Call Of Duty Modern Warfare 3 was released only a few days ago but already bears the barrage of errors like the MW3 Error Code 0x887a0005. This is one of the most notorious errors that has plagued the previous entries as well and has now surfaced in MW3.

This has been leading to gameplay issues ruining the pre-release experience. Multiple factors contribute to the cause of this error, such as hardware issues, corrupted game files, outdated drivers, third-party in-game overlays, overclocked components, and insufficient game permissions, but not to worry, as there are various ways to resolve this error.

If you use Steam to play Modern Warfare 3, the pop-up error window displays: “The application has unexpectedly stopped working“.

Key Takeaways

These methods can ensure that the error will no longer be a problem for you anymore:

  • Verifying game files through Steam.
  • Run MW3 On the launcher.
  • Close unnecessary background applications and services.
  • Disable hardware acceleration.
  • Switch from NVIDIA’s DLSS to AMD’s FSR settings.
  • Update the GPU drivers.
  • Disable XMP.

Verify Game Files Integrity

If you’re failing to launch Modern Warfare 3 on either Steam or Battle.Net, the issue might be that you may have missing or corrupted game files. 

Therefore, users have to make sure that everything is installed properly by verifying the game file’s integrity. Follow our dedicated guide on verifying and repairing files to learn how to do this properly.

Close Unnecessary Background Applications and Services

One common issue that has constantly been affecting my Modern Warfare 3 gameplay and FPS is having applications like Chrome and Microsoft Edge running in the background, consuming a large portion of my system’s memory.

To ensure peak performance in Modern Warfare 3, I’ve recently developed a habit of always closing unnecessary browsers and software before diving into the game. We also have a detailed eXputer guide on terminating unnecessary applications to ensure your gaming experience is enhanced.

Disable Hardware Acceleration 

Disabling hardware acceleration has been a game changer for me, resulting in smoother gaming experiences across all Call Of Duty games, especially Modern Warfare 3. It shifts the application’s processing load to your CPU and RAM, which might seem efficient, but it can strain your resources during gaming.

Learn how to disable the hardware acceleration by reading our guide so you can improve your gameplay. 

Switch from NVIDIA’s DLSS to AMD’s FSR Settings

FSR is AMD’s Upscaler, which is similar to Nvidia’s DLSS, as it can increase performance while reconstructing the graphics quality to the selected resolution. For some players who own an Nvidia RTX card, DLSS might be causing problems in their games.

Hence, using AMD FSR may help you avoid any issues. If you decide to use AMD FSR on 1080p, we recommend not going below the “Ultra Quality” option.

  1. Firstly, you need to access the in-game settings by clicking the settings icon or by pressing the F3 button.
  2. Then, select Graphics.
  3. Now, switch to the Quality tab.
  4. Click the Upscaling / Sharpening section, then switch to AMD’s FSR 1.0.
  5. Lastly, click Apply Settings to save the changes you made.

Update GPU Drivers

I advise all Call Of Duty players to keep their GPU drivers updated, as it ensures that the hardware can support all the game components of MW3.

Most of the time, outdated drivers lead to performance issues, which has happened with me in the past, or even prevent Call Of Duty MW3 from running entirely, which can be a disappointing scenario.

Disable XMP

XMP enables memory modules to operate at speeds faster than the default settings, with the goal of boosting the overall performance of the system. XMP works great for several games, but it also causes problems for some, and MW3 is one of them.

I recommend disabling it to avoid any issues while playing Modern Warfare 3. Players across the Steam community recommend disabling XMP as well.

Here’s an easy way to disable XMP in the BIOS of your PC:

  1. First, restart your PC and access the BIOS menu by pressing Del, F2, F12, or Esc key during startup.
  2. Then, find settings related to overclocking or advanced settings in the BIOS menu.
  3. Locate the XMP settings and head over to the XMP Profile.
  4. Select the XMP option and turn it off by selecting “Disabled” or “Off”. The XMP profile will turn off.
  5. Save your current changes, exit the BIOS menu, and restart your PC.

Contact Call Of Duty Support

There might be some players who are still unable to figure out the cause and solution of this issue, so I recommend they head over to Activision’s MW3 support team and state their issue.

It’s only gonna be a matter of a few hours until the Activision support team receives your request and starts working on a possible solution for the issue. 

My Thoughts On the MW3 Error Code 0x887a0005

Slow gaming experiences and errors, especially during the early release of any high-end game, are likely to be experienced. The developers of Activision Modern Warfare 3 are not to be blamed directly, as they still release updates and patch notes further to resolve issues like these and many others.

I sincerely hope that the developers prioritize this issue and get it out of the way so the Call Of Duty community can have their freedom and fun. The purpose of this article is to guide you toward the best possible solutions on how to troubleshoot the Error Code 0x887a0005.
