There is no universal, officially documented Steam folder or button for manually clearing the Call of Duty shader cache. For shader problems, let the game finish shader preloading; use Steam’s file verification if you suspect damaged game files. Steam’s Clear Download Cache option clears Steam download data, not Call of Duty’s shader cache.
What to do if Call of Duty shader preloading is stuck
First, leave the game at the main menu and allow shader preloading to complete. Activision calls it “an important part of the first boot process” for Warzone PC. Activision warns that navigating away from the main menu stops preloading and can lead to performance issues.
Activision’s Modern Warfare PC troubleshooting guidance also says to let shader preloading finish before starting a game mode. That guidance is title-specific and older; do not assume every Call of Duty release behaves the same way.
Verify Call of Duty’s installed files in Steam
If you suspect missing or damaged game files, Steam’s verification tool checks the installation. This is not a shader-cache deletion, but it is an official troubleshooting option for the game’s installed files.

What Steam’s Clear Download Cache actually does
Use Steam > Settings > Downloads > Clear Download Cache for relevant Steam download or launch trouble—not as a Call of Duty shader-cache reset. Steam says clearing its download cache does not affect installed games, but you will need to sign in to Steam again afterward. The control clears locally cached download data; Steam does not describe it as clearing a game’s shader cache. Details are in Steam Support’s Clear download cache article.

Why you should not delete a guessed cache folder
The official guidance cited here does not identify a current Windows folder that applies to every Call of Duty version on Steam. Because the shader instructions available are tied to specific titles, a generic deletion path could target unrelated shader data or settings. Do not manually delete a folder unless support instructions for your exact game and version confirm the location and procedure.

| Action | What it affects | When it fits | What to expect |
|---|---|---|---|
| Wait for shader preloading | The game’s shader compilation/preloading process | Preloading is still running or shader-related performance trouble occurs | Keep the game at the main menu until preloading finishes; Warzone guidance warns leaving the menu interrupts it. |
| Verify game files | Call of Duty’s installed files | You suspect files are missing or damaged | Steam checks the installation; the process can take several minutes. |
| Clear Download Cache | Steam’s locally cached download data | Relevant Steam download or launch trouble | Installed games remain; sign in to Steam again afterward. This does not reset the game’s shader cache. |
Call of Duty is published by Activision, and Steam lists its Windows product with DirectX 12; those facts do not establish one shader-cache procedure for every title. See the Steam Call of Duty listing. Check the support instructions for your specific Call of Duty release before applying title-specific shader advice.
