Deus Ex Setup Guide for modern systems
By Saleck
Deus Ex was made in 2000. Even today it still runs fairly well on the vast majority of PCs but there's no support for Widescreen or any advanced features. Some people find that the game runs too fast or maybe not at all. This guide will help you get Deus Ex running with the New Vision Mod which will greatly enhance your Deus Ex experience.
This guide will help you in setting up Deus Ex on your computer. It's fairly straight forwards in getting Deus Ex set up so let's get to it!
Getting Started
First of all, make sure your copy of DirectX is up to date. You can find the Web Installer to install the latest updates here[www.microsoft.com]

You will also need to install Microsoft C++ 2013 Runtime Libraries[download.microsoft.com] on your machine.

Even if you have any of the above installed and aren't sure about it, you can reinstall them safely as they will either update the current version installed or just reinstall itself.

There are two ways to go from here. You can either:
  • Install the New Vision mod which applies upgraded textures and bugfixed maps OR
  • Skip the New Vision mod completely and have the default Deus Ex experience
I will explain how to install New Vision first, if you are uninterested in the mod. Please skip to the 'Updating Deus Ex' section below.
The 'New Vision' Mod
New Vision is THE Deus Ex mod you should have for your Deus Ex experience.

Not only does it add brand new textures (that stick to the original's artstyle) but it also comes with Bug fixes and a brand new Executable file with advanced functionality for getting Deus Ex looking good and behaving with the high resolution monitors of today.

Head to The New Vision ModDB Page and download the mod. It weighs in at around 1.15GB.

Once you have the mod, Double click the EXE to install it.

Click Next and read the text on the next page carefully.

When you have read the text, press Next.

On the next page, we can choose what renderers and optional extras we want to install.
Here is my personal preference and what I'll be using for the remainder of this guide.

Now the installer will want to know where your copy of Deus Ex is installed. When you have selected the folder your copy is installed in, press Next.

Next, the installer will ask you if you want to install the latest version of DirectX and the Visual C++ runtime libraries (Note that the version of C++ that gets installed with the mod is 2010. The reason I got you to install C++ 2013 libraries will be explained in a while)

I would advise clicking No on both if you've already got these installed but Yes if you are unsure if you have. It doesn't matter either way which you do.

Finish off the installer and close it. We're almost there to getting Deus Ex running but first we need to update the Kentie launcher (which is in the mod) to a newer version which uses Visual C++ 2013 runtime libraries.
Updating Deus Ex
This section is for people who have just installed the 'New Vision' mod and for people who don't want to use New Vision.

You will need to go to Kentie.net's download page[www.kentie.net] and update your copy of Deus Ex with this new executable file (It's the 3rd bullet point down)

Simply download that zip file and extract it to your Deus Ex\System folder, overwriting everything Windows asks you (If you want to make a backup of the old files first though, go ahead).
Configuring the updated Deus Ex
So now, we finally have Deus Ex ready to go!

Go ahead and launch it (either through Steam or just double-click DeusEx.exe in the Deus Ex\System folder) and you'll see the following menu.

You will see this new window every time you launch Deus Ex from now on. Click Configure.

This new configuration menu will allow you to get the most out of Deus Ex.

Here is a run down of what all the settings are:

Default GUI: This setting will allow the in-game user interface (and menus) to stretch and enlarge themselves with the game's resolution allowing for much easier viewing on very high monitor resolutions

1920x1080 example

Non-scaling GUI: This setting will keep the user interface (and menus) at their original sizes. This is good for low to mid resolutions like 640x480 or even 1280x720 but beyond that, you're going to struggle to read on-screen text.

1920x1080 example

Disable mouse acceleration (use DirectInput): Most people will not want to alter this setting. It works fine as is.

Latency: Also best left alone. If you have audio problems or crackling, try changing the value to other recommended numbers

Use DirectSound Best left enabled and untouched

FPS Limit - 100: Change this to 60 for the best experience. Values have no effect on game's running speed anymore so there's no more running around like Sonic the Hedgehog.

Video Options
Renderer: You can change this to anything you want. I highly recommend either 'Direct3D 10 Support' or 'OpenGL Support', there's almost nothing to seperate them from each other in terms of speed and graphical capabilities.

