A "shader" is a small program that tells your GPU (Graphics Processing Unit) how to render specific effects—lighting, shadows, reflections, or textures. When you play a game, the GPU must compile thousands of these shaders on the fly. This compilation takes CPU power and time. To avoid re-compiling the same shader every time you play, the system stores compiled shaders in a .
