Mods
ImmediatlyFast : is a performance optimization mod designed to significantly reduce stuttering and improve overall framerates (FPS) in Minecraft.
It achieves this by replacing the game's default renderer with a highly optimized version, leading to faster loading times and much smoother gameplay, especially in large modpacks RaphiMC♥
IrisSHADERS ( for shaders supports ) : is a powerful and open-source mod that acts as a modern replacement for the traditional rendering engine in Minecraft. Its main purpose is to allow players to easily use shader packs with much better performance and compatibility than older shader mods coderbot♥ IMS♥
Lithium : is a general-purpose optimization mod that focuses on improving various aspects of game physics, chunk loading, mob AI, and other server-side (or single-player) mechanics without compromising vanilla parity.
Unlike visual optimization mods (like Sodium or Iris), Lithium improves the logic and processing speed of the game itself.
Key Benefits:
Reduced Lag: Significantly reduces server-side lag (tick time) and improves the responsiveness of the game.
Compatibility: Works seamlessly with most Fabric mods because it only optimizes existing mechanics caffeinemc♥
Sodium ( and Sodium extra ) : a revolutionary, free, and open-source rendering engine replacement for Minecraft. Its primary goal is to drastically increase framerates (FPS) and reduce micro-stutters, particularly on low-end and mid-range hardware caffeinemc♥
