hydrazine

Hydrazine is a gentle optimization mod for Minecraft. It makes the game run faster without changing how anything looks or plays. The short version: it speeds up the behind-the-scenes stuff.

What Hydrazine actually does:

• Packs terrain vertex data so the GPU reads half the data per block
• Reuses the terrain draw list instead of rebuilding it every single frame
• Loads chunks faster when the game is idle and protects your framerate when things get busy (no more loading stutter)
• Cuts entities, block entities and particles by distance before they ever reach the renderer

The result is more FPS, smoother frame pacing, and faster world loading.

In testing on a low-end integrated GPU (Intel i3-1215U UHD), Hydrazine took Minecraft from 70 FPS with constant stutter to 180 FPS with no stutter at 32 chunks of render distance. That is why Hydrazine is best for iGPUs and other weaker hardware, where every wasted frame really counts.

Hydrazine changes nothing about how Minecraft looks or plays. Same game, just less wasted work.

It plays nice with other mods too. If it sees another renderer mod like Sodium, it politely steps back and lets that mod take over terrain rendering.
