This feature saves compiled shaders to your storage so they don't need to be rebuilt every time you play. You can enable this under Emulation > Configure > Graphics > Advanced .
: A specific setting that improves how the emulator handles complex mathematical operations for graphics. While it can be more demanding, modern optimizations allow even low-end devices to enable it for better visual accuracy without losing stable FPS.

One of the most common hurdles for new Citra users is "shader stutter." When a game requests a new visual effect or enters a new area, the emulator must compile the necessary shader instructions for your specific GPU. This process takes a fraction of a second, but it creates a noticeable hitch in gameplay. To solve this, Citra utilizes a shader cache. As you play, the emulator stores compiled shaders on your disk. The next time you encounter that specific effect, Citra loads it instantly from the cache, resulting in fluid movement. Many enthusiasts share pre-compiled shader caches for popular titles like Pokemon or The Legend of Zelda, though these must often be generated on your own hardware to ensure compatibility with your specific drivers. While it can be more demanding, modern optimizations
