With this modpack you can very very boost your Minecraft if you play on an old pc. Me playing Minecraft on an 20 years pc and with no mods i have stabile 60 fps but i play whit my friend with many many mods and i had just 11 fps but whit this modpack i have 30 fps so this is a good performance booster. I recommend this modpack for everyone that has an old pc and would like play with mods/modpacks. There are FPS booster and chunk loading booster.
