Feather FPS Boost Mod is a lightweight, general-purpose performance optimization addon for Minecraft Bedrock Edition, designed to improve frame rate stability and overall smoothness while keeping the vanilla look intact.
✅ Works on existing worlds | ✅ No experimental features required | ✅ Achievement friendly | ✅ Bedrock 1.21.0+
Feather focuses on client-side rendering overhead and spawn density, the largest sources of lag on Bedrock devices.
| What | Impact |
|---|---|
| 186 particle types handled | 177 removed outright, 9 potion, spell and gas effects kept but trimmed |
| 42 of 80 block animations frozen | Water, lava, magma, bubble columns, kelp, campfires and portals stop cycling frames |
| Fire animation halved (32 → 16 frames) | Half the texture cycling cost on fire and soul fire, while staying readable |
| Three fog modes | Overworld, Nether, End and sulfur caves each cull distant geometry earlier |
| No volumetric fog cost | None of the pack's fog definitions use Vibrant Visuals volumetrics |
| Blocky Vibrant Visuals shadows | Removes per-edge shadow filtering when VV is on |
| Spawn density reduced across 35 mobs | Herd sizes, spawn weights and density limits trimmed |
| Entity sound volumes trimmed | 85 mobs, 44 individual events and 40 sound definitions pulled down |
| Colormaps desaturated at 64×64 | Less VRAM, more natural tone, no neon green foliage |
| Sky and weather textures downscaled | End sky, end flash and rain splash reduced to 1×1 |
Pick one from the subpack list when you activate the pack, and switch at any time:
Built primarily for low-end and mid-range devices — phones, tablets, and older PCs that struggle with vanilla Bedrock's visual load. Stuttering during mob spawns, lag in built-up areas, and thermal throttling during long sessions are the exact problems this pack targets.
Not touched: crafting, physics, progression, world generation, loot, mob AI, pathfinding, attacking, or any core game logic. Colormaps are desaturated for a more natural tone but do not affect block data or biome logic. Achievements stay enabled.
Changed, and worth knowing: the behaviour pack trims herd sizes, spawn weights and density limits on 35 mobs. Passive animals spawn in smaller groups than vanilla — a cow herd is 2 instead of 4. This is where a large share of the FPS gain comes from, but it does mean mob density is visibly lower. If you want untouched spawning, run the resource pack on its own; it works standalone.
