CoD MW3 and Warzone: How to fix development error 5433


    Another seasonal CoD update, another error code. For CoD Season 3 Reloaded, players are receiving dev error 5433, which appears to be the result of corrupted or overloaded cache data. In this guide, we will explain how to resolve CoD Dev error 5433.

    How to fix dev error 5433 in CoD MW3 and Warzone

    Change allocated texture cache size

    To fix the error, go to the “On-Demand Texture Streaming” option within the Graphics tab of the Settings menu and change the “Allocated Texture Cache Size” to “Small.”

    By doing this, you should end up resolving the issue that is preventing you from playing and being able to see the new content in this season update.

    Restart your PC or console

    If this doesn’t work, you can always try restarting your console. But you don’t want to just turn it off and on again, you’ll want to reboot the system properly. To do this, unplug the power cable from your PS5 and wait a few seconds before plugging it back in and turning it on. This should clear some cached data and hopefully allow you to avoid development error 5433.

    Xbox players should hold down the Xbox button on their controller and select the “Restart Console” issue. This is a very convenient way to reset your console and often solves many technical problems with crashing or crashing games, or even with the console itself.

    For PC gamers, you’ll want to close Steam completely and then shut down and restart your PC.

    With any luck, this should solve the problem.

    PC only: Verify integrity of game files

    If you are playing on Steam, you can also make sure that none of the downloaded game files are corrupted. To do this, right-click on MW3 in your library and select the Properties option. Now go to “Installed Files” and select the “Verify integrity of game files” option.

    It’s worth noting that this takes quite a while to complete, but if it saves you from re-downloading the full game then it’s worth it.

    Reinstall Modern Warfare 3 / Warzone

    If all else fails, you’ll need to go ahead and uninstall and redownload the game. It’s the least ideal solution of all, but at least that way you know there can’t be corrupt data from the update preventing you from playing once it’s fully reinstalled.
