Modern Switch games use complex graphics. When your PC sees a new effect (like an explosion or a menu) for the first time, it has to build it from scratch. Precompiling bypasses that guesswork.
Ryujinx is an open-source Nintendo Switch emulator. A critical component of its performance pipeline is the translation of the Switch's GPU shader language (NVN/NVIDIA) into a format executable by the host PC's graphics API (Vulkan, OpenGL, or Metal). "Pre-compiling shaders" refers to the process of translating these shaders before gameplay begins, rather than "Just-In-Time" (JIT) during active rendering. This process eliminates "stuttering" (micro-freezes) caused by on-the-fly compilation. ryujinx precompile shaders
