What is Mercury?

Mercury is a simple, lightweight, Minecraft Performance Modpack, whose goal is to provide players with a significant FPS boost, while sustaining the quality and charm of Minecraft. It is created strictly for performance; no Quality of Life, no OptiFine features, no game-breaking visual adjustments, just speed. You can use Mercury both by itself for a vanilla FPS boost, as well as a foundation, a base model you can add onto to create your own mod pack. This is why Mercury has support for both Fabric and Forge, so that you can have increased FPS with any mods you desire.

Why choose Mercury?

Mercury greatly enhances the performance of Minecraft whilst reducing RAM usage, to assist laptops and low-end PCs. I will not be comparing speeds between other mod packs as it's practically impossible to host a fair benchmark, especially with varying results across PCs. But, I do encourage you to test performance speed across other mod packs (Adrenaline, FO, SO, OF) to see which works best for your PC.

Disclaimer: When comparing Mercury to Vanilla, please note that standing still will cause your FPS to slowly rise. A better representation of each client is to run and watch how your frames are maintained.

Why add Forge Support?

As stated previously Mercury provides support for Forge, with the same FPS improvements as Fabric. We do this by using Fabric/Forge mods, as well as utilizing ports of Fabric mods, which has gotten more popular in recent years. So if you intend to use Mercury to make your own Modpack, Forge Support has your back, allowing you to use all the mods!

Support the Mod Developers

Please remember that all of this is only possible because of the hardworking mod developers. Thank them, not us. Every one of the mods we use contributes to the performance of the pack. If you enjoy Mercury, go support the developers of the mods we used! Download their mods! Give them good feedback!

Mercury Plus

Want a good replacement for OptiFine that has a better FPS boost? Check out Mercury Plus! It has all the features of Mercury with some extra mods that emulate every feature of OptiFine (except capes). And besides OptiFine's features, Mercury Plus contains no Quality of Life mods. If you want superior FPS than OptiFine but still need connected textures, zoom, dynamic lighting, shaders, and more, Mercury Plus is for you!
