Restart The PC
Let’s start off with something basic yet effective here. Restarting your Windows PC is one of the most subtle ways of approaching the dev error. We advise performing a reboot before getting into the more complicated fixes of the problem at hand. This is because doing so can potentially save you a lot of time and effort.
Click on the “Windows Start” menu and select the “Power” button to restart your PC. The next step is to choose “Restart” and wait for your PC to turn back on.
Try launching Modern Warfare once your PC is up and running again. Continue reading for more fixes if restarting your PC hasn’t solved the issue. We’ve got plenty more where that came from.
Clear Resource-Heavy Processes
The Call of Duty: Modern Warfare dev error 6070 can be surfacing because you’re not taking care of your PC too well. If you’re like most people who don’t take some time out for maintenance, issues like the latter are bound to pop up from time to time. Evaluate how many applications, system apps, programs, and other software are running on your device concurrently with the help of the Task Manager. If the figure you calculate cannot be classified as normal, then it’s definitely for the best that you start clearing resource-heavy processes right away.

As iterated earlier, the Task Manager will help you highly in this regard. All you have to do is launch it using the shortcut key combination of “Ctrl,” “Shift,” and “Esc” and that should do it. Once it’s opened up, check what your CPU and RAM utilization is. You need to be aware of these crucial system components before running anything graphics-intensive, let alone Modern Warfare. As soon as you’ve found something that’s not worth keeping, select it and then click on “End task.” That should do the trick for you.
Try playing the game again after clearing out unwanted applications from the Task Manager. If the dev error 6070 still hasn’t bitten the dust, keep on trying more fixes that we have laid out in this guide.
Check For All Relevant Updates
The only way to play Call of Duty: Modern Warfare is through the Battle.net launcher. It is Blizzard Entertainment’s very own platform for all of its games, including the relatively recent Call of Duty: Vanguard. Therefore, if you have a pending launcher update, prioritizing it before anything else could possibly fix the error 6070.
Once you’re done with that, it might pay off to check your operating system for updates as well. Windows is keen on regular updates, so check out the “Update and Security” section right away and see if you can get the system up to speed.
You will typically need to click on the “Check for updates” button in the “Windows Update” section to proceed. The following screenshot specifies where to click.
The last bit of this section relates to updating the game, of course. The official Call of Duty blog is a great way to stay up-to-date on all relevant information concerning Modern Warfare. If there’s a new patch coming out, update the game accordingly. Check your copy of the title in the Battle.net launcher to see if it requires any update for now.
If all related programs are up to the minute, try playing the game again to see if the dev error 6070 still persists. There’s a sizable chance that you’re going to play error-free now, but keep on reading for more fixes if the problem hasn’t ceased to exist just yet.
Update The Graphics Drivers
We thought it fit to separate the update of graphics drivers from the section above because this is one of the most critical fixes of the error 6070. This issue results from DirectX mainly, which is a system process that closely relates to your GPU. Checking your graphics drivers and verifying if they are lacking in some aspect can turn out to be worth your while.
It’s also important to note here that Modern Warfare has particular system requirements that the developer has clearly stated for players to fulfill. Out of all the other hardware that needs to be up to the mark, the GPU that Modern Warfare needs to run successfully should be the equivalent of NVIDIA GeForce GTX 670/GeForce GTX 1650 or Radeon HD 7950.
You will have to get an upgrade rather than an update if your graphics or video card doesn’t make the cut. However, if you already have the hardware required to run Modern Warfare, then, perhaps, an update just might do the trick here. The following steps are going to walk you through the process of updating the graphics drivers on a Windows PC.
1. The first step is to fire up the “Device Manager” system application on the PC. An easy way of doing that is by right-clicking the “Windows” icon in the top-left corner of the operating system’s interface, followed by clicking on the app in question. Alternatively, you can just search for it through the Windows Search bar as well. The following screenshot should illustrate the latter.
2. A separate window will launch as soon as you click on “Device Manager.” This is where you’ll be effortlessly able to get your graphics drivers up to speed. Click on the “Display adapters” entry to reveal your GPU. Right-click on the latter to expand the area. Once done, click on “Update driver” and you should be good to go until the next step.
