Call of Duty: Modern Warfare and the popular Warzone battle royale share a number of error codes. One of them is dev error 5759, in which the game says DirectX encountered an unrecoverable error. This problem prevents either game from booting, and seems to be taking Warzone players by surprise. Here’s what to do if you encounter the Warzone dev error 5759 and what you can do about it.
Warzone Dev Error 5759 | DirectX encountered an unrecoverable error
The Modern Warfare and Warzone dev error 5759 gives clues about the problem alongside the error prompt: “DirectX encountered an unrecoverable error.” As this message implies, a problem was found in somewhere in the software used by your GPU. Sometimes the message continues to say things like “Your GPU driver version does not meet the minimum specification.” Other times it says your GPU is outright incompatible.

Dev error 5759 has been a nuisance since Modern Warfare first launched, and it has since carried over into Warzone. Unfortunately, the development team has yet to issue any kind of specific fix for it. However, there are a few workarounds that involve updating GPU drivers, GPU software, Windows, the game itself, or even disabling onboard video.
How to fix dev error 5759
Use the Scan and Repair tool
First things first: If you’ve encountered dev error 5759, you should try to repair the game. Through the Battle.net launcher, click on the listing for Call of Duty: Modern Warfare or Call of Duty: Warzone, click the Settings button, then choose Scan and Repair. With any luck, this will provide a quick fix for the problem.
Update your graphics card drivers
Assuming the Scan and Repair function does not allow you to launch the game, it’s time to start checking over your GPU and related software. The message saying DirectX encountered an unrecoverable error should lead you to your first tip: You need to update your GPU drivers.
Several users across various support forums have said that updating GPU drivers fixes dev error 5759. However, many report that the driver update must be performed manually. This process will differ depending on various graphics cards, but as a general rule, you can find the latest drivers by going to the manufacturer’s website and typing in the model of your GPU.
Download the newest drivers and install them. Afterward, restart your computer to make sure everything still works. At this point, it’s probably worth running the Scan and Repair tool once more just to be safe. If that doesn’t do it, it’s time to try something else.
Disable secondary displays and onboard video
Some users have encountered dev error 5759 and others when running Call of Duty games on systems with secondary monitors. Apparently this can cause problems, though no one is really sure why. Fortunately, the fix is simple: Unplug any secondary displays.

Alongside this, players also suggest disabling the onboard video on their computer’s motherboard. This shouldn’t be a problem for most, but it’s not exactly hard to address. Open the Windows device manager, then click the dropdown for Display adapters. If you see “Onboard” or “Integrated” listed, right click on it, then click Disable.
Update Windows
This last solution is a bit of a double-edged sword: Update your current version of Windows. While it’s generally smart to keep Windows up-to-date, having the latest version sometimes causes problems with game software. As such, updating Windows could fix dev error 5759, but it also could introduce other dev errors. With this fix, your mileage may vary.
The Call of Duty: Modern Warfare and Warzone dev error 5759 can be a chore to fix. Since it says DirectX encountered an unrecoverable error, the issue clearly has something to do with your GPU. Unfortunately, without any sort of first-party fix, your only choice is to update all your drivers and disable secondary displays. If these fixes don’t work, you should consider opening up a ticket with Activision support.
