VRAM Drop & EntityBlock Culling

## VRAM Drop

VRAM Drop is an optimization system designed to reduce unnecessary GPU memory usage by intelligently managing unused rendering resources.

### Features:
- 🧹 Intelligent cleanup of unused graphical resources.
- 🖼️ Reduces memory usage from unnecessary textures and rendering data.
- 📉 Helps prevent VRAM overflow in large worlds and modpacks.
- 🔄 Optimizes temporary rendering caches.
- ⚡ Improves stability on GPUs with limited VRAM.

### Benefits:
- Lower VRAM consumption.
- Reduced stuttering caused by memory pressure.
- Better performance in large environments.
- Improved GPU resource management.

### ROV Integration:
VRAM Drop works together with:
- **Render Only FOV** → avoids rendering objects outside the player's view.
- **BlockEntity Culling** → prevents invisible Block Entities from being rendered.
- **Particle Culling** → reduces unnecessary particle rendering.

> **Goal:** Keep only necessary resources loaded in memory, reducing VRAM waste while maintaining visual quality.