3. A prompt will appear asking you, “How do you want to search for drivers?” Simply select the first option, which is, “Search automatically for drivers.” That way, the system will commence the hunt for any pending updates that your GPU hasn’t received yet. Your graphics drivers will be updated if Windows detects anything workable. After a brief moment, you’ll see that the update process will begin.
That’s about it for updating your graphics drivers on Windows 10. Having an up-to-date GPU is a sure-fire way of preventing the dev error 6070 from popping up, let alone fixing it. We recommend that you download dedicated software to optimize and take care of your graphics drivers on your device. That will make it easier for you to install updates whenever they are released from the developer’s end.
The software depends on the manufacturer whose GPU you have on the PC. For instance, you can install AMD Radeon Software to take good care of AMD graphics drivers.
On the other hand, you can opt for the Nvidia GeForce Experience application for Nvidia GPUs. Even if updating your graphics drivers to the latest version hasn’t solved the issue, or your drivers were updated in the first place, to begin with, keep on reading for more fixes to try. You’ll get there eventually with some luck and effort.
Optimize Nvidia GeForce Experience
Owning an Nvidia graphics card is nothing but exciting until the dedicated companion app that comes with it becomes the root cause of the dev error 6070. We’re talking about GeForce Experience that makes sure titles running on your PC remain to be buttery smooth. It takes up the big job of optimizing games, so they’re always suited to your hardware, but things can mess up here and there at times.
Therefore, if you have an Nvidia GPU and you’re currently unable to play Modern Warfare because of this vexing issue, it might be worth a shot to optimize the GeForce Experience application. We’re going to do just that in this section, so follow along the steps listed ahead and get possibly back to playing.
- The first step is to launch the Nvidia GeForce Experience companion application. You can do that effortlessly by pressing “Alt” and “Z” together. It is a shortcut key combination for opening the Experience app. Once done, click on the “Settings” icon that’s shaped like a cog.
2. Completing the last step will take you straight to the GeForce Experience companion app’s settings page. This is where you’ll see multiple options to click on, but to resolve the dev error 6070, we’re going to select “Highlights.” The following screenshot specifies where to click.
3. Once you’re at the “Highlights” section of the GeForce Experience application, you’ll see capture settings for Call of Duty: Modern Warfare 2019. There will be a toggle right beside the title. Click on it to disable the “Capture” feature for it that automatically takes screenshots and makes videos of your playthroughs.
4. Having the previous completed, return back to the main page of the settings and click on “Done” to finalize the process.
Congratulations on making it this far! You’ve successfully learned how to disable the “Highlights” feature for Modern Warfare and optimize the GeForce Experience companion application. Now seems like a good time to launch the game and verify whether this potential solution has resolved the Modern Warfare dev error 6070 for you.
If the issue still persists or you didn’t have an Nvidia GPU to begin with, continue reading for more tip-top solutions. Don’t lose hope just yet.
Add a Command In Blizzard’s Command Line Argument
The Battle.net launcher isn’t without its fair share of features and tools to facilitate players and help them have a smooth experience. One unique functionality introduced on the platform lets users modify the command line argument for each game. This makes it possible for instructions to be implemented in a title, such as changing its startup behavior and more.
The command that we’re going to add in the specified area will allow us to start Modern Warfare with DirectX11. You will have to compromise on premium-level graphics and visual effects, but at least you will be able to resolve the Call of Duty dev error 6070, so we fair the trade-off is pretty plausible. DirectX12 is notorious for stirring up tons of issues for players in not just Modern Warfare but in other titles as well. Therefore, let’s see if launching the latter without it helps us fix the issue.
The following steps are going to illustrate how you can add a command yourself in the “Command line argument” feature and replace DirectX12 with DirectX11.
- The first step is to fire up the Battle.net launcher on your Windows PC. That can be done seamlessly through the Windows Start menu. The following screenshot depicts how to complete this step.
2. The next step is to locate Call of Duty: Modern Warfare in your list of downloaded games. The area on the left of the main Battle.net interface will help you find the shooter. Right-click on Modern Warfare as soon as you’ve found it to reveal options related to it. Select “Game Settings” subsequently. Doing so should open another window on your end. You should now be all set to get to the next step.