Resolution: Changes what resolution the game will run at. Any value changed here will alter, and take presidence over, any setting in the Field of View section of the menu automatically. You can also specify a custom resolution if you want below and play in Fullscreen or in a Window (Alt+Tab also works but it will default to a 640x480 window if you do)

Quality: Go for 32 bit colour. There is virtually no difference between 16 bit colour and 32 bit colour that I can see. Leave Detail Textures checked.

Field of View: Not really a FOV section but more of a Widescreen section. Any value here tends to be overwritten by any setting in the Resolution section of the menu. Any value here is best left alone as, if you have picked a resolution, the launcher will have selected the best Widescreen selection for you when you chose your resolution.
Custom Launch Options
Having a new DeusEx.exe allows for more flexibility and new launch options can be given to the new EXE to change how it works at startup.

To launch Deus Ex with a Launch Opttion, right click on the game in Steam and click Properties. In General, click Set Launch Options...

You will be given a box where you can enter in commands.

Here are some launch options you can use to further customize Deus Ex.

Games nowadays will save a lot of their information in the 'My Documents' folder but, for people with Solid State Drives or are fussy where their game files go (i.e me), we want the game save files to be stored where Deus Ex is installed.

The new Deus Ex exe saves content inside the 'My Documents' folder by default but it can be changed back to how the original game behaved (saving its content inside the local game directory) by adding the launch option -localdata

This option will completely skip the window you see when starting the new Deus Ex executable which allows you to configure game settings. Use this once you're happy that you have Deus Ex set up the way you want it and you'll no longer have to click 'Play' every time you start the game!
That's it!
OK So when you have all finished configuring your game, click OK to save your options and click Play to start the game.

Enjoy a better, prettier, almost bug-free, and more immersive Deus Ex experience!

I just realized that the effect of FXAA is hard to see in the screenshot, but when you're actually playing it's much more noticable!

And here is a screenshot comparison with both features on and both features off (default+new vision): http://screencast.com/t/xabNjWbl0QB9

Feel free to add this (with credit): If you have an Nvidia GPU you can force FXAA and Anisotropic Filtering for the game. It really makes a difference in smoothing out jagged edges and rendering distant textures. http://screencast.com/t/39k6KRY7ebXF I'm not sure if you can do something similar on the AMD side using their control center program.

For some reason this game doesn't like to play nice with the overlay or minimizing. Does this happen to anyone as well?
I think it only started after installing the mod.

Great guide! Even though I found the New Vision Mod a little wkile ago via googling something like 'deus ex widescreen' :D There's one thing I could add: First I installed Deus Ex on my 3 TB harddrive, what caused a problem hindering me saving the game, when I was playing. In the save window there's a number showing the available disc space and the amount of space the save file is going to take. Because the free space on my 3 TB hardddrive was a number way too big (the available space is shown in MB) there was kind of an overflow and the number went negative leading to the error messga, that there wasn't enough disc space left. :D
I worked around that problem by installing Deus Ex on my smaller SSD and also putting the save files there.

When using OpenGL Support, the game runs too fast for me. I've looked around, and it seems like no one else has this issue. The game runs at proper speed with Direct3D 10, but has issues mentioned by other people here.

Comment to "The Vhampster":
About Revision, who are you referring to as "they"? It's not developed by Square Enix, it's just me and four other persons. We are working as fast as we can. :)

Great guide! Some feedback though:

Currently Kentie's launcher required the VC++ 2013 runtimes, not the 2012 ones.

I'd recommend The D3D9 or the OpenGL renderer instead of the D3D10 because of issues on certain computers/hardware with that renderer. For instance sometimes some surfaces are renderered black and you have to enter the main menu and back to the game to get the surface rendered correctly, others have reported about weird colorization bugs.

Note about the Map Patch fix mentioned in the comments, the New Vision maps is based off that maps patch so you'll get those fixed maps for free. However not sure if all of the map from the patch is in there, so to be on the safe side just install the patch anyway. It won't affect the New Vision maps that live in a separate folder.

Also, no difference between 16 and 32 bit colors? Are you mad?! There is a huge ton of difference.
