!!install!! — Ryujinx Totk Shader Cache

Sharing shader caches can cause emulators to crash if the cache was built on a different Ryujinx version, a different graphics API, or a different GPU vendor (e.g., transferring an AMD-built cache to an Nvidia system).

The best way to bypass the initial stuttering is to download a pre-built shader cache file from another player who has already "compiled" the shaders by playing through the entire game. This allows you to benefit from their playthrough.

Check your storage drive. Shader caches read and write data constantly. If Ryujinx or your cache folder is located on an old mechanical Hard Drive (HDD), the drive cannot feed the data to your CPU fast enough. Always host your emulator and game files on a high-speed Solid State Drive (SSD or NVMe). Advanced Performance Tips for TotK ryujinx totk shader cache

Instead of risking instability with third-party caches, rely on Ryujinx’s Vulkan backend and profile-guided compilation. The emulator compiles shaders so quickly now that within 2 to 3 hours of organic gameplay (exploring the sky, surface, and a few shrines), you will have accumulated the vast majority of common shaders, and the stuttering will virtually disappear.

Sharing shader caches technically involves distributing copyrighted game code, violating piracy laws. Sharing shader caches can cause emulators to crash

Tears of the Kingdom is not an ordinary game. Its open world is enormous, its physics engine is incredibly complex, and its shader count is substantial—likely encompassing tens of thousands of individual shaders. Without a shader cache, every new location, weather effect, enemy encounter, and ability activation would trigger a compilation event, leading to constant, disruptive micro-stutters that ruin immersion and make combat and exploration frustrating.

As a result, Ryujinx must translate or recompile every single one of these shader programs so your PC's GPU can understand them. The "simplest" approach is to recompile them in real-time as you play. However, this translation process takes time. This time lag is what causes the dreaded "shader compilation stutter"—a sudden, jarring freeze or frame drop that occurs the first time you encounter a new effect or area in the game.

Ryujinx have a “pre‑compile all shaders” button – you must encounter content in‑game.

Set this to Vulkan for the best performance on most modern hardware.
