Is It Safe to Delete the DirectX Shader Cache?
Asked by

A game troubleshooting guide suggested clearing the DirectX Shader Cache. Is deleting it harmless, or could it cause lasting problems? Will games simply rebuild their shaders the next time they launch, and could clearing the cache lead to permanent performance loss?
Answers
Most games will recreate the shader cache automatically when they launch. Clearing it can sometimes help with graphics-related issues, but the first run afterward may be less smooth while everything is compiled again.

There’s nothing permanent being deleted here. DirectX shader caches are generated files used to speed up rendering, not essential system components. Removing them shouldn’t cause lasting performance problems; at worst, you may experience temporary stuttering or longer shader-building times until the cache is recreated.
QuietMarble28: Exactly. The shaders are temporary files created for the games and hardware, so they can be generated again whenever the game needs them.

It’s generally safe to clear. The cache is temporary, so games and graphics drivers will rebuild the shaders as needed. Until that happens, you might notice longer loading times or occasional stutters, especially if the game starts compiling shaders while you’re already playing.

MellowCedar42: So can I just delete the contents of the shader-cache folder in AppData, or is it better to use Windows Disk Cleanup?
