This modpack add better visuals and Q.O.L.I features. But also better visuals. If you want a better vanilla minecraft experience that doesn't add to much than this is the modpack for you! Also if you want to play on a vanilla server the only thing I would disable is the minimap mod the world map mod and freecam. Other than that this 100% works on servers! You do not need a good computer to run this I dont even have that good of a pc. Anyway enjoy the modpack!