3. You’ll now be transported directly to the “Game Settings” portion of the next window. This is where you’ll see the command line argument bar with a checkbox beside it for enabling the functionality. You know how it’ll go from here on out. Simply click on the box, turn the bar on, and type in the following command inside it. When you’re finished, click on “Done” near the bottom of this window to finalize the process.
Great going so far! You’ve successfully managed to incorporate an additional command-line argument in Modern Warfare using the steps given above. The Modern Warfare dev error 6070 should be out the door by now, so give the Battle.net launcher a good reboot and relaunch the title to see if it works fine now. If the issue continues to be a menace, keep on reading to try other solutions.
Disable Overclocking For Your GPU
Overclocking GPUs beyond their standard capability is a common practice in PC gaming. Doing so makes it possible to push the graphics card ahead of its limit, put more pressure on it, and compel it to perform better for your games. Overclocking is a fairly safe procedure since most modern-day GPUs are built to handle themselves quite profoundly, so you should be good with a substantial performance increase that way.
However, what’s not good is this feature giving rise to the tedious error. Some players who had overclocking enabled on their graphics card could solve this DirectX problem by simply disabling the latter. By sacrificing performance over playability, users could get their copy of Modern Warfare to run properly again.
Of course, this means that you’re pushing your GPU near its absolute breaking limit if mere overclocking does not let Modern Warfare run in peace. You can confirm whether this is the case or not by disabling this performance-boosting functionality on your Windows PC right away.
GPU TWEAK III by Asus is a commendable program that can help you turn off overclocking momentarily for verification purposes. It features manual controls that can turn down the performance at will, so you should be good to go with the software.
Download it from the official website to get started. The user interface of the program is intuitive and easy to grasp, so there shouldn’t be an awful lot of difficulty in disabling your GPU’s overclocking.
If you’ve managed to turn it off, try rerunning Modern Warfare to see if the error is still causing the game to crash. If you can’t play the game even now, continue reading for more solutions.
Try Using the Fullscreen Borderless Display Mode
This might come off as a tad bit peculiar, but a niche group of players has reported fixing the Modern Warfare dev error issue by using the “Fullscreen Borderless” display mode from the in-game settings. There is no guarantee that doing this will solve the issue for you, but the least we can say is that it’s worth a try.
All you have to do for this potential fix is to go into the game’s settings, click on the “Display” tab, and choose “Fullscreen Borderless” as the “Display Mode.” The following screenshot should illustrate this step.
In addition to this, it’s also worth keeping your “Sync Every Frame” or V-Sync setting enabled for Modern Warfare. This is an important optimization technique that takes up the hefty task of matching the refresh rate of the monitor and the frame rate of the game that you have.
After tweaking these parameters, restart the game and try playing it again to see if the Call of Duty dev error 6070 has ceased to exit or not. You only have one last potential fix, and we’re afraid that the game is still giving you issues.
Reinstall the Launcher
Reinstalling the Battle.net launcher is also a potential fix of the Modern Warfare Dev Error 6178, which also happens to be a DirectX issue. It appears that you have only this approach left to pursue if all else has failed to work. Make sure that you uninstall Modern Warfare as well before reinstalling the launcher for the best results.
Simply head over to the “Add or remove programs” section by looking it up in your Windows Search bar. Once you’re there, scroll down the list of installed applications until you find Battle.net. Click on it to reveal the uninstall button and then follow it up by selecting the latter. Doing so should rid the program off from the system promptly.
You can grab the Battle.net launcher again from the official website of Blizzard Entertainment. Use this direct link for a head start. Install the platform on your PC and download the game again. Hopefully, doing so should fix the dev error 6070, so it no longer stays a bother for you. All of this is nothing but an exceedingly time-consuming process, but it’s, unfortunately, the only way of solving the dev error issue when doing nothing else pays off.
Call of Duty: Modern Warfare is one of the best first-person shooters in the industry that’s prone to run into its fair share of errors, with the dev error being duly one of them. Fret not, though, because the fixes listed above in this guide are bound to get your copy of the game error-free in one way or the other.
