How to fix the Call of Duty Modern Warfare 3 shaders error

The MW3 shaders preloading error occurs due to missing or corrupt shaders. It is likely that your game updated or that your game files somehow corrupted before you received this error. The solution is to replace those files, which is quite simple if you follow my steps:

  • Firstly, restart your PC
    • Let's address this first: restarting your PC may resolve any errors caused by your PC rather than the game.
  • Verify the integrity of your game files
    • Steam: Go into your Library, select the game, and then go into Properties. Click Local Files, and select verify file integrity. A scan will be run on your game, and any missing or corrupt files will be replaced.
    • Battlenet: Head into game settings on Battlenet, then click Scan and fix.

There is no way to avoid this error except by keeping your game updated at all times. I highly recommend staying up to date with Treyarch on X (formerly Twitter) to see if they have reported any known issues affecting all players. In that case, your best option is to wait for a hotfix and update your game as soon as it becomes available.
