One of the best mods to improve FPS in vanilla Minecraft is Fastcraft. Fastcraft speeds up the game by caching resources and making changes to the way the game runs. It provides significant FPS boost, especially on older computers. Some additional benefits of Fastcraft include:
- TPS/simulation improvements through faster code and better algorithms
- Lag spike elimination from world generation, light calculations, and chunk loads[^4^]
- Download the Fastcraft mod from a trusted source.
- Locate your Minecraft installation directory.
- Open the "mods" folder within the Minecraft installation directory.
- Place the downloaded Fastcraft mod file into the "mods" folder.
- Launch Minecraft and enjoy the improved FPS.
- Disabling particles separately for better performance
- Dynamic light option, allowing light sources to emit light even when not placed down
- Texture zoom and the ability to disable fog for a more enjoyable experience
- Download the Optifine mod from the official Optifine website or a trusted source.
- Locate your Minecraft installation directory.
- Run the downloaded Optifine installer, selecting the "Install" option.
- Launch the Minecraft launcher and select the Optifine profile.
- Adjust the Optifine settings according to your preferences.
- Allocating more RAM to Minecraft: By allocating more RAM to Minecraft, you can improve its performance. You can do this by opening the Minecraft launcher, clicking on "Installations," selecting your version, and increasing the allocated RAM under the "More Options" section[^1^].
- Using performance-enhancing mods: Mods like Sodium, Lithium, and Phosphor are specifically designed for performance optimization in Minecraft. Sodium replaces the game's rendering engine, improving frame rates and reducing stuttering. Lithium optimizes game physics, mob AI, and block ticking. Phosphor improves lighting performance and reduces lighting errors[^1^].
- Adjusting in-game settings: Lowering the render distance, turning off fancy graphics, reducing particles, and disabling VSync can also help improve FPS in Minecraft[^1^].
