Before you go on installing it and calling it a day. Make sure you chose the version you want to play with first. I have the modpack for both newer and older versions for the users hardware and such! (Things like older OpenGL so you can only run 1.16.5 or just low pc specs in general.) FYI, I have it in beta because I haven't experienced these as much as I can so there might be bugs or might not be.
Most Recent version that it supports as of updates: 1.21.5
Oldest version it supports as of updates: 1.16.5
This was made to help the user experience Minecraft a little easier by outright removing lag as much as it can. It also adds extra customizable mods that can help you have a more visually interesting experience as well while still being purely vanilla! If you want a more Vanilla+ experience, checkout my Modpack called "Korevix"!
If you find any issues with the modpack on a specific version, please message me and I will gladly fix it as I can't really manage so many different things and there bugs.
