About this Modpack
Triple your FPS with Mostly Optimized!
Here's what it does:
Mostly Optimized attempts to make minecraft be less laggy, have higher FPS, reduce lag spikes, load chunks faster, create worlds faster, and replacate every feature from Optifine. Some of those features are shaders, zooming, dynamic lighting, removing fog, fullbright, custom entity models, custom capes, higher render distance, better grass, randomized textures, Configurable animations and details, connected textures, and more, so if a resource pack or a mod says it requires Optifine to work you can get it working in Mostly Optimized! I also included some mods I personaly use but I tryed not to change to many vanilla mechanics, and if you don't like a certain feature in this modpack feel free to add or disable any mod/resource/data/shader pack you want to have the experience you want! . Thank you to Fabulously Optimized and Vanilla Perfected for the inspiration!
