On-Demand Texture Streaming enables high-quality textures to be downloaded from the internet while playing the game, enhancing surface color detail. However, excessive allocation of texture cache size can exceed data limits, resulting in Dev Error 5433. Follow these steps to modify this option:

Launch Call of Duty HQ.
Head to Game Settings.
Select Graphics, then Quality.
Scroll down to find the On-Demand Texture Streaming option.
For PC: Set the Allocated Texture Cache Size to 32GB or below.
For console: Set the Allocated Texture Cache Size to Small.

This fix is highly effective and should resolve the error. However, if you still encounter the issue, there are alternative solutions below.

2) Repair game files

Corrupted files within the game may trigger Dev Error 5433. Repairing the game could resolve this issue. Follow these steps to do so:

For Steam users:

Launch Steam
Select Library
Right-click Call of Duty
Select Properties
Head to the Installed Files section
Click on Verify integrity of game files

For Battle.net users:

Launch Battle.net
Select Call of Duty
Click the settings option next to the Play button
Choose Scan and Repair from the drop-down menu

3) Lower your graphics settings

Consider adjusting your graphics settings to a lower resolution, as high-resolution textures may conflict with the graphics driver, potentially causing this error. Ensure you have the latest graphics drivers installed before proceeding. Start by selecting the minimum settings; if the issue is resolved, you can increase the quality settings again.

To change your graphics setting, follow these steps:

Launch Call of Duty HQ

4) Restart your system

Whether you're on a PC or console, the most basic troubleshooting step is to restart your device. This may potentially resolve the issue.

5) Check server status

If you encounter errors, it's crucial to check the Call of Duty server status on the Activision online service page. If the servers are down, you'll need to wait until they're back online before starting the game.
