The Dev Error 6065 can be easily called one of the most annoying and widely occurring frequent errors found among the Modern Warfare Game community.

It does not matter which Modern Warfare game forum community you are visiting. This one Dev Error is always been a hot topic everywhere and for quite some time now.

Thus, today, I have decided to take this issue at hand and list out all of the possible solutions out there to fix this tiresome error once and for all. 

[Troubleshoot] Dev Error 6065 “DirectX Encountered An Unrecoverable Error”

Fixing the Dev Error 6065 in Modern Warfare is rather very simple and easy for most parts, until and unless your PC has some really crucial hardware missing required to run the game.

Generally, fixes like Editing Config filesre-installing the gamedeleting a few player folders or files, and scanning – repairing game files do the trick just fine.

However, if things aren’t fixed with these easy remedies, then more in-depth solutions like Disabling G-syncRe-installing GPU drivers, and increasing VRAM performance should be tried to surely and certainly get the job done.

Below, I have tried to explain in detail all the methods and solutions to fix the Dev Error 6065, as well as other such similar Dev Errors which may arise from this particular game.

Causes of Dev Error 6065 Code Problem Issue 

Before we head to the part where we look and try out all the various methods and solutions to fix the Dev Error 6065 issue.

It would be a good idea for us to first understand the main causes of such errors in order to tackle the issue more accurately and properly.

However, if you already know the reasons for such errors to occur, then you can straight away head to the solutions.

But still, I would anyhow advise that you understand the causes first as that will enable you to understand what may be wrong with the setup and thus deal with it properly without wasting much valuable time of yours. 

1. External program interface

At times external applications may hamper the workflow of a particular program which may result in such an error to occur.

In such cases, you will need to keep in mind which recent applications you had installed onto your device prior to when the issue showed up.

2. Corrupted program files

Many times, software applications abruptly stop or halt due to corrupted files which may be a result of unknown manipulation or damage of files inside the game or application’s source files.  

3. Outdated graphics drivers

Drivers play a very vital role in smoothly running an application or game on your PC.

Also, it is equally important that such drivers are always up to date and regularly updated to meet the requirements of new applications which make their way in correspondence to new specifications. 

4. Outdated PC OS

If you are already a veteran gamer, then this may already be a very obvious and known reason to why an application or game may show a ‘dev error’.

It is very important that you check beforehand what type of OS or version of OS supports the game.

If the OS you are trying to install the game does not support it, then such an error showing up is inevitable.

5. PC Hardware requirements

Similar to what we had seen earlier in the case of the type of OS and version a game supports.

PC Hardware specifications play a very crucial role in deciding whether a game would run smoothly or give you a hard time with such errors showing up every now and then.

Hence, once again, it is extremely important that you first check the system requirements needed to run the game before installing it so that such errors do not pop up.

Similar types of Dev Error 6065 Code Problem 

Besides the most common 6065 Dev Error, there are other Development Errors too, that may arise from time to time from Modern Warfare.

Although these errors may arise due to various other causes.

The overall solutions or methods to solve these issues are pretty much the same and common which I’ll be describing below Under “The top x methods to fix Dev Error 6065 for Modern Warfare”.

Finally, after understanding why such errors may occur as well as the various types of dev errors out there.

Next, I believe we can straight away head to solving these issues by implementing either one or all of the various methods mentioned below. 

Now, here you have to understand that since such errors are mostly general in nature and may arise due to any of the above causes.

The solutions too similarly need to be general i.e. either a single method may be enough to solve the issue, or you will most possibly need to try it all one after the other to fix the error.

Hence, depending upon how you manage to go by applying the solutions through trial and error, the error should be fixed. 

  • Update Drivers
  • Re-Installing GPU Drivers
  • Editing The App Config Files
  • Deleting Warfare Data Folder
  • Repair Game Files Using The Blizzard App
  • Tweaking Screen Optimization
  • Deleting Blizzard Battle.Net Files
  • Increasing VRAM Ability
  • Disabling G-Sync
  • Lowering Graphics Settings For Modern Warfare
  • Re-Installing The Game

1. Update drivers

This method is one of the easiest and most convenient of all.

