In modern video games, shaders are small programs that tell your GPU (Graphics Processing Unit) how to render (draw) specific effects. This includes lighting, shadows, reflections, water ripples, and even the color of a character’s shirt. Every time you look at a different angle in a game, the GPU runs thousands of shaders instantly.
