Features
- Rendering Optimization: This mod reduces the load on your computer by limiting the number of entities rendered within a specified range and dynamically adjusting the rendering position of entities based on the player's location. This means smoother gameplay in areas with more entities.
- Global Graphics Settings Adjustment: Select from Ultra High, High, Normal, Low, or Very Low to instantly adjust your graphics quality, view distance, and more, without the need for manual tweaking of individual settings.
- Quick Toggle for Mob Rendering: Configure which mobs to render via the GUI, eliminating the need to manually edit configuration files and restart the game.
- A Series of Minor Features: Download this mod to discover more features!
Actual Effects
In a large Skyblock pack, players rapidly right-click on dirt to obtain a large number of gravel. The optimization is noticeable, with frame rates stabilizing from an unrestricted 14 FPS to a smooth 52 FPS.
