Causes of COD Warzone dev error 5759

There are several known reasons for dev error 5759. Let’s discuss each of possible causes in the list below.

Random game glitch.

Bugs and glitches are part and parcel of both old and new games. Even well-built apps and games from world-class developers have bugs, and some of them are even game-breaking. Although Warzone is already a polished product during release, it requires constant updates to fix errors and glitches from time to time.

If you only experience the dev error 5759 once or twice, it may be due to a randomly triggered bug that develops out of nowhere. 

Some bugs like the ones related to DirectX may also be caused by a unique problem in your device and has nothing to do with how the game was coded. There are several known “DirectX encountered an unrecoverable” errors for the Call Of Duty titles over the years and some of them are caused by factors associated with Windows or certain hardware components or graphics card.

Damaged game data.

Game files may sometimes become corrupt, which can then lead to all sorts of error codes such as the Warzone DirectX dev error 5759. The most common reason for file corruption is when the “saving” process is interrupted, like when a PC or console loses power. At other times, game files may be damaged if an update installation is also disrupted when the device shuts down in the middle of the process.

If you started receiving the dev error 5759 after your PC crashed or stopped working in the middle of an installation or “saving,” you may be dealing with bad game data.

Outdated software environment.

If your computer’s software environment is running outdated drivers and apps, it might also lead to certain game errors. It is important that your video card receives regular updates in order for it to work with new games.

The same is true for your PC’s Operating System. Windows, just like apps and drivers, must be constantly updated so it can deal with new changes to the programs like video games you’re running.

Interference from third party software.
