Love the clear, player‑friendly writeup you already have; here’s a refreshed version that matches the v2 upgrade and keeps your tone.
PotatoMode v2 – Smart FPS Booster (Fabric 1.21.4)
PotatoMode v2 is a lightweight, client‑side Fabric mod that boosts performance on low‑end systems by dynamically adjusting Minecraft’s built‑in video settings using real‑time FPS monitoring.
This mod does not replace the renderer or inject custom graphics pipelines. It simply manages vanilla options intelligently to reduce load when needed.
How It Works (Technical Explanation)
PotatoMode v2 continuously samples client FPS and frame time.
When performance drops below a configurable target, the mod applies staged optimizations in steps (Light, Medium, Heavy) instead of a single hard switch. These stages can be tuned with presets:
Balanced, Aggressive, and Extreme.
When FPS recovers above a separate Recovery FPS value, PotatoMode can gradually restore your original settings using Smart Restore.
Affected vanilla settings may include:
Render distance
Simulation distance
Particle count
Entity distance scaling
Cloud rendering
Smooth lighting
Biome blend
Mipmap levels
The mod is client‑only and never changes:
Game logic
World generation
Server performance
Renderer internals
It only modifies existing Minecraft client video settings.
