How to fix Assassin’s Creed Syndicate Errors: Crash, Lag, ACS.exe has stopped working and more

Ubisoft is here with yet another installment in the popular Assassin’s Creed series. Assassin’s Creed Unity faced criticism among fans for poor optimization on PC and consoles. Seems like Ubisoft developers have learned a lesson from it. Unlike Unity, Assassin’s Creed Syndicate has lot less issues on PC and consoles. But we have still heard of a few common PC errors like no sound, stuttering and severe lag that the users are facing.

 

We present you this guide to teach you how to fix the most common issues and errors encountered in Assassin’s Creed Syndicate PC version.

How to fix Assassin’s Creed Syndicate Errors: Crash, Black Screen, Server Issue, Freezing, Stuttering and more:

 

#1 No sound in Assassin’s Creed Syndicate fix:

To fix this issue

  1. Press Win+R
  2. Type “dxdiag” without the quotation marks and hit enter
  3. A new windows pops. Now go under Sound tab and lower the Sound acceleration from there
  4. Launch the game

This fix didn’t work for some users so we have to wait for an official patch from Ubisoft.

 

#2 Crash during startup/random crashes/black screen/failed to launch fix:

  • Players who are facing issues like the game crashing to desktop while launching or during gameplay should try updating their video card drivers. We suggest users to do a clean install of the video card drivers by downloading them from the official website.
  • If you have the game on Steam, we suggest you to verify the game cache to avoid such errors.
  • Another simple but useful method is to play the game in Compatibility mode. For this, right click on the game’s .exe and click Properties. Under the Compatibility tab, set the Compatibility mode to either Windows XP SP3 or Vista.
  • Users with SLI/Crossfire setup can try disabling it and laptop users should use the dedicated GPU instead of the integrated one

 

#3 Stuttering/Micro-stuttering in Assassin’s Creed Syndicate fix:

This issue is solved by disabling VSync from the graphics settings in the game.

 

#4 ACS.exe has stopped working error fix:

This issue has been faced by many users. You can fix this error by following the steps

  1. Right click “This PC” from desktop and click Properties
  2. Go to Advanced System Settings from left column
  3. Click Settings in the Performance section
  4. Under Data Execution Prevention enable Turn on DEP for all programs and services except those I select
  5. Select ACS.exe by browsing the installation folder and click Apply
