Basic Guide for Playing Deus Ex in 2025

I'll be doing this guide based on what I've encountered so it may not be comprehensive but it will be very easy to follow.

Let's Begin

Having low FPS and really small screen resolution may be the first things you encounter when you start the game, don't worry it has an easy, 2 step fix.

Download Kentie's Launcher (Deus Exe Launcher)

Kentie's Launcher helps you configure the game, and includes a mod manager so it is much easier to run it on a modern computer.

1. Go to this page[kentie.net] ( https://kentie.net/article/dxguide/ )
   
2. Download the latest version of the launcher under the "Downloads" title.
   
3. Place the contents of the DeusExe zip file in your Deus Ex 'System' directory, you can find this folder by opening the Deus Ex download folder from Steam

Download a Renderer

1. Go to this page[www.cwdohnal.com] ( https://www.cwdohnal.com/utglr/ )
   
2. You'll see a very old page, navigate to the "For Deus Ex (works with Deus Ex version 1112fm)" part
   
3. Download one or both of those renderers (i use OpenGL)
   
4. Place the contents of the zip file(s) in your Deus Ex 'System' directory, you can find this folder by opening the Deus Ex download folder from Steam

WARNING
Even though my pc is fine after the download, Virustotal says this site is malicious (3 of the 4 antiviruses that flagged the site says it's phishing), download at your own risk.

Minor Adjustments

After doing all these, You might find your cursor stuck on the top left of the screen.

If so, run the game again and and before pressing Play, press Configure and enable Raw Input and disable FPS limit by lowering it down to zero.

Although I can't think of a way to fix your issue, reinstalling and trying again or checking if you have missing files might worth a try @Keyaiel

[yussuf]

Glad to hear that @TheCodeTinkerer

[yussuf]

@NeoTokyo, it did fix many issues for me but I don't know if it includes those, sorry

[Keyaiel]

Can't seem to get it to work at all after putting what I could download in the systems folder.. Not sure what I'm doing wrong =/

[TheCodeTinkerer]

Worked like a charm - I only did the Kentie's launcher import for win11 using GOTY Steam edition.

[NeoTokyo]

does this custom launcher include and fan patches to fix issues or should i go looking for those?

[yussuf]

@Munoobinater

Yeah the file seems to be fine but like you said, site is flagged.

Also you do have a built in flashlight augmentation, press F12 to enable it, but enemies react to it if i'm not mistaken.

[Munoobinater]

ok the game is very dark, its legitimately hard to see and im on the first mission... any help?

[Munoobinater]

So the website is flagged by virustotal, but the actual file, if u upload it to virustotal, it safe

[yussuf]

Glad to know that, same goes for me too, I had no issue so far and I ran a lot of checks using Malwarebytes etc.
