Update Your Drivers

Assassin’s Creed IV Black Flag was initially released in a stable state. However, if you meet the game’s minimum system requirements and are still experiencing crashes, it is likely that an outdated graphics driver is the primary cause. To resolve this, we strongly recommend that you obtain the latest update for your PC by visiting your hardware manufacturer’s official website.

Manually downloading and installing drivers for your PC can be time-consuming and somewhat complex for some users. For those looking for a more straightforward approach, we recommend trying IObit’s Driver Booster. This software is able to automatically download and install the most recent and necessary driver updates for your PC. We used Driver Booster to update and fix crashes and performance issues in Assassin’s Creed IV Black Flag. Here are the steps you can follow to use the software:

Download and install Driver Booster from its official website.
Run the Driver Booster application.
Click the “Scan” button to initiate a scan of your system’s drivers.
Once the scan is complete, review the scan results to identify any outdated or corrupt drivers.
Click the “Update Now” button to download and install the latest driver updates for the identified devices.
Optionally, you can select the “Update All” button to update all outdated drivers with a single click.
Follow the on-screen instructions and prompts to complete the driver update process.
When the update is complete, restart your computer.

Note: During the driver update process, your PC may restart several times, depending on the drivers being updated. This is a normal occurrence for the Windows operating system, so don’t be alarmed.

Once the driver update is complete, continue to run Assassin’s Creed IV Black Flag and see if the problems you experienced earlier persist.

Verify Game Integrity

If you have tried the above methods and are still experiencing problems with Assassin’s Creed IV Black Flag, you can attempt to verify the game integrity of Assassin’s Creed IV Black Flag. Steam will scan all necessary files and repair any damaged files associated with Assassin’s Creed IV Black Flag. This may help to resolve the issues you are experiencing.

Open Steam and go to Library.
Select Assassin’s Creed IV Black Flag from the game list on the left side.
Right-click and select Properties.

Check out the image below for the steps.

Right after you click the Verify button, all you have to do is wait for Steam to finish verifying the file for Assassin’s Creed IV Black Flag.

Kill Resource-Hogging Applications

It is likely that you have many applications installed on your PC, and some of them may be constantly using system resources, potentially causing Assassin’s Creed IV Black Flag to crash. To mitigate this problem, we strongly recommend that you close any software that you are not actively using while Assassin’s Creed IV Black Flag is running. This will free up system resources and minimize the chances of Assassin’s Creed IV Black Flag crashing.

Media players, web browsers such as Firefox and Chrome, and other similar software are known to consume a significant amount of system resources when they are running in the background. To free up resources, you can terminate these applications by using Task Manager and shutting down the application.

Disable Antivirus

Another possible cause of frequent crashes of Assassin’s Creed IV Black Flag on your PC could be related to your antivirus software. Antivirus companies update their software on a regular basis to improve the security measures, but sometimes these updates can mistakenly identify the executable file (.exe) of Assassin’s Creed IV Black Flag as a virus.

To resolve this problem, you can try to disable or temporarily turn off your antivirus or other security programs on your computer. If you downloaded Assassin’s Creed IV Black Flag from the official store, the game files are most likely safe. In this case, you may want to consider excluding Assassin’s Creed IV Black Flag’s .exe file from being scanned by your anti-virus software, and see if the problem still persists.

We have compiled a selection of commonly used anti-virus software along with the corresponding FAQs.
