Sodium Relief

🚀 Smooth your Minecraft inventory experience

Minecraft inventories can feel slightly stuttery — especially when hovering items, opening chests, or using modded GUIs.
Sodium Relief is a lightweight, client-side optimization mod that reduces small tooltip and hover-related stutter without changing gameplay.

⚙️ What it does

Smooths tooltip rendering on inventory-like screens

Reduces redundant tooltip recalculations

Stabilizes hover behavior when moving the cursor across items

Caches text-width measurements for repeated strings (like item stack counts)

Improves responsiveness in chests, menus, and modded interfaces

📊 Measured impact

The effect is less redundant work, not more frames — so it’s measured as tooltip builds avoided, not FPS. The numbers come from an automated in-game test that opens a real inventory screen, hovers items, and counts the actual tooltip builds it reused instead of rebuilding every frame:

| Scenario | Tooltip draws | Real builds with Sodium Relief | Avoided |
| — | — | — | — |
| Resting on one item | 2,429 | 2 | 99.9% |
| Scanning 36 items (3 passes) | 3,714 | 38 | ~99% |

Each tooltip build was measured at ~0.1–0.3 ms, so the reuse avoids roughly half a second of CPU work over the ~20-second test — work that would otherwise land as tiny per-frame hitches while you hover. Near-identical across the whole 1.21 – 26.2 range, and reproducible — every measurement is exported as a raw snapshot, and you can capture one yourself any time from the Export Benchmark button in the settings.

🧠 How it works

Sodium Relief optimizes the tooltip pipeline by:

• caching tooltip layout results (LRU + TTL)
• reusing previously computed tooltip data on unchanged hovers
• avoiding unnecessary recomputation during fast cursor movement
• caching repeated text-width measurements instead of recomputing them every frame
• applying lightweight hover-smoothing logic

All optimizations are client-side, safe, and designed to work alongside Sodium. When in doubt about an item or screen, it falls back to vanilla behavior.

🎯 When it helps

You’ll notice the biggest improvement when:

• opening large inventories (chests, storage systems)
• quickly hovering over many items
• using mods with heavy or complex tooltips
• experiencing subtle UI micro-stutter

❗ What this mod does NOT do

• ❌ Does NOT increase FPS in the world
• ❌ Does NOT optimize chunks, rendering, or GPU load
• ❌ Does NOT act as a general performance booster

This is a focused GUI-smoothness mod, not a full optimization suite.

🧩 Compatibility

• ✔ Fabric — Minecraft 1.21 – 1.21.11 (Java 21) and 26.1.x / 26.2 (Java 25)
• ✔ Client-side only
• ✔ Requires Fabric API · works best alongside Sodium · Mod Menu optional
• ✔ Server-safe (no gameplay changes)
• 🌍 Available in English, Russian and Ukrainian

💡 Why use Sodium Relief?

Most performance mods focus on rendering or world logic.
Sodium Relief focuses on UI smoothness — solving a small but noticeable source of micro-stutter that’s usually ignored.

📦 Installation

1. Install Fabric Loader + Fabric API
