🚀 Prism Performance | Adaptive Optimization for Minecraft 1.21

w

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

w

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
