Description

This is a slick modpack with tons of features to improve quality of life and performance, all whist keeping blocks and items vanilla! It inclues some of my favourite resource packs and shaders, and tons of QoL mods, some of which you may not have heard of.

I've spent lots of time optimising it, to the point that it boosts frames more than seems possible. There's so much optimisation I don't even know how it got to this point. Even a potato could run shaders with this. I mean it's more optimised than Fabulously Optimised!

It should be legal for most servers too - some specific mods (such as Freelook) are banned on certain servers, so make sure to check server regulations beforehand - but for private SMPs this is great: no unfair advantages, just a polished experience.
