The Dev 5759 error has been a nuisance since the launch of Modern Warfare and has since been carried over to Warzone. Unfortunately, the development team hasn't posted any kind of specific fixes for this yet. However, there are some workarounds that involve updating the GPU drivers, GPU software, Windows, the game itself, or even disabling integrated video.

How to fix dev 5759

Use the scan and repair tool

First of all: if you are encountering dev error 5759, you should try to repair the game. Via the launcher, click the Call of Duty: Modern Warfare or Call of Duty: Warzone listing, click the Settings button, then choose Scan and Repair. With any luck, this will provide a quick fix to the problem.

Update your graphics card drivers

Assuming the scan and repair feature doesn't allow you to launch the game, it's time to start checking your GPU and related software. The message saying DirectX encountered a fatal error should lead to your first suggestion: you need to update your GPU drivers.

Several users in various support forums have stated that updating the GPU drivers fixes the dev 5759 error. However, many report that updating the driver must be done manually. This process will differ between different graphics cards, but as a general rule, you can find the latest drivers by going to the manufacturer's website and typing in your GPU model.

Download the latest drivers and install them. Next, restart your computer to make sure everything is still working. At this point, it's probably worth running the scan and repair tool again just to be safe. If it doesn't, it's time to try something else.

Disable secondary displays and integrated video

Some users encountered dev error 5759 and others when running Call of Duty games on systems with secondary monitors. Apparently this can cause problems, although no one is really sure why. Fortunately, the fix is ​​simple: unplug any secondary displays.

Apart from that, gamers also suggest disabling onboard video on their computer motherboard. This shouldn't be a problem for the most part, but it's not exactly difficult to deal with. Open Windows Device Manager, then click the drop-down menu for Display adapters. If you see "Onboard" or "Integrated" in the list, right-click on it, then click Disable.

Update Windows

The latter 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 the game software. Therefore, the Windows update might fix the dev error 5759, but it might also introduce other dev errors. With this fix, your mileage may vary.

Call of Duty: Modern Warfare and Warzone dev error 5759 can be a job to fix. Since it claims DirectX encountered a fatal error, the problem clearly has to do with your GPU. Unfortunately, without any kind of first-party fixes, the only choice is to update all drivers and disable secondary displays. If these fixes don't work, you should consider opening a ticket with Activision Support.
