Some games have a type of stutter that happens no matter how powerful your computer is, or which settings you choose. This is caused by a process known as “shader compilation,” and it’s a growing issue in PC gaming.Shaders are computer programs that help determine various aspects of rendered graphics.
Pixel shaders, for example, calculate the attributes of a pixel. This includes the color, brightness, reflectivity, or transparency of that pixel.
If you want something in your game to look wet, you use a special shader to achieve that look rather than do it painstakingly by hand.Shaders are what make modern GPUs so flexible since these GPUs are designed to run anything that can be expressed in shader programming language.
They replace the old “fixed-function pipeline” GPU technology where the types of graphical math a GPU could do were hard-wired into its silicon.“Compilation” is a computer term that refers to taking the code as written by a human programmer and translating it to machine code that the specific processor that’s meant to run the software in question can understand.Read more on howtogeek.com
