Lithium

Optifine is a popular mod in the Minecraft community for enhancing graphics and performance, but recent instability and delays in the release of Optifine 1.21 have led players to seek alternatives. 1. Sodium is an optimization mod for Minecraft built on the Fabric mod loader that boosts frames per second (FPS) and resolves graphical glitches. It works well with other mods, particularly Lithium. 2. Iris Shaders is an alternative for players who want shader support and requires Sodium to function. It supports various Optifine shader packs and enhances both performance and visuals when paired with Sodium. 3. Lithium is a Fabric mod that improves game physics, mob AI, block ticking, and world generation, resulting in increased game speed and frame rate. It is compatible with Sodium and Phosphor. 4. Fabulously Optimized is a modpack that includes Sodium, Lithium, and other optimization mods, aiming to enhance game speed while replicating features of Optifine, such as shaders and zoom functionality. 5. Simply Optimized is a modpack containing 18 mods, including Sodium and Lithium, focused on performance improvements without additional visual enhancements. It is regularly updated for compatibility with new game versions.
