If Modern Warfare 3 is installing shaders every time you play, it can be irritating. How fast shaders install depends on your PC. So, this problem can be either a minor annoyance for those with high-end hardware or game-breaking for someone with a low-end PC. Unfortunately, you won’t get an error message if you have to install shaders each time you play, as the game doesn’t detect anything wrong.
Is there a fix for shaders installing every time I play Modern Warfare 3?
If your shaders install each time you play Modern Warfare 3, it’s a bug. This issue has persisted since the first Modern Warfare reboot launched in 2019, and Activision has yet to quite fix it in the years since.
If MW3 installs shaders each time you play, it’s usually due to corrupted tiles. As such, there are a few methods you can try to fix the issue:
- Verify game files
- Uninstall and reinstall the game
Verify game files

- Select the game name in the left column and right-click on it.

Uninstall and reinstall the game
If verifying your Modern Warfare 3 files doesn’t work. Then, you may need to uninstall and reinstall the game. Unfortunately, due to the size of MW3, this is an arduous task for many players. If you have slow internet or a data cap, you may want to contact Activision support and get one-on-one help with fixing the issue before you go through the trouble of reinstalling.
