What is DirectX Shader Cache?

Like other cache system, DirectX Shader Cache is a cache of DirectX shaders that are used to improve the performance of games and software. Since the games can use the shader cache instead of regenerating the game shaders each time they are needed, the time needed to render images and videos on the screen can be significantly reduced while loading the games.

Should I clear DirectX Shader Cache?

As you load and run games from time to time, the DirectX shader cache your computer accumulate will build up. This can take up a lot of storage space. If you are running out of storage space on your system drive, you may want to consider clearing the DirectX Shader Cache to free up some space.

Other than that, another common reason to clear the DirectX Shader Cache is when your games suddenly start to act strangely, causing lag and stuttering in game. The shader cache can sometimes get corrupted and causes issues when they are loaded. This is especially the case if you have recently installed a game patch or applied a major Windows Update.

Thus, clearing the DirectX Shader Cache often helps to solve these random game lagging and stuttering issues. After clearing the shader cache, the game will then be able to regenerate the shader cache from scratch.
