I hadn't yet figured out how to get my core-shader-rewriting resource packs to work with Sodium. So I made this modpack to make the game run better than in Vanilla while not harming compatibility with my resource pack shenanigans. For that reason it likely won't release on versions pre-1.21.11 unless I update my resource pack to an earlier version
Feel free to use this pack any way you want, but it's higly recommended not to use it outside of scenarios when you have to use core-game-shader resource packs and don't have a strong enough PC to run Minecraft at stable FPS
