Optimized Fabric assembly for FloweryMC (1.21.4)
Build FloweryMC uses a modified Fabric build for Minecraft 1.21.4, which combines maximum performance with pure vanilla gameplay.
🔧 Technical features of the assembly
1. Base: Fabric Loader + Optimization Mods
- Fabric API is the basic library for mods.
- Lithium – optimization of game systems (physics, mobs, world loading).
- Starlight – a rewritten lighting system (faster than vanilla).
- Krypton – network stack optimization (less lag in multiplayer).
- FerriteCore – reducing RAM consumption.
2. Additional mods for stability
- Smooth Boot – Improves game and server loading.
- LazyDFU – speeds up startup by delaying initialization of some systems.
- Memory Leak Fix – Prevents memory leaks.
3. Plasmovoice – voice chat
- Plasmo Voice 2 – modern voice chat with:
- 3D sound (you can hear where the player is speaking from).
- Low latency (optimized codec).
- Flexible settings (communication radius, groups).
⚙️ Why Fabric and not Paper/Spigot?
- Better compatibility with mods (if client mods are added in the future).
- Pure vanilla gameplay – No mechanic changes like in Paper.
- Flexibility – you can add any QoL mods without switching to Forge.
