What is OptiFine

OptiFine is the most popular optimization mod for Minecraft. It rewrites the game's rendering, adds dozens of graphics settings and boosts FPS even on weak PCs. It's a must-have for anyone who wants a smooth picture and gorgeous shaders.

On top of performance, OptiFine unlocks HD textures (high-resolution resource packs), built-in shader pack support, a zoom camera, dynamic lighting from torches in your hand, and fine-tuned render distance. One mod does the job of several.
