Load and Play On Windows® 2000 or XP

If you are running Windows® 2000 or Windows® XP, you must have Administrator
rights to properly install and play the demo.



1.3 Known Issues

Graphics Cards:

1. General
a. It is important to have the most current set of drivers for any video card
you run the demo with. These drivers can be found on the website of the video
card manufacturer.
b. If you are running multi-monitor and you set the second display as primary
in the control panel, the demo will run on the second display, however the
gamma settings will be applied to the first display. The workaround is to
select the first display and check 'Use this device as the primary monitor' in
Display Properties.
c. Some video card/driver combos cause over saturation when light bloom is
enabled. Light bloom can be disabled through the Video Options menu.

2. ATI specific
a. The Deus Ex: Invisible War Demo will not run properly on ATI cards using the
Catalyst 3.8 drivers. We specifically do not support these drivers with the
demo. Running the demo while using these drivers will cause graphical
corruption in-demo, and eventually will cause a crash.
b. While the demo will run properly on the 3.7 drivers, we strongly recommend
updating to the Catalyst 3.9 drivers on the ATI site.
c. The 9700 card does not support 800x600 resolution mode.
d. When running with the 8500 card, the movies and intro screens are slightly
distorted. This does not affect anything else in demo.

3. Nvidia specific
a. IMPORTANT - If you are running with the newest Nvidia drivers (52.16), you
may experience graphical corruption if you are not also using DirectX 9. The
ForceWare drivers require DirectX 9 or higher in order to function properly.
The link to the DirectX site is at the top of this readme.


Performance:

1. If the demo is performing poorly, lowering some of the video settings can
help. Try turning the resolution down or lowering the quality of characters,
shadows, or lighting on the second page of the video options.

2. Other video options may be turned off to help performance
a. Light bloom - this is what gives the light a more radiant "glowing" look.
Turning this off will improve frame rate slightly, and will make the demo look
clearer.
b. Vsync - Turning this off will increase frame rate slightly, but will cause
vertical textures to 'tear' when you rotate.
c. Multisampling - This is an anti-aliasing option. Keeping this set to 1 will
give the fastest performance.

3. Using the Alt-Tab functionality to get in and out of the demo may lead to
demo instability issues.
a. Alt-Tab may cause the mouse to be non-functional within menus. Alt-Tabbing
again sometimes fixes this, but sometimes leads to further instability.
b. If you Alt-Tab out of the demo and your demo resolution is set the same as
your desktop resolution, you may experience problems getting back into the
demo. Generally it is more successful to click on the taskbar icon than to
Alt-Tab back in. There may also be demo interface artefacts left on the
desktop. These should disappear once you've gotten back into the demo and then
exited later.

4. The intro and end game movies may play at less than optimal speed if there
are programs running in the background during or just before they are run. In
order to get the best performance from the movies, we recommend shutting down
all other programs before entering the demo. Using the Alt-Tab during the
movie to go out to desktop and shut down programs will not necessarily help
performance.

Miscellaneous Information:

1. Alt-F4 has been disabled in this demo. In order to exit the demo, press
Escape (Esc) to pull up the main menu and then click on the 'Exit' button. You
will then be given a confirmation window before quitting.
2. All window minimizing has been disabled in this demo with the exception of
Alt-Tab and the Windows key.
3. The demo will begin playing the intro movie if left idle on the start menu
screen for an extended period. To exit out of this movie, press Enter or Esc.
4. There is a trailer for Thief included with the demo. This feature can only
be accessed from the menu with the spinning Deus Ex logo (this menu comes up
when you first launch the demo). To view, select Options in the main menu.
Then select Extras.
5. If your machine has ActiveSync installed and running, the Deus Ex: Invisible
War Demo will not load any map. The Main Menu will come up but once you select
“Start new demo” or attempt to load a saved demo, the demo will crash.
ActiveSync has no means to `close or disable` the program, thus your will have
to change the setting of ActiveSync to not have it interfere with the demo.
The method that is used to change the setting of ActiveSync is to go into the
configuration options and disable all connection settings.




Part 2: Technical Issues


2.1 Installation & Set-up

Preparing Your Hard Drive

To ensure that your installation is trouble free, you should check to see that
your hard drive and file system are both tuned for optimum performance. Windows
comes with two utility programs that find and fix any errors and optimise your
hard drive performance. The first of these programs is called scandisk.
Scandisk will check your hard drive for problems and can fix any that it
finds.

For Win2k:
You can run scandisk by clicking on the Start button from the Windows Taskbar,
followed by Programs, then Accessories, then System Tools, and finally
scandisk.
For XP:
Double click on My Computer. Then right click on your Local Disk (c: by
default). Click on Properties then click on the Tools tab. Click the Check
Now box in the Error Checking section.

Once scandisk has finished running, you should next optimise your hard drive's
performance by running a program called Disk Defragmenter. You can run Disk
Defragmenter by clicking on the Start button from the Windows desktop, followed
by Programs, then Accessories, then System Tools, and finally Disk
Defragmenter.


