by | Last updated:

Many players diving into Call of Duty: Modern Warfare for the first time or after an update often encounter a frustrating issue — shader installation getting stuck. Whether it’s stuck at 0%, 24%, or 100%, this problem can hinder gameplay quality or even prevent access to certain features like multiplayer or Warzone. Fortunately, there are several proven methods to resolve this game-halting issue and get back to uninterrupted action.

Shaders are essential for the game’s graphics, affecting textures, lighting, and performance. When they fail to install properly, it can cause graphical anomalies or long wait times when launching the game. Here’s how to identify, fix, and prevent shader installation from getting stuck in COD Modern Warfare.

Why Shader Installation Gets Stuck

The shader installation process can freeze due to:

  • Corrupt game files
  • Network issues
  • Pending game updates
  • Outdated GPU drivers
  • Launcher bugs from Battle.net or Steam

Before diving into advanced fixes, check for any pending updates and restart your game and PC. If the problem persists, try the following solutions.

Top Fixes for Shader Installation Stuck in COD Modern Warfare

1. Manually Cancel and Reinstall Shaders

This solution works in many cases. Follow these steps:

  1. Open Call of Duty: Modern Warfare.
  2. Head to Options > Graphics.
  3. Scroll to find the Shader Preloading section.
  4. Click Cancel Installation.
  5. Restart the game and allow shaders to reinstall from scratch.

Ensure you give enough time for the new installation to complete without switching modes or exiting the game prematurely.

2. Clear the Shader Cache

Another effective strategy involves deleting your shader cache manually. To do this:

  1. Close COD and Battle.net completely.
  2. Navigate to the game’s directory (usually in the Documents or Program Files folder).
  3. Locate the folders named “Blizzard Entertainment” or relevant to COD.
  4. Delete the “ShaderCache” folders.

Restart the game, and the shimmer-preloading process should reset and continue normally.

3. Update Graphics Drivers

Outdated GPU drivers can cause compatibility issues with shaders. Visit your GPU manufacturer’s website — NVIDIA, AMD, or Intel — to download the latest driver versions. After installation:

  • Restart your PC
  • Re-launch COD and monitor shader processing
