As of version 1.2.0 Redmium also supports shaders, im too lazy to edit the whole description.

About Redmium

Redmium is an ultra lightweight modpack specifically crafted for low-end devices such as laptops, office computers and even phones using java launchers to massively increase FPS and lower RAM usage, it has excellent compatibility with other mods and old devices. It uses only the essential mods and focuses on pure performance.

It is recommended to use Java 25 with Redmium for optimal performace.

Performace

This version of Redmium is made just for increasing FPS, so it doesn't support shaders or has any additional mods.

Features

Redmium only adds Sodium Extra and Reese's Sodium Options, any other mod is for optimisation. Shader support is here since 1.2.0

Why use Redmium

Redmium has the lowest RAM usage and highest performance than any other optimisation modpack.

Redmium will always be compatible with almost all mods and also the oldest devices.

Redmium will work with only about 0.9GB of RAM, which is something no other modpack has done in the latest version of Minecraft.

Redmium will have frequent updates, and update to latest versions of Minecraft fast with beta versions of the modpack.

It has the highest performance compared to any modpack available on the internet, and no one will ever do it better than Redmium! (maybe)

I use it because it's the most widely used and easy to understand.
