Optimazed

Optimazed modpack is designed to provide the most efficient enviroment you ever saw, without other features that slows the game.

It provides (for example) Dynamic FPS to minimize the FPS while running background or FPS Reducer while you're AFK.

If you are on a large server, you should not experience much FPS drop, because multiple mods are made for keeping FPS count on the maximum on these servers.

If you experience long ping time for servers, this modpack fixes that, so you'll be able to know if a server is offline or not.

If you have lower hardware, you will experience FPS raise in singleplayer or in servers. Of course you can download this on good hardware too, then you may experience more performance than the default vanilla game.
