Yuzu usually detects this automatically and asks to delete it. Let it do so. Corrupted caches often happen when you update your GPU drivers.
This is the raw hardware cache built specifically for your exact graphics card and driver version. If you update your GPU drivers, this cache is usually invalidated and must be rebuilt.
This is completely normal and indicates that Yuzu is building your shader cache. The emulator is compiling console shaders on the fly, which momentarily impacts performance. This is a one-time cost for each visual effect.
Because compiling shaders manually by playing through a 100-hour RPG can be tedious, many players look to download complete, pre-compiled shader caches from the community.
If a new shader is encountered, the game skips rendering that specific effect for a split second and continues running smoothly while the shader compiles in the background. You might notice a temporary invisible object or texture pop-in, but your frame rate will remain perfectly stable. How to Optimize Yuzu Shader Cache Settings
This comprehensive guide breaks down what shader caches are, why they cause performance issues, and how you can optimize them for a flawless emulation experience. What is a Shader Cache?
Download a shader cache from a trusted source. Community pages often host a vast library of caches for various games and Yuzu versions. When downloading, pay attention to the shader version. At the time of writing, the current shader version is (as of 2024/1/27). Using version 1659 or below of the emulator would give you shader version 10. You'll want the most recent cache built for the latest version of the emulator.
Follow these instructions carefully. The process differs based on whether you use or Vulkan (Vulkan is recommended for modern games).
To understand why a shader cache is vital, you must first understand what a is.
Shaders are small programs that tell your graphics card (GPU) how to render light, shadows, textures, and 3D geometry.