At times, when your system or PC drivers are not up to date, such errors may regularly show up on your screen whenever you run games like Modern Warfare on your system.

Hence, the very first thing you should check and update are your PC drivers.

You can do this by simply going to your Device Manager option and updating drivers as required by right-clicking on the drivers you want to update and selecting update.

2. Re-installing GPU Drivers

At times, just re-installing your PC’s GPU drivers may do the trick.

Although you might have updated your GPU drivers as well while updating drivers on your system, as mentioned above, still such an issue may persist and pop up whenever you try running the game.

In such cases, you will once again need to head to your PC’s Device Manager option.

Then, by selecting and right-clicking on the Display Adapter option, choose to Uninstall the driver.

Once you are done with that, simply Restart your system and let Windows automatically reinstall the driver back onto your PC. 

3. Editing the app Config files

Config files play a very vital role in running a game smoothly, and if somehow these config files are unable to register the correct graphic card information or pick up the wrong data.

Then in such cases, such Dev errors are bound to show up on your screen. 

Let us have a look at the following steps in detail to how you can make changes to the game’s config files in order to fix the problem:

  • If you are already running the game, then close it by going to your Task Manager and then closing it from there.
  • Next, head to the games folder Call of Duty Modern Warfare and click on the Player folder and open it.
  • Once you are inside the Player Folder, search for the file name config.cfg and open it on Notepad.
  • Then go through the lines one after the other and try to locate where your Graphics card name is present.
  • If the name is not the same as the one you are using on your machine, then simply change and edit the name to the one you have. Then click on Save and close the screen.
  • Lastly, restart your PC once and then try running the game.

4. Deleting Warfare Data Folder

When you go on randomly and simultaneously creating game profiles on your game, there are times when the game might create profiles with different game configurations which may in the long run, create conflict within the game files itself during the launch process. 

This, too can be fixed by going to the game folder and tweaking a few things here and there as follows:

  • Once again, similar to the first step shown in the previous method, go to Task Manager and close the game from there.
  • Next, go to Documents and locate the Call of Duty Modern Warfare folder. 
  • Click on the Call of Duty Modern Warfare folder and then inside it if you see folders name for e.g. players or players2 or players3, then move them safely to a different folder for backup.
  • Once you have moved the player files as mentioned above. Next, delete the files from the actual game folder location from where you had moved the files and then Restart your PC. 
  • After Restarting your PC, now try launching the game again. 

5. Repair Game Files using the Blizzard app

The Blizzard app can come really handy at times in resolving such issues without having to deal with hassles like finding the errors manually.

This app can manage to do all that quite automatically and efficiently.

All you need to do is scan the device for any abnormalities in the game files and repair them with its help.

Let us look at how you can use the Blizzard app to resolve the 6065 Dev Error as described below:

  • Go to the Blizzard app installed on your device and launch it.
  • In the left pan, locate Call of Duty Modern Warfare and click on it.
  • Then on the right pane under the game’s page, click on the Options tab, and from the drop-down menu, select the Scan and Repair option.
  • Now, just like you would carry out a Scan and Repair function, click on the Begin Scan button and let the scanning and repairing of missing and corrupted files automatically take place.
  • Lastly, Restart your PC once and then try launching the game.  

6. Tweaking Screen Optimization

Tweaking your screen optimization options can also work wonders at times.

All you need to do for this is simply follow the instructions as given below:

  • First and foremost, just like you had been doing so far. Close the game if running by going to Task Manager and shutting it out from there.
  • Then, head to Blizzard’s Battle.net client app, and similar to as shown in the previous method right click on the Call of Duty Modern Warfare game tab.
  • Next, on the right pane menu, click and select the Options menu, and from the drop-down menu, choose the Show in Explorer option.
  • Now, once you are in the game file, look out for the exe game file and by right-clicking on it go to Properties.
  • Under the Properties screen, head and click on the Compatibility tab and check the Disable Full-Screen Optimizations option and click on Apply changes. 
  • Lastly, press on the OK button, and after restarting your PC, try launching the game.

7. Deleting Blizzard Battle.net Files

If you have Blizzard’s Battle.net app on your device, then you might try deleting it in order to solve the dev error 6065 as well.

