- [All Versions] Leaf Culling: Ports OptiFine's smart foliage rendering options
- [All Versions] Entity Stacking Optimization: Merges nearby dropped items and experience orbs when entity density is high, similar to Spigot's optimization
- [All Versions] Chest Rendering Optimization: Replaces dynamic chest models with static block geometry (removes opening animations for better performance)
- [All Versions] Distant Entity Tick Reduction: Stops ticking entities and fluids that are far from the player
- [All Versions] Dynamic FPS: Automatically reduces framerate when the game window is unfocused (1 FPS) or minimized (pauses rendering)

- [All Versions] GL Error Suppression: Eliminates spurious GL error log spam
- [All Versions] GPU Plus: Fixes video memory leaks and introduces new OpenGL 4+ features
