If you want a modpack that speeds up the game performance for both client and server this modpack is for you
It basically upgrades the game math and makes it more efficient.
If you think the game looks a bit pixelated and you don't like it you can disable Super Resolution (you shouldn't feel a very big fps drop).
If you see any type of laggy GUI disable Exordium if you want (the mod limits the GUI and screens at a lower framerate to speed up the worldrendering)
If you have any problems with the create mod farms disable immersive optimization