Now, here although the error might or might not have occurred due to the following app. Still, there is no harm in uninstalling the app, to be sure.

All you need to do here is search for the Battle.net app with the help of the Windows Search option, and once you find it, just right click on it and click on the Uninstall option from the drop-down menu.

Follow the prompted instructions to uninstall the program and then try launching the game once more.

8. Increasing VRAM ability

At times, when no other methods work, you will need to get a little technical.

Thus, for the following method, you will need to work out with your system’s BIOS to try to solve the issue. Let us have a look at how to get it done below:

  • Firstly, you need to go to your Window’s Settings option in your Start Menu.
  • Next, under the System option, click on Display and then head to Advanced Display Settings.
  • Under Advanced Display Settings, go and click on the Display adapter properties link, which you can find under Related settings.
  • Then once you are prompted with the properties tab, go to the Adapter option and check the value of the Total Available Graphics Memory. Once you note it down, click on the OK button and close the tab.
  • After all, this is done, next you will need to Restart your PC and head to your BIOS menu. Now, how you access your BIOS menu may differ from system to system and brand to brand. You can search for how to access BIOS for your respective systems easily from the net.
  • Once you are in your BIOS menu, try locating your Video Settings or Graphics Settings. This, too may vary from machine to machine.
  • However, once you do gain access to your Video Or Graphics Settings, click on Pre-Allocated VRAM or Internal Graphics Memory Size and change the default memory allocated to your desired value i.e. 512M and save the changes.
  • Now Restart your PC once again and try launching the game.

9. Disabling G-Sync

If you are running the game on Windows 10, then you have a really powerful tool at your disposal which has been designed and prepared to tackle such issues only. 

With the G-Sync tool, users are able to optimize the game according to their choices and the system’s preference so that no such issue can occur in the first place. You can make use of the G-Sync tool as follows:

  • First and foremost, with the help of the Task Manager, close the game completely.
  • Next, if you are an NVIDIA user, go to your NVIDIA control panel and select on the Display option. 
  • Under the Display drop-down menu, click on the Setup G-Sync option, and then under the Setup G-Sync window on the right pane, uncheck the box for Enable G-Sync to disable it.
  • Once all that is done, click on the Apply button, restart your computer and launch the game.

10. Lowering graphics settings for Modern Warfare

This happens pretty often when your game is running at the maximum graphics resolutions, and the system is at a threshold point, such errors may occur pretty often.

To deal with this, all you need to do is try to compromise a little on your graphics quality and optimize your graphics settings to the point where your system runs smoothly, and the game works perfectly.

In order to do that, you can simply follow the values for the setting I have listed below or even try out values which best suit you and your system.

  • Under your Modern Warfare game’s Settings option, go to the Graphics tab.
  • Next, head on to the Display option and choose and change the value to 1920 x 1080.
  • Under Render Resolution, change the value down to 100.
  • Disable Sync Every Frame and NVIDIA Highlights as well.
  • Then disable the following: Cache Spt ShadowsCache Sun ShadowsRay TracingAnti-aliasingWorld Motion BlurWeapon Motion BlurTessellation, and Crossplay.
  • Then set the following options to low: Shadow Map ResolutionTexture ResolutionParticle Quality, and Particle Lighting.
  • Finally, enable the Server Latency option and save your settings.
  • Now, close and relaunch your game and see if the error still persists.

11. Re-installing the Game

Finally, if nothing seems to work, then you might try uninstalling the game and then reinstalling it once again. 

Sometimes during installation, certain files may get corrupted or left out which then results in such errors to pop up while running the game.

Although, the chances of this happening may be very small.

Still, it is not something which is impossible.

Hence, if you feel that during installing the game onto your device, the process may have been hampered due to some other third-party apps working in the background, then reinstalling the game is definitely something you should give a try.

Conclusion

As I had already mentioned at the very beginning. Depending upon what the cause may be for such an error to occur, the solutions listed above may work at one go or may need some trial and error.

Fact that we cannot specifically detect what the precise cause of the error may be, trying out each method and solution to find the one that works best is the only option.

However, even after trying all the above mentioned solutions, the error still remains.

Then there is probably something wrong with the hardware of your device, and you may need to handle the job physically by checking your cards, terminals, and hardware components.
