Assassin’s Creed 4 Errors, Crashes, Graphics, Launch Problems and Fixes

By   /   2 years ago

This time around, you are going to re-live Edward Kenway’s legacy in Assassin’s Creed 4: Black Flag. Being a Pirate Assassin sure is a cool idea and Ubisoft has executed it perfectly.

After the game’s release on consoles, PC users had to wait more before they could also relish the joys of sea battles. It’s a usual practice that developers adopt these days so that they can get sufficient time to port the game to PC.

Anyhow, the wait is over as Assassin’s Creed 4: Black Flag has been released to the PC community. Although the game looks great on PC, it has some minor issues that need some attention.

Most of them can be resolved using temporary fixes and workarounds. So if you are looking for a fix, I will recommend that your browse through the workarounds listed below:

#1 Assassin’s Creed 4 Resolution Problem
Some users (especially the bootcamp users) have reported that the interface is appearing blurry and they can’t read anything. First thing you should do is update your drivers as Nvidia has rolled out an update optimized for Assassin’s Creed 4.

If your drivers are up to date, you should try changing the native resolution of your desktop or try running the game in windowed mode. If the text is blurry for the MAC Bootcamp users, they should make the text size 100% from the desktop graphics settings.

#2 Assassin’s Creed 4 Launch Errors
Since it’s a Uplay based title, launch problems are expected. You can do a few things to launch AC4 properly:

  • If you are getting an error that Uplay has stopped working, you should try re-installing Uplay manually.
  • If you have a problem where you press play and nothing happens, I will recommend that you try launching the game as admin through the AC4’s original “.exe” file.

#3 Assassin’s Creed 4 Screen Tearing Fix
There are chances that you might experience screen tearing on your machine even if you are meeting the recommended system requirements for the game. You can try a few tweaks to fix it.

  • Make sure that you haven’t forced Vsync to off from your Graphics Card’s software.
  • You should disable the in-game Vsync and force tripple buffering using any third party tool.
  • You can also use any software to limit your frames to 56-60. This can help in reducing the screen tearing effect.

#4 Assassin’s Creed 4 FPS Fix (Recommended for Nvidia Users)
If you experiencing FPS drops and you are using a Nvidia card, I will suggest that you use the following workaround:

  • Right click desktop->Nvidia control panel->Manage 3d settings->Program settings-> and select Switch power management mode.
  • You should change the option to “Prefer maximum performance”.

If you are using a laptop, it’s recommended that you plug in your charger to experience better performance.

#5 Assassin’s Creed 4 Multiplayer Crash Fix
Users who are facing multiplayer crashes should try the following fixes:

You need to find mp_ini file for Assassin’s Creed 4 in your documents. Delete the file and when you launch the game next time, a new one will be created and you will be able to play normally.

If you are using multi-monitors, you should try using the single screen to fix it. It’s not a permanent solution but that’s all you have got till Ubisoft patches it up officially.

#6 Assassin’s Creed 4 – Uplay Not Connecting Fix
It seems like that Uplay is not too friendly with proxy related configurations. If you can’t manage to connect the software, you should first try downloading a new copy from the official website.

If that doesn’t solve the problem for you, you should go to C:\Windows\System32\Drivers\etc and delete the files named as “hosts”. This should fix the issue.

#7 Assassin’s Creed 4 – Cannot Download Fix
If you aren’t able to start the download, there are a few things you should try:

First, make sure that your firewall/antivirus/security tools aren’t interfering with the downloading process. These tools may consider some Uplay files as a threat (they are false positives) and hence stopping the download.

Disable them momentarily to see if the download continues. You can then add an exception later on to make it work.

#8 Assassin’s Creed 4 Error – AC4BFSP.exe has Stopped Working
If you haven’t restarted Steam after downloading the game, I will recommend that you do that first. Make sure that you have up-to-date drivers for your GPU. After updating drivers, you must restart your PC to make the changes work. Verifying game files has also fixed the problem for some users.

#9 Assassin’s Creed 4 Sound Issue Fix
I am not sure that this fix will work for you or not but it has helped some people out there (also with the previous assassin’s creed games). So, here goes:

  • In Start menu, go to run and type DXdiag in it.
  • After the directx window opens, go to the sound tab.
  • Here, you should try lowering the sound acceleration.

Try it and let us know in the comments whether it fixed the problem for you or not.

  • JCstiggy

    Not sure what this problem is called, but whenever I run AC4, I’m getting a constant pull on the controls in one direction. Sort of like when controllers messed up and there is a constant input to the left or something even though you aren’t touching the joystick. I was trying to use an Xbox One controller initially with VJoy, so I uninstalled it, but still no luck. Controls are always pulling in one direction, making the game unplayable. Any solution?

  • Grey

    Question: 90% of the time, when I start AC4, the Logo of Ubisoft etc etc won’t show up, but I do hear the sound, after that I get the menu, I can play, but it looks like no textures were load. So the gameplay is VERY dark!
    Yesterday I updated my videocard, I ran the game, and it worked fine!
    Today,… back to black…

    Any idea?

    • Deryl

      Have the same problem! From time to time Pers just start to walk back and no other control work any more – only ESC. When press ESC, there is the same problem. Looks like down arrow is pressed, but it its not. Restart of game helps. But you never know for how long :(

  • Kevin

    • rattlesnake_906

      Are you playing Steam version? Is your cloud feature turned on?

  • MHolguin87

    I’m having a problem with the game itself. My Xbox is saying that the disc is unreadable and I should clean the disc with a soft cloth and restart the console. It was giving me such a problem that I went and returned the game for a new one. That seemed like the logical choice. I started playing the new one, and it’s doing the same thing all over. And I’ve tried using two different xboxes, any suggestions??

    “If the text is blurry for the MAC Bootcamp users, they should make the text size 100% from the desktop graphics settings”

    Widows 7 here. Had text zoom on since hooked up to the TV. This fixed everything, blurry menu, choppy audio, poor graphic quality.

    Thank you!

      • Unhuman

        i too had the smae problem but fixed after i updated my graphic drivers to latest

    • Honorable Sir

      I have the same problem. Though I can get it to work. Once you launch and it goes into Uplay. before hitting “Play”, click one of the links to open the Forums. (it’ll launch your browser). then click play (without closing anything) and the game should start. This has worked every time for me. I’m running on a laptop M14X A-Ware, and the game is just flunky with drivers. Hopefully they’ll fix it eventually.
