Patch Overview
Crashes on Save/Load
D3D Slowdown Issues
We have heard of limited success in getting through
level transitions with crashing by temporarily lowering World and Model
Detail to their lowest setting for the transition. These Detail levels
can be raised to their normal levels after the transition has completed.
If you have recurring problems or have problems that
don't provide a useful error message, there have been reports of success
by installing the entire game from a hard drive, rather than the Deus
Ex CD-ROM. To do this:
1) Make sure you have enough space available on
your hard drive for both the installed game and the CD image -- about 1.4GB.
2) Create a folder called "Deus Ex Install"
that will contain the CD image.
3) Copy the contents of the CD into this folder.
4) After it has finished copying, run the setup
file in "Deus Ex Install" and install as you would from the CD.
5) After you have finished installation, you can
delete the "Deus Ex Install" directory.
1) Determine which map is causing the crash
based on the error message. Within the dialog's error message, you should
find something that looks like "01_NYC_UNATCOIsland". You are looking
for something that begins with two numbers and sounds like a location.
Add ".dx" to the end, and you will have the map name. In this case,
it is "01_NYC_UNATCOIsland.dx".
2) Copy that map from the "Maps" directory on your Deus Ex CD to your installed "Maps" directory. In our example, if your CD-ROM drive is "F:" and you've installed to "C:\DeusEx", you would copy "F:\Maps\01_NYC_UNATCOIsland.dx" to "C:\DeusEx\Maps\01_NYC_UNATCOIsland.dx".
3) All savegames that contain data from the corrupted map may also be corrupted, so you should delete any savegame directories that contain the map (with a ".dxs" extension, rather than ".dx"). Start with your most recent savegame -- that is, the one with the highest number -- and work backward, continuing until you find a savegame that does not contain the map in question.
For example, if you have 20 savegames (in your "Save" folder), start with Save0020 and work backward to Save0001. If Save0020 and Save0019 contain "01_NYC_UNATCOIsland.dxs", but Save0018 doesn't, you should delete the Save0020 and Save0019 folders. It is possible that no savegames will contain the map in question, and you won't have to delete any savegames.
4) At this point, you should be able to load your
most recent remaining savegame and continue playing.
From the Main Menu, click on Settings, then Display:
OpenGL is NOT RECOMMENDED for users with 3DFx-based
video cards. Those users should be using Glide for optimal performance.
OpenGL may cause crashes for users with Radeon cards when "Black" or "Snapshot" is selected for the UI/Menu Background option. To prevent this, select "Render 3D".
To enable OpenGL, from Deus Ex's main menu, select Settings, then Display, then Rendering Device. Deus Ex will automatically restart to get to the video device selection dialog. Once you've reached the dialog, click on the Show All Devices radio button. Select OpenGL Support, and then click Next twice and then Done. Deus Ex will attempt to start using OpenGL.
If it fails to do so (displaying an error, or running extremely slowly in a window), your video card or its drivers may not support OpenGL. If this happens you will need to go back to Direct3D as your video device. To do so, simply exit, run Deus Ex via the Safe Mode shortcut it created when it installed, and select Direct3D.
(Advanced users only!) If you are running in OpenGL
mode with a TNT or Radeon card, you might want to try the following to
improve performance:
(Note: when running in OpenGL mode, games that
are saved will not display a screenshot on the loading menu. This
is normal.)
