Deus Ex Mankind Divided

Deus Ex: Mankind Divided is out now- and as is the case with just about any release these days, major AAA or indie, its PC version comes with its own fair share of errors and problems, which can significantly hinder your enjoyment of the game.

The good news here is that the game isn’t totally broken or bonked on PC, as is so often the case of late- instead, we just have a relatively decent PC version, which works fine, but comes with its own fair share of issues. If you experience any of them, you’ve come to the right place- this guide will help you deal with most of them.

But first, the specs:

Minimum Requirements

  • OS: Windows 7 SP1 (64-bit)
  • CPU: Intel Core i3-2100 or AMD equivalent
  • RAM: 8GB
  • Graphics: AMD Radeon HD 7870 (2GB) or Nvidia GeForce GTX 660 (2GB)
  • Storage: 45GB

Recommended Requirements

  • OS: Windows 10 (64-bit)
  • CPU: Intel Core i7-3770K or AMD FX 8350 Wraith
  • RAM: 16GB
  • Graphics: AMD Radeon RX 480 or Nvidia GTX 970
  • Storage: 55GB (including DLC)

Please be advised that the following methods are to be used at the sole discretion of the system owner. GamingBolt or its staff members take no responsibility for problems that may arise or issues that may occur from trying the below. Always remember that official support is always the best support. 


This appears to be a common error on the PC version that a lot of players have been reporting- at least, it seems to be common enough that the developers have stated they are investigating it officially. Until an official fix is issued, however, players have discovered some workarounds to avoid the problem. The list of known common fixes to the problem follows:

  • Lower the games graphic settings
  • Deselect DLC content from the game’s properties in your Steam library list
  • Run the game in windowed mode
  • Turn off the subtitles


This occurs when the game’s options menu does not display the settings correctly. A fix for this error is coming- until then, players just need to ignore what the menu says, and go by what they see in the game.


One of the most annoying issue with the game is its constant mouse acceleration, which leads to highly unpredictable mouse tracking in game. A suggested fix for the problem has been found- bear in mind it may not necessarily work for you, however:

  • Select Options in game main menu
  • Set the mouse sensitivity option to 0
  • Confirm the settings, and restart the game


The game has an error where the final reward for Deus Ex: Mankind Divided, Breach, is awarded to the player indefinitely. For now, the developers have replace the final reward of the game with something else, but a fix is coming, and Breach will be made available to all those who should have earned it retroactively upon the fix being made available.

Optimizing PC Performance:

Please use the following guidelines released by the developer to optimize your Mankind Divided experience on the PC.

There are simply suggestions for different quality levels, feel free to use them, but for the best experience tuned to your personal preference, please tune the other options below and have this be Custom.

Texture Quality
This alters the resolution of textures used in the game. This primarily impacts GPU memory pressure. If this is set too high the game may start stuttering and slowing down. It does not impact performance on the GPU or the CPU much otherwise. We recommend it at High for 4GB cards. You have to restart the game to apply changes to Texture Quality.

Texture Filtering
This is an all-time PC gaming classic. Turn it up for sharper textures at an angle. We feel that the moderate amount of 4x gives very good results. Altering only impacts GPU performance.

Shadow Quality
This setting impacts the resolution of shadows rendered throughout the game. At high settings shadows become crisp and lose pixelated artifacts. At lower settings they are chunkier. Altering only impacts GPU performance. Very high can be relatively expensive for the GPU.

Contact Hardening Shadows
Turning this on creates more realistic shadows as they move away from their source. This only impacts GPU performance.

Temporal Anti-Aliasing
Toggling this on will reduce aliasing to create a smoother image. This only impacts GPU performance.

Motion Blur
Fast camera and object motion will appear smoother. This only impacts GPU performance.

Depth of Field
Depth of Field can blur areas on screen that are out of focus, typically when far away. This only impacts GPU performance.

When turned on bright spots on the screen will bleed out, adding to the illusion of bright light. This only impacts GPU performance.

Volumetric Lighting
Turning this on adds volumetric lighting to some fog and smoke effects. This only impacts GPU performance.
Setting it to Ultra increases detail but has a significant impact on GPU performance!

Subsurface Scattering
Improves lighting effects on the skin of characters in the game. This only impacts GPU performance.

Cloth Physics
Disabling this reduces the quality of cloth simulation. This only impacts CPU performance.

Ambient Occlusion
This toggles on and between different ambient occlusion algorithms. This only impacts GPU performance.

Turning this option on smooths selected meshes throughout the game by tessellating them. This option impacts GPU performance, and to a lesser extent CPU performance.

Parallax Occlusion Mapping
Adds additional depth and detail to select surfaces, such as brick walls and cobblestone streets. This only impacts GPU performance.

Screenspace Reflections
When this option is turned on dynamic reflections are calculated based on other items visible on the screen. Turning it up to Ultra gives you more detail in the reflections. This only impacts GPU performance.

Sharpen & Chromatic Aberration
Camera effects that can be toggled on or off. This has a minimal impact on GPU performance.

Level of Detail
This influences the detail level of rendered meshes, and the distance at which they disappear entirely. Lower settings can significantly help CPU performance due to it having to process fewer objects. GPU performance is also impacted.

Note: Given that the wide range of PC hardware out there, the fixes mentioned here may or may not work for you. But it’s worth giving them a shot since these have worked for players who own the PC version of Deus Ex Mankind Divided.
