🚀 Prism Performance | Adaptive Optimization for Minecraft 1.21

Prism Performance is a client-side optimization mod for Minecraft 1.21 focused on improving frame rate stability and reducing stutter through adaptive performance techniques.
🧠 Adaptive Performance System
Prism dynamically adjusts multiple in-game systems in response to real-time performance conditions instead of relying on static settings.
-
Dynamic Render Distance Scaling
Automatically adjusts render distance based on current FPS thresholds. -
Entity Culling
Prevents rendering of entities outside the player's view using visibility checks. -
Animation Throttling
Reduces update frequency of non-essential animations during low FPS situations. -
Frame Stabilization
Helps maintain consistent frame pacing during sudden load spikes.
📊 Performance Monitoring HUD

An optional in-game overlay provides real-time performance feedback:
- FPS indicator with color states (stable, variable, critical)
- Frame time monitoring (ms)
- Memory usage tracking (MB)
- Customizable layout, colors, and scaling (F7 menu)
📈 Performance Benchmarks
Testing Environment:
- Minecraft Version: 1.21
- GPU: GTX 1650
- CPU: Ryzen 5 3600
- RAM: 16GB
Scenario: Survival world, 12 chunk render distance
| Setup | Avg FPS | 1% Low FPS |
|---|---|---|
| Vanilla | 72 FPS | 38 FPS |
| Prism Enabled | 110–120 FPS | 70–80 FPS |
Result: Noticeable FPS improvement and reduced frame drops in this test scenario.
🔁 Reproducibility
Performance results may vary depending on:
- Hardware configuration
- Installed mods
- World complexity and entity count
All tests were conducted in a controlled single-player environment.
