Boosting FPS in Mangrove Swamps and Dense Forests

Biomes packed with overlapping foliage—especially mangrove swamps, jungles, and thick oak or birch forests—force your computer to process thousands of hidden leaf blocks at once. On low-end hardware, skipping those inner leaf layers can deliver up to a 30 percent performance increase in dense areas.

Reducing Inner Leaf Calculations

1. Return to the game main screen and open Mod Menu.

2. Find Cull Less Leaves in the list and open its configuration settings.

3. Adjust the number of rendered leaf layers downward so the game stops calculating deep, hidden foliage while still keeping an outer shell of leaves.

4. Save your settings and load back into your world.

Testing Performance in Heavy Biomes

Travel to a mangrove swamp or a dense forest landscape where your frame rate usually dips. Press F3 to open the debug screen and watch the FPS counter in the top-left corner while looking directly through multiple rows of trees. If your frame rate still struggles while moving through heavy foliage, return to the configuration menu on the main screen and lower the custom leaf layer amount further until movement feels smooth.
