Flushing DirectX Shader Cache
On Windows, DirectX Shader is an optimization feature for storing pre-compiled versions of special instructions, known as shaders.
Shaders are small programs understood by the graphics card that control various graphical effects.
Compiling shaders can be time-consuming, and using a cache helps optimize performance by providing easier and faster access to pre-compiled versions.
The decision to clear the cache will depend on you. However, below are some reasons why you may want to do so.
To resolve performance issues – A cleared DirectX Shader cache may resolve some performance issues, including graphical glitches and stuttering.
Freeing up disk space – Even though the cache may not take up much space, clearing it will still free up some extra space on your computer.
To update the cache – If you have just updated your graphics card or installed new games, you may clear the DirectX Shader cache to fill it with new information.
Note: Clearing the cache is not something you must do often. It is mainly a troubleshooting step when you face some graphical issues.
This procedure will not negatively affect your system. This is because the cache is isolated storage with no permanent information.
You cannot disable or prevent the creation of the DirectX Shader Cache. Windows 11 has no official way of disabling this optimization feature.
Ccleaner provides an option to flush the DirectX Shader Cache.
To flush Shader Cache Using Disk Cleanup
1. Open Start Menu, type cleanup in the search bar, click Disk Cleanup to open it.

3. Tick the DirectX Shader cache option and click OK.
Note: Though this is meant to flush DSC, it could be a good idea to check every listed item.
