Solution 2: Update Graphics Card Driver

An outdated or corrupt graphics card driver is a common cause of many video game problems, and since it passes messages between the operating system and the hardware, your game will always have problems when it fails, including Warzone dev error 6634 and error 6065. To fix this problem, you can try updating the graphics card driver. There are two easy ways to update drivers.

Manual way

Right-click the Start icon > Choose Device Manager > Find out your graphics card on the Display adapters > Right-click the graphics card you choose to update and then choose Update driver.

However, this method is only available to deal with some basic and general updates for your graphics card. If you want to make sure error 6634 does not relate to the graphics card, you’d better go to the official site of your graphics card or try the next professional way.

Professional way

Driver Booster can be a good gaming tool to help you get the latest graphics driver automatically on your PC. As a professional driver finder and downloader tool, it can detect all the missing and outdated hardware drivers for your computer and update them to the latest version.

In addition to hardware drivers, driver booster offers some more direct help for gaming users. It scans for the components such as Open AL, .Net Framework for your game and downloads them directly. In addition, its game mode can help you speed up the game.

After that, reboot your computer and running Warzone again.

Solution 3: Repair Corrupted Game Files

Corrupted and missing game files can also adversely affect Call of Duty: Warzone. Since game files control gameplay and how your system reads programs, you will likely see error 6634 if any game files are missing or corrupted. Error 6634 may indicate an integrity issue with your game files.

So instead of reinstalling the entire game, you can start by scanning and repairing the corrupted game files. If you don’t know how to do this, just follow the instructions below:

Step 1: Launch

Step 2: Go to the left menu and choose Call of Duty: MW from the PARTNER GAMES section.

Step 3: Click on Options and next choose Scan and Repair.

Step 4: Click on Begin Scan, and wait patiently for the process to end.

Step 5: After completion, try restarting the game.

Solution 4: Release space of RAM and VRAM

As you can see from Warzone’s minimum system requirements, it requires RAM of 8 GB, so it is a game that requires a lot of RAM and VRAM to run smoothly. So Warzone may have memory leaks in some systems, which means it starts using more RAM or VRAM while you keep it running.

So if you’re getting dev error 6634 or dev error 5763, it’s probably because your RAM or VRAM is clogged. The most efficient way to free up VRAM and RAM is to restart the game. This action will reset system resource usage, or you can restart Warzone game after each match. By doing this, your game memory usage is automatically reset.

Or you can also download and install a gaming program like Smart Game Booster to release RAM and VRAM to optimize your PC.

Solution 5: Check Windows Updates

If Warzone crashes again with the same error 6634 and a window pops-up on your screen showing the latest update for Microsoft Windows, which includes the latest security patches, then you have to try to update your system.

Because Windows update is a critical component and resource to keep your operating system running smoothly. Call of Duty: Warzone requires most of these components to function properly.

If your system is not updated, this game may experience dev error 6634 because your computer is missing some updated operating system components.

Listed below are some of the steps you can use to manually check for Windows updates.

Steps: Right-click the Start icon > Choose System > Scroll down on the left panel to find out Windows Update > Click Check for Update on the right panel.

After installing all Windows updates, restart your PC and check if the error goes away. Make sure to update your system frequently to avoid encountering such issues again.

Solution 6: Reinstall all Shaders

Shaders, a feature available in Warzone settings, are a type of program primarily used to render different pixels. Occasionally, they can malfunction and interfere with gameplay, resulting in dev error 6634.

Some players have reported that reinstalling shaders could be a potential solution to dev error 6634, so you can try the same and see if that helps.

Please follow the given steps.

Step 1: Run Warfare and then go to Options.

Step 2: Go to the Graphics tab and choose Restart Shaders Installation.

Step 3: Hit the Restart option to proceed further.

Step 4: Wait patiently until the process completes.

Step 5: After completion, open the game and check for errors.

Solution 7: Change Your Skins, Loadouts, And Operators

When dev error 6634 first appeared in Warzone, most players who reported the error had one thing in common: loadouts, operators, and skins seem to cause dev error 6634. To address this error, some players said the issue could be easily fixed by changing Modern Warfare’s configuration.

For example, if you’re using an operator or loadout, change it to Modern Warfare and then check the results. At the same time, you can also delete any skins you have activated and check if that solves the problem.

Solution 8: Check your Antivirus Programs

The antivirus programs can also affect gaming in many ways. One way is that it slows down your computer, which affects your gaming performance. Another way is that it may interfere with certain game files or functions, causing problems in the game.

Finally, some antivirus software may also block certain gaming sites or features, making it difficult to access or play certain games. This interference may be the reason why COD: Warzone keeps showing error 6634 and shutting down.

So it’s a good idea to add the game as an exception or exclusion in your antivirus programs. Doing this prevents the program from interfering with Warzone in the future.

Solution 9: Uninstall and Reinstall Warzone

If none of the methods above worked in your case, and you’re still getting dev error 6634 when running Warzone, you should be able to avoid the problem entirely by uninstalling the game and strictly reinstalling Warzone.

Of course, there is a troubleshooting method that most Warzone players don’t want to try unless it’s a last resort because it takes a long time to download Warzone. But it is a general troubleshooting method that can effectively resolve different errors.

So this post aims to fix your dev error 6634 issue in Warzone. Hopefully, it will help you fix this error and get back to Warzone and run it with ease again.
