While most performance-focused modpacks aim at just higher FPS, this modpack focuses on optimizing the user experience and stability, as well, and yet still manages to outperform many in benchmarks.
The modpack does not provide any QoL or OptiFine-parity mods, but some deliberately selected mods to boost your gaming experience! Besides these optimization mods, the modpack also provides some essentials, like No Chat Reports, and other modpack-centric mods.
You are expected to add any non-optimization mods you want, yourself. If you face any issues, you are free to ask for help on our Discord server.
