FastSpawner: Optimize Mob Spawner Rendering for Better Performance

FastSpawner intelligently optimizes spawner rendering to boost your FPS without sacrificing functionality. Perfect for technical Minecrafters and performance-focused players!

🔧 Key Features

Shift-to-View Entities
- Spawner display entities (rotating mobs) only render when you hold Shift.
- Reduces GPU load in spawner-heavy areas like farms or adventure maps.
Adjustable Particle Rendering
- Control spawner particles (fire/smoke) via a 0-100% slider (default: 50%).
- Particles dynamically render at your chosen rate using smart randomization.
Seamless Embeddium Integration
- Configure everything in-game via Video Settings → Performance (Embeddium/Iris menu).
- No manual config editing needed!
