Shader compilation was a time-consuming process, and when gamers launched a game on Yuzu, the emulator had to compile shaders on the fly. This led to frame rate drops, stuttering, and an overall poor gaming experience.
Tips for controller and boost of FPS/quality (shader cache) : r/yuzu shader cache yuzu
To grasp the shader cache, one must first understand shaders. In modern 3D graphics, shaders are small programs that tell your GPU how to draw specific effects: the reflection on a sword, the ripples in water, or the shadow of a tree. When Yuzu emulates a Switch game, it reads the game’s original shaders (written for NVIDIA’s NVN API) and must translate them into a language your PC’s GPU understands (OpenGL or Vulkan). This translation is computationally expensive. Shader compilation was a time-consuming process, and when
