Benchmark Sodium VS Mercurizer

About this Mod

mercurizer

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 β€” 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 β€” 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 β€” 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 β€” upload fraction cuts quickly when frames spike, recovers slowly when stable, preventing the oscillation that causes micro-stutters
  • VSync-aware β€” automatically applies a more conservative upload budget when VSync is enabled to avoid blocking the render thread
  • Safety mode for old hardware β€” Intel Gen 8 and older, and certain AMD driver configurations, automatically get conservative single-threaded settings that prevent driver crashes
  • Real low-end benchmarks β€” tested on actual budget hardware. 37 FPS to 114 FPS on integrated graphics β€” 3.08x Sodium's performance!

Frequently Asked Questions

Does Mercurizer need to be installed on the Minecraft server?

No. Modrinth marks Mercurizer as unsupported on the server side. Install it only in your local Minecraft mods folder. Your server can remain unchanged unless the mod page lists an additional dependency.

Which version and loader does Mercurizer require?

Use a file for fabric and your exact Minecraft version. Supported versions include 26.2, 26.1.2, 26.1.1. Files for different loaders are not interchangeable.

Mercurizer is not working – what should I check?

First check the Minecraft version, loader version and required dependencies. Put the .jar file in your local .minecraft/mods folder and remove older duplicates. Because this mod is client-side, adding server RAM will not fix it.
