How to fix Modern Warfare 3 error code 0x0001338 bug
The following are some methods you can try to fix error code 0x00001338:
- Verify game files – Right-click on Call of Duty in your Steam library, hit Properties, and go to the Installed Files tab. Then click on the button that says “Verify integrity of game files” to go through a check. Sometimes files might have gotten corrupted during the download. This has helped some users who had this error during the MW3 beta.
- Uninstall and reinstall game – This has a low chance of working, but do try deleting the game and re-downloading it. It’s a hassle, but this could be the easy fix.
- Set GPU to run at a lower performance – Particularly if you have an AMD GPU, make sure that its FDR setting (FidelityFX Super Resolution) isn’t running on Ultra Performance. This error might be caused by your CPU being overloaded. For Nvidia GPUs, go to the Nvidia Control Panel, find the super resolution box under RTX video enhancement, and lower it to 1 or 2.
