Deus Ex: Mankind Divided Errors:

#1 Deus Ex: Mankind Divided Crashes

It seems that the game has some certain points in which it will crash, a lot of players complained about Shooting Range, TF29 elevator, Subway loading scene and other scenarios. Also, the game might just crash randomly or at startup as some users complained about this too. To fix the game crashes, either at a certain scenario or random, follow the solution below.

Deus Ex Mankind Divided Crash

#2 Deus Ex: Mankind Divided Mouse Acceleration Bug

Constant mouse acceleration is the most annoying issue in the game. Also, it feels like the vertical axis is slower than the horizontal axis. To fix this follow the workarounds below.

This is a complaint from a user on the Steam Dashboard: “Mouse controls are broken, couldn’t play it myself, will wait for fixes. Basically, the Y-axis is a fraction of the speed of X-axis.  X-axis speed is fine for me, but the Y-axis is one-third the speed of X-axis -> unplayable.”


  • Turn on Vsync
  • Set your mouse sensitivity in game to 0% and use DPI to increase sensitivity

#3 Deus Ex: Mankind Divided DirectX 12 Issue

Currently, this is not an issue of the game because the developers announced that the support for DirectX would come at a later date. So you just need to wait until that happens.

“Contrary to our previous announcement, Deus Ex: Mankind Divided, which is shipping on August 23rd, will unfortunately not support DirectX 12 at launch. We have some extra work and optimizations to do for DX12, and we need more time to ensure we deliver a compelling experience,” the studio announced on Steam.

#4 Deus Ex: Mankind Black Screen Bug

Deus Ex Mankind Divided Black Screen

Some players are experiencing a black screen when they try to play the game in fullscreen mode or when some cutscene appears. If you are experiencing the fullscreen one you need to press Alt+Tab to make the game go in windows mode and after that adjust the resolution of your game to the one of your desktop or vice versa. Another workaround is to use 60hz refresh rate for your screen.

Solution: To quickly fix the black screen issue follow our tutorial at the end of the post and apply the patch to your game.

  • You can also follow this workaround that a player posted on Steam Dashboard:

“I was getting a black screen on this mission and would still hear stuff while the black screen was up and could even quit the game by pressing ctrl alt delete and closing the game. It kept doing the black screen until I changed all of my settings down to off and low and turned off exclusive fullscreen and Vsync and lowered my resolution. So basically a fix for this is to mess with your graphics settings until it launches, good luck! I am getting back to the action.”

#6 Deus Ex: Mankind Divided Breach – Final Reward

Developers reported this: “We have identified an issue where the final reward for Deus Ex: Mankind Divided – Breach is awarded to the player indefinitely, once he continues clearing maps after having completed the game.
As a temporary fix, this reward has been replaced. Once the issue is fully fixed, the correct reward will be put back in place. Users who have completed Breach in the meantime will retroactively receive the reward.

    Just after starting chapter 10 you are given a decision. After I made my choice and got into the bank, my game just flipped out and now I’m getting massive lag issues. It seems to be tied to that big thing hanging from the lobby ceiling (The closer I get, the worse the lag gets and vice versa). I checked my settings as well as my performance monitor, my PC isn’t even close to maxed which tells me it’s the game not the system. Here’s the funny thing though, as long as the game isn’t the active window, it is absolutely fine. If I leave it maximized but bring something else to the front, the game snaps out of it and heads right back to 60 fps like nothing happened.

      Were you able to pass the lobby with the big thing hanging in windowed mode?

    I am NOT completing your idiotic survey just to get your utility.
