By default, Ryujinx stores shader caches locally on your drive. You can usually find them here:
C:\Users\[YourUsername]\AppData\Roaming\Ryujinx\games\[GameTitleID]\cache\shader
Note: The AppData folder is hidden by default in Windows.
In modern 3D graphics, a shader is a small program that runs on your GPU. It tells the graphics card exactly how to draw every pixel, vertex, or geometry—handling lighting, shadows, reflections, textures, and effects. ryujinx shader caches
The Nintendo Switch uses a specific GPU (NVIDIA Tegra X1) and a proprietary shader language. Ryujinx (a Switch emulator for Windows, Linux, and macOS) must translate those Switch shaders into instructions your PC's GPU can understand (like GLSL, SPIR-V for Vulkan, or MSL for Metal). This translation process happens on the fly or is saved for reuse.
Cause: Driver mismatch or corrupt cache. Fix: Delete the cache and let Ryujinx rebuild it fresh. Update your GPU drivers to match the cache’s driver version if possible. By default, Ryujinx stores shader caches locally on

This translation process is computationally expensive. When a game renders a new effect or area for the first time, the emulator must compile the shader, causing a momentary freeze or "stutter." The shader cache stores these compiled binaries on the storage drive. Upon subsequent loads, the emulator reads the pre-compiled shaders from the disk rather than re-compiling them, effectively eliminating stuttering for areas previously visited. Unlike some emulators (e
Unlike some emulators (e.g., Cemu for Wii U), Ryujinx does not use a universal, user-friendly "transferable shader cache" format by default. Instead, it uses a per-game, per-GPU-driver database.
