If you’re seeing Dev Error 6328 when trying to launch Call of Duty: Modern Warfare or when waiting in its multiplayer lobby, here are the fixes you can try to get back into gaming.
1. Try Performing Basic Repairs and Checks
The Dev Error 6328 can appear as a one-time system glitch. As such, restart your system and relaunch Modern Warfare to ensure this wasn’t a one-time fluke.
Also, an ongoing server outage or system-wide problem can trigger this error code. Before you dive into more complex solutions, visit the Call of Duty Modern Warfare server status page, and ensure all services are operational.
If the services are currently experiencing downtime, you can’t do much other than wait until they become operational again.
2. Run Call of Duty: Modern Warfare With DirectX 11
DirectX is a set of APIs in Windows that handle the graphical elements of software and games. Most of the latest games are compatible with multiple DirectX versions. For instance, Call of Duty: Modern Warfare is compatible with both DirectX 12 and 11.
But for some reason, DirectX 12 doesn’t work as well as DirectX 11 with Modern Warfare. In fact, running the game on DirectX 12 often results in various issues like Dev Error 6328.
As such, try running the game on DirectX 11 to get a more stable experience and eliminate the problem at hand. To do this, follow these steps:
Open Battle. net on your system. Click the Gear icon next to Call of Duty Modern Warfare and select Game Settings. Checkmark the Additional command line arguments box. Type -d3d11 inside the box and click the Done button.
Give the launcher a quick restart and check if you are still facing the problem.
3. Change Modern Warfare’s Priority Settings
Like any other triple-A title, Call of Duty Modern Warfare requires maximum CPU power to run without any issue. Unfortunately, other background-running applications hog available CPU power and leave the game with limited resources.
The solution, in this case, is to close all the unnecessary background running applications and then change Modern Warfare priority setting. Allocating higher priority to the game will ensure it gets higher system resource preference than before.
To change the priority settings of COD Modern Warfare, follow the below instructions:
Open the Task Manager, and select the Details tab. Right-click the Modern Warefare executable file and select Set Priority. Choose High from the list of available options. Click Change Priority to the confirmation box that appears.
Now, the game will keep running with high priority until you manually disable it.
4. Close All Origin’s Services
The error code can result from a conflict between Battle.net and Origin services. To solve this, you will have to close all the Origin services from the background.
Here’s how to do it.
Open the Task Manager by pressing the Ctrl + Shift + Esc hotkeys. In the Processes tab, right-click on all the Origin services and choose End task from the context menu. Switch to the Startup tab, right-click on Origin and choose Disable. This will ensure that Origin doesn’t start automatically on booting the system.
Next, restart the computer and check if you are still facing the problem. If yes, try the next solution on the list.
5. Increase the Virtual Memory for Your System’s RAM
You’ll most likely face the error code if your system runs out of memory. As a solution, you will have to increase the virtual memory allocation for RAM.
When the computer runs out of RAM, it uses virtual memory to offer a temporary expansion. It does so by using the hard drive to expand the RAM effectively. You can check out our virtual memory guide to know how to increase virtual memory on your computer.
6. Download the Latest Graphics Driver Update
Sometimes, you’ll face Dev Error 6328 because of a corrupt or outdated graphics driver. Fortunately, you can download the latest graphics driver update using the Device Manager to fix this. Here’s how to do it:
Press Win + X hotkeys and choose Device Manager. Extend the Display adapters list. Right-click on the driver and choose Update driver. Select Search automatically for drivers. Windows will now look for and download the latest graphics driver update.
If Windows doesn’t find anything you can visit the GPU’s manufacturer’s website to update the driver or use a free driver updater.
7. Delete the Blizzard Entertainment Folder
Like any other application, Battle.net also stores cache data to offer a faster service on your next visit to its platform. But with time, the cache files can get corrupted and cause various issues, including one in the discussion.
You’ll have to clear the Battle.net cache data to solve the issue. To do this, press Win + R hotkeys to open the Run dialogue box, type %ProgramData% and press Enter. Then, locate and right-click on the Blizzard Entertainment folder. Choose Delete from the context menu.
Next, give a quick restart to your system and check for the problem.
8. Reinstall Modern Warfare
If you’re still having issues playing the game, there’s likely something wrong with the game’s files. You’ll have to reinstall Call of Duty: Modern Warfare as a last resort.
Fortunately, reinstalling the game is one of those solutions that has helped many gamers fix the error code. But make sure you reinstall the game without any download pauses or errors.
