1. Video Issues
Please note that Doom 3 Demo will automatically configure optimal video
settings based on your computer's hardware. If your hardware changes
after install or if you wish to rescan, in the Main Menu: click
QUALITY button, then APPLY CHANGES. Any change in Screen Size and some
advanced options requires you to quit and restart Doom 3 for them to
take effect.

A. Latest drivers required

For best performance and video quality, please make sure you have the
latest drivers for your video card when running Doom 3. If you have an
ATI or NVIDIA video card, you can find drivers on their websites.

B. Disabling video options to gain performance:

In addition to setting Low Quality, disabling Specular, Bump Maps, and
Shadows will help improve performance. These can be disabled under the
ADVANCED OPTIONS of the SYSTEM menu. Please note that while increasing
performance, disabling these options turns off graphical features that
are key in the Doom 3 experience.

2. Sound Issues

A. Latest drivers required

Please make sure you have the latest drivers for your sound card when
running Doom 3 Demo.

B. The game tells me I don't have surround sound speakers when I do.

If you have surround sound speakers make sure that you have the correct
speaker configuration in the Windows(r) control panel and not only in
any software utilities that came with your sound card.
For Windows(r) XP:
Select "Sounds and Audio Devices" in the control panel. On the
"Volume" tab, click the "Advanced" button under Speaker Settings. Make
sure you have the correct speaker configuration chosen in the drop-down
menu on the "Speakers" tab.

For Windows(r) 2000:
Select "Sounds and Multimedia" in the control panel. Click the "Audio"
tab. Click the "Advanced" button under "Sound Playback". Make sure the
correct speaker configuration is chosen under "Speaker Setup".

C. The sound stutters while playing:

Make sure you have the latest drivers for your sound card. If
stuttering persists try reducing Hardware Acceleration: Click on Start,
then Run. Type "dxdiag" and hit enter. This brings up the "DirectX(r)
Diagnostic Tool". Click on the Sound tab and try reducing the "Hardware
Sound Acceleration Level" slider.

3. Operating system specific issues

A. Shift Key in Windows(r) 2000/XP Interrupts Game

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

"By pressing the SHIFT key five times you have turned on the StickyKeys
feature in Windows(r) 2000 [or Windows(r) 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.

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 labeled "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.

B. Windows(r) Key Interrupts Game in 2000/XP

If the Windows(r) key is pressed during game play, the Start Menu will
interrupt the game. Should this happen, simply press the Escape (Esc)
key to close the menu and return to the game. Unfortunately, there is
no way to prevent this from happening again except by being careful not
to hit those keys while playing.

C. Game Icons Are Missing From Start Menu And/Or Desktop In Windows(r)

When installing Doom 3 Demo while logged into Windows(r) as a specific
user, the game icons will only show up when logging in as that user.
For example, if you log into Windows(r) as "Joeuser", install the game,
then log out and log back in as "Janeuser", the game icons will not
show up. If you wish to play the game, make sure you log into
Windows(r) as the same user you were logged in as when you installed
the game.

D. Admin Rights Needed To Load and Play On Windows(r) 2000 or XP

If you are running Windows(r) 2000 or Windows(r) XP, you must have
Administrator rights to properly install and play the game.



Nightmare mode is not available in the Doom 3 Demo. To enjoy Nightmare
mode, you must have the retail version of Doom 3.
