In the video settings, one way to improve FPS is to lower the Biome Blend slider. The game has a lot of biomes that are adjacent to each other.
Simulation distance determines how many parts are active in terms of crowd movement, water or lava flows, and general random tick activity.
This is the easiest way to increase the FPS in the game. Newcomers unfamiliar with complex video settings may reduce the normal 'Graphics' settings to 'Fast'.
When gamers are in the world, they'll be able to see biomes pop up to the horizon. As they progress, the map continues to load.
If players make changes to all of these video settings and are still unsatisfied, they can look to specialized third-party graphical modifications like Sodium, Optifine, BetterFPS, etc.
