This is frustrating and usually indicates that your shader cache is being invalidated. This can happen for several reasons:
Yuzu has implemented environment variables to prevent other software from interfering with the driver's shader cache. By setting __GL_SHADER_DISK_CACHE_PATH , Yuzu forces the cache directory to be inside its own user directory, protecting it from malware. Setting __GL_SHADER_DISK_CACHE_SKIP_CLEANUP prevents the driver from automatically cleaning up older cache entries, creating an unbounded cache size. This implementation is currently available mainly on Windows.
Unexplained, permanent drops in performance in areas that used to run smoothly. How to Fix Corrupted Shaders
happens when the emulator translates Switch code into PC graphics language (Vulkan or OpenGL). The Cache is a saved file storing these compiled shaders. yuzu shader cache
: The first time a game requests a specific visual effect (like an explosion or a new menu text), Yuzu pauses for a fraction of a second to compile the shader. This causes a sudden drop in frames per second (FPS), known as compilation stutter.
Yuzu utilizes two primary types of caches to improve the user experience: Transferable Pipeline Cache : These are hardware-agnostic files (typically opengl.bin vulkan.bin
There are two ways to find your shader cache files. This is frustrating and usually indicates that your
: While users often share complete cache files online to help others avoid the initial "build-up" stutter, these are frequently invalidated when yuzu updates its shader version. It is generally more stable to build your own cache by simply playing the game. Pro Tip for NVIDIA Users
Managing your cache files is straightforward once you know where Yuzu stores them. Locating Your Cache Folder
This is a "hack" that allows the game to continue running while shaders are being compiled in the background. How to Fix Corrupted Shaders happens when the
How To Install Shader Cache, Game Updates And DLC's (Yuzu Guide)
To combat shader stutter without requiring a massive, pre-built cache, Yuzu introduced a groundbreaking feature: .
