: Cache file is huge (500+ MB). Note : TotK’s full transferable cache can exceed 1 GB. This is normal. Large caches mean more pre-compiled shaders = less stutter.

In emulation, a shader is a program that tells your GPU how to render objects, lighting, and effects. When you encounter a new visual (like a specific explosion or a new weather effect), the emulator must "compile" these instructions for your specific hardware on the fly. This process causes the infamous or "micro-lags". Once compiled, these instructions are saved to your shader cache so your PC can instantly recall them next time, making the game smoother the more you play. Recommended Performance Settings
