Mercurizer
Better performance for low-end PCs, potato PCs, and on mobile. Possibly also on some mid- or high-end PCs
Quick answer
Which Mercurizer release should I use?
Mercurizer 0.9.1+mc26.2-1.2 targets 26.2 with Fabric. It must be installed on the client. Do not install it on the dedicated server. All 1 required mods have matching files.
Where it goes
Is Mercurizer required on the client, server, or both?
It must be installed on the client. Do not install it on the dedicated server.
This file is marked client-only.
What else does Mercurizer 0.9.1+mc26.2-1.2 need?
0.9.1+mc26.2-1.2. Change the file and its required mods may change too.
Install Sodium first. We found matching files for this game-version and loader setup.
We only count dependency files that match this setup. A file for another loader does not fill the gap.

About this project
What does Mercurizer add?
A Sodium addon built for hardware that can't handle Sodium.
Most "performance" mods assume you have a dedicated GPU and at least 8GB of RAM. Mercurizer doesn't. It's a Sodium addon designed specifically for integrated graphics, 4GB of RAM, and the kind of PC that struggles with Windows 10.

Sodium is great — but it still has a performance floor that leaves a lot of players behind, especially in developing countries where "gaming PC" means integrated graphics and 4GB of RAM, not a GTX 1080 Ti.
Mercurizer goes further. The goal is simple:
Give players with low-end hardware the ability to play Minecraft at a smooth framerate.
What makes it different from plain Sodium?
- Auto-tuning benchmark — on the first 3 launches, Mercurizer benchmarks your GPU upload bandwidth, round-trip driver latency, and CPU throughput, then automatically tunes chunk upload budgets and texture animation thresholds to match your exact hardware. Results are averaged across all 3 runs for accuracy, and re-run automatically if you change GPU or drivers
- Adaptive refinement — after 30 seconds of stable gameplay, Mercurizer refines its tuning based on real in-game frame times, improving accuracy beyond what the startup benchmark alone can achieve
- Anti-stutter recovery — upload fraction cuts quickly when frames spike, recovers slowly when stable, preventing the oscillation that causes micro-stutters
- VSync-aware — automatically applies a more conservative upload budget when VSync is enabled to avoid blocking the render thread
- Safety mode for old hardware — Intel Gen 8 and older, and certain AMD driver configurations, automatically get conservative single-threaded settings that prevent driver crashes
- Real low-end benchmarks — tested on actual budget hardware. 37 FPS to 114 FPS on integrated graphics — 3.08x Sodium's performance!

Specs: MacBook Air 2017, i5-5350U, 8GB RAM, Intel HD Graphics 6000, Debian 13 (KDE Plasma)
