Aroko's Optimization Pack
Java modpack listed for Minecraft 1.21. Downloads from the MC Java Mods app on Android.
I don't know my version or loader
Open the Minecraft launcher and look at the profile you play on — it names both, like fabric-loader-1.21.4. The version also shows in the bottom-right corner of the game's main menu.
No loader in the profile name? Then it's plain Minecraft, and these mods won't run — you need Fabric or NeoForge installed first.
This modpack focuses on FPS improvements, improves ping numbers, and still allows for quicker movement on the title screen.
This modpack also allows you to freely add shaders, texture packs, etc.
One note before downloading this modpack. It may be difficult to handle for some people because it contains too many mods.
So, enjoy a pleasant Minecraft experience!
