This should be set to x1.42 by default, but you could jack it up as high as x2, or even x4, though you should expect a drop in frames for doing this unless you’re using a high-end PC. vsh files, open them with a text editing program like Notepad, and find the line for render resolution. Unlike many shader packs, you can actually make adjustments to the inner workings of Chocapic13’s Shaders, which will increase quality at the cost of performance and vice versa. The light and shadow effects aren’t limited to just a couple of biomes either – everywhere you go in Minecraft, right up to 1.18.x, you can see this mod at work. One of the best effects is actually the fog, which couples very well with dark and rainy nights to create a moody atmosphere which would be perfect for a horror map if you just played with some settings to keep the world constantly dark and stormy. There are few shader packs with lighting effects as good as those you will see in Chocapic13’s Shaders, and that includes the other packs which were created using this one as a foundation.

Thanks to updates as recent as February of 2021, Chocapic13’s Shaders work great with Minecraft 1.19.x, and old versions.

It is highly popular among shader pack developers because it is easy to work with, and many of the simplest things have already been taken care of, which leaves those developers time to work on the large changes and modifications they want to make.

Chocapic13’s Shaders mod is the baseline for many other shader mods out there, as you can learn just from checking a number of shader pack pages in places like Minecraft Forum.
