Chronos Shaders (1.20.1, 1.19.4) is a very special shader, when you move the entire world will look very blurry and noisy. However, when you stand still the pixels will gradually become clear and you will see something wonderful ahead.
In terms of mathematics, Chronos has the most accurate Ray Tracing among all Minecraft shaders. However, logically speaking, Chronos may not be usable unless you have a supercomputer.
Chronos is designed with advanced technology and is only used for taking screenshots. This is because if you move the camera, even at the smallest angle, the entire scene will be rendered again. Depending on your computer, this rendering process can take a long time.
