Mercury

I find Mercury to be a great choice for players who want Minecraft to run smoother but still feel like the original game. Mercury keeps the game stable, uses resources efficiently, and stays true to the vanilla look.

Under the hood, Mercury uses mods that help the game run faster. Those mods are Sodium, Lithium, FerriteCore, ImmediatelyFast, Entity Culling, MoreCulling, Dynamic FPS, and FastQuit. Mercury also lets you add Iris, which supports shaders so you can make the visuals prettier without losing the performance boost.

Mercury also adds tweaks for everyday gameplay. You get Mod Menu, Mouse Tweaks, Zoomify, Reese's Sodium Options, Sodium Extra, and Cubes Without Borders. E4mc lets you easily share a world with friends.

Mercury works on Fabric loader versions of Minecraft. You can just install and start the pack like usual. All the needed components Fabric API, Cloth Config, and Fabric Language Kotlin are bundled with Mercury.

The pack has No License, meaning you are free to edit it or even publish your own modpack based on it.

Have fun!
