About this project

What does Mercurizer add?

Sparked Hostmercurizer

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.


why

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!

Benchmark

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

Settings: 16 chunks render distance, Vsync off, rest is vanilla, in a normal world (no superflat/amplified/etc)
