Call of Duty: Black Ops 4 King 177 Jaded Mamba, Crash At Launch and Fixes

Black Ops4 is the latest entry in the long-running franchise. The game is the series’ first to feature a Battle Royale mode and not feature a single-player campaign. With Blackout mode, Activision expects the franchise to reach new levels of popularity.

However, PC gamers have been facing issues with the game including the Black Ops 4 King 177 Jaded Mamba, NAT Type Error and more. Here we will discuss them all along with their fixes and workarounds.

Error: King 177 Jaded Mamba

Black Ops 4 King 177 Jaded Mamba is one of the issues that players are experiencing. There is a simple workaround to this problem. Open Battle.net and select the “scan and repair” options.

This will find any missing files or corrupted files and will allow you to play. However, some of might have to do “scan and repair” every time you close the game. I recommend that you make an exception for the game’s install folder in your anti-virus or Windows Defender. This will resolve your Black Ops 4 King 177 Jaded Mamba error.

Crash After Intro Video Fix, Crash At Launch

This is another one of the errors that players have been experiencing. Here are a few things you can do to fix this issue.

One fix for this problem is, navigate to C:\Program Files (x86)\Call of Duty Black Ops 4\LPC and delete the files here. Now open up Blizzard.net and “scan and repair” the game. This will resolve your crash at launch issue.

Another reason for the crash could be your anti-virus software or Windows Defender. Either disable the anti-virus or make an exception for the game in your anti-virus program. This will resolve your issue.

If all of above don’t work for you, then you might be using a factory overclocked GPU or have overclocked it yourself. Using the MSI Afterburner try reducing the GPU’s clock speed, this should resolve the crashing issue for you.

However, if none of the above have worked then try out the following step-by-step.

  • Scan & repair game files
  • Update GPU drivers, update Windows
  • Change page file settings – manual, automatic
  • Selective startup – disable all non-Microsoft services
  • Uninstall any programs that interfere with GPU – F.Lux, MSI Afterburner
  • Run standard Battle.net as normal
  • Run standard Battle.net as administrator

No Audio Fix, Audio Issues

Players have reported that while playing Black Ops 4, they don’t get any sound except for their friends on the chat. The issue might be the audio driver especially if you are using onboard audio.

Uninstall the audio driver completely and try deleting using the Revo Uninstaller for a clean uninstall. Now restart the PC and your OS will install the audio driver. This will resolve the problem. Do the same if you are using a dedicated Sound Card.

Players are also experiencing issues like incorrect audio or issues with the surround sound. The problem might be wrong channel selected for your audio device.

Open PlayBack devices and select the audio device that is being used. Now click on “Configure”. Here select the right channel for your headphone or speakers and go with the prompts. This should resolve the problem.

100% CPU Usage Fix

PC players are experiencing 100% CPU usage with Black Ops 4. The issue is the game not recognizing the correct thread count of the CPU. The fix is quite simple.

Go to Black Ops 4’s install folder and open Config file in notepad. In the file look for the following:

//Thread count for handling the job queue worker_threads = “X” // 2 to 8

Just replace the X with the correct number of thread count for your CPU. Meaning if your CPU has 4 threads then replace X with 4. The game by default doesn’t recognize the right thread count which causes 100% CPU usage along with stuttering and FPS drops.

NAT Type Error

NAT is common in multiplayer games with Black Ops 4 being no exception. However, the fix for NAT Type error is pretty easy as you can just change the NAT Type. Just follow the following steps to fix this problem but first, make sure you are using a wired connection, not a wireless one.

  • Disable the firewall for your Router.
  • Set port forwarding to your own IP address of the device.
  • Use port 3074 UDP and TCP.
  • Enter your IP in the DMZ of the router.

This should resolve your NAT Type error and allow you to play Call of Duty: Black Ops 4.

Blank Tab In Battle.net, Unable to Install

While the game has launched but some players are unable to install the game due to the Black ops 4 tab being blank in Battle.net client. The fix is quite simple.

Log out of the client and log back in but change your region. This will load the tab and you will be able to download the game. After that, you can just change the region back to the original one.

Salvo Rocket Launcher Crashing The Game

This a rather unusual error or issue with the game but the workaround is quite simple. Just scan and repair the game and the issue should resolve. The problem might persist, so might have to scan and repair every time you close the game until a permanent fix is rolled out.

Game Not Joinable

This is another error that Black Ops 4 players are experiencing. This issue might be with the NAT Type so change is using the steps detailed under “NAT Type Error”.

A simple fix also exists which is just restart the game and log in. This should resolve your issue.

Black Screen Fix, Blank Screen With Audio Fix

Players have reported that they are experiencing the black screen issue with the game. According to players, when they start the game they only see the black screen with the game’s audio in the background.

Start the game and when the black screen appears, press “ALT+Enter”. This will put the game in Windowed mode and you will have the display. Now go to video settings and change the resolution to your monitor’s native resolution and you will be able to play the game in fullscreen.

Low FPS Fix, Performance Boost

While Black Ops 4 is an optimized game designed to run at 60 FPS but still players are having issues with running the game at a smooth FPS. Here are a few things you can do to fix this.

Update your GPU driver, make sure no background process is using too much of your CPU or HDD. Also, try cleaning up the Windows registry as some unnecessary registry files can cause performance issue.

If you have a Nvidia GTX 10 series GPU or above, then open Nvidia Control Panel. Select “Manage 3D Settings” and then select program settings. Select Black Ops 4 from the list and then go through the options looking for V-sync and set it to Fast. If you have the GPU and CPU that can handle it then you will get a locked 60 FPS experience.

While the Nvidia Control Panel is open, try to make changes to the other settings for Black Ops 4 to the following.

  • Texture filtering – High Performance.
  • Power Management Mode – Adaptive or Prefer maximum performance.
  • Multi-Display/Mixed GPU Acceleration – Single Display Performance Mode (If you are using a single display)
  • Threaded Optimization -Enable.

That is all for our Call of Duty: Black Ops 4 King 177 Jaded Mamba and other issues along with their possible fixes and workarounds.
