The Lightning Optimizations modpack aims to provide a comprehensive and efficient set of mods and configurations for improved performance and quality of life in the game. This modpack is designed to increase FPS, reduce lag and accelerate loading times, with numerous tweaks to maximize performance.
Although the modpack may appear to include a mix of performance optimizations and quality of life improvements, it is mainly focused on performance. It serves as a convenient option for new players, as it presents a curated selection of mods for optimal performance, rather than having to search for them individually. As of now, this modpack is the best choice for players looking to enhance their in-game performance.