Installing Deus Ex: Invisible War

Installing the Deus Ex: Invisible War Demo is easy. Simply insert the CD into
your CD-ROM drive. After a few seconds, the Launch Panel will appear.

This program will guide you through the remaining process via onscreen prompts.
If at any time you are instructed to restart your computer, do so.

In the event the Launch Panel does not appear when you insert the CD:

Double-click on the My Computer icon, then double-click on the CD-ROM icon, and
lastly double-click on the Setup.exe file to bring up the Launch Panel.

OR:

* Click on the Start button.
* Choose Run from the pop-up menu.
* Type d:\setup in the box provided (where d: designates your CD-ROM drive
letter).
* Click on the OK button to begin the install program.

You will be prompted to select the path and directory to which you wish to
install the demo on your hard drive. The default is

C:\Program Files\Deus Ex: Invisible War Demo

You may change this if you wish to.

At some point, the Microsoft DirectX 8.1 install prompt will appear if you do
not have it on your system already. Please read the on-screen information
before selecting an option. You may either choose to install or not install at
this time. If the Deus Ex: Invisible War Demo installer detects an active
version of DirectX 8.1 on your system, we encourage you to not reinstall
DirectX. If the installer does not detect DirectX 8.1, you must install it
before you are able to play the Deus Ex: Invisible War Demo (please refer to
the next section of this guide before proceeding).


Starting/Loading The Demo
There are multiple ways to start the demo at a later time. You may

* Double click on the Deus Ex - Invisible War Demo shortcut on your desktop.

2.2 Crashes and Lock-Ups


When I start Deus Ex: Invisible War, my mouse cursor disappears and my computer
locks-up.

Chances are your installed audio card drivers are not compatible with DirectX.
The only solution is to get a DirectX 8.1 compatible driver from your audio
card manufacturer.


When I start Deus Ex: Invisible War, I receive the following error message:

"The application Deus Ex: Invisible War.exe referenced memory at address
xxxx:xxxx that can't be read from."

Chances are your installed video card drivers are not compatible with DirectX.
The only solution is to get a DirectX 8.1compatible driver from your video card
manufacturer.


The Installer keeps stopping when a certain percentage is complete.

There are three likely causes:

* You may have run out of free space on your hard drive. Please remove unwanted
programs to free up additional space for the demo, and then reinstall Deus Ex:
Invisible War.
* Files are possibly being copied to a corrupted area of your hard drive. If
this is so, you'll need to run the scandisk program and make sure to use the
Thorough option (see previous). After scandisk has finished running and has
informed you that your drive is free of errors, try to re-install.
* There may be dirt or fingerprints on the CD-ROM disc itself. Examine the
bottom of the disc; if you see any fingerprints or dirt, carefully clean the
disc using a clean, soft, lint-free cloth by wiping from the centre of the disc
(near the hole) towards the outer edge in a straight line.


Deus Ex: Invisible War Demo is crashing to the desktop with no error messages.

Several different things can cause this problem. Here's a list of the most
common culprits associated with these crashes:

* Make sure the CD-ROM is clean (check for both scratches and smudges on the
reading surface of the CD).

* Make sure the demo has been installed properly.

* Make sure DirectX 8.1 has been installed properly.

* Make sure you have the latest drivers for your video card and that they are
DirectX 8.1 compatible.

* Make sure you have the latest drivers for your sound card and that they are
DirectX 8.1 compatible.

* Make sure Virtual Memory is enabled on your system.

* Run Scandisk.

* Run Disk Defragmenter.

* Clean out old temp (.TMP) files from the C:\WINDOWS\TEMP or C:\WINx\TEMP
directory on your hard drive (from Windows Explorer).

* Make sure you do not have any Anti-Virus utilities (like Norton's AntiVirus)
running resident prior to playing Deus Ex: Invisible War.

* Make sure you do not have any third-party Windows memory management utilities
(like Quarterdeck's QEMM) running resident prior to playing Deus Ex: Invisible
War.

* Make sure you do not have any 3rd party Windows disk caching utilities
running resident prior to playing Deus Ex: Invisible War.

* Make sure you do not have Norton's Crash Protector running resident prior to
playing Deus Ex: Invisible War.

* Try uninstalling and then reinstalling the demo.

* Try exiting the demo, rebooting your machine, and re-entering the demo.


Note that if your system crashes to the desktop while playing Deus Ex:
Invisible War, you should probably reboot your computer before starting a new
play session. Otherwise, DirectDraw or DirectSound may be in a locked state,
and the demo will be unable to use your sound or video hardware.



2.3 DirectX-Related Questions

DirectX has become the new standard in Windows application development. Nearly
all high-performance software will be geared around this technology, so we do
not normally recommend that customers attempt to alter its installation on
their system


Can I Run Without DirectX?

I cannot use DirectX on my computer! Is there any other way to run Deus Ex:
Invisible War?

If you do not have DirectX installed on your computer, you will not be able to
run Deus Ex: Invisible War.
