Optimium

Optimium was originally intended for personal use, but I wanted to release it publicly.
Therefore, you can see mods from modpacks that are familiar to your eyes. But the purpose of almost every mod in these modpacks is to increase FPS, so I don't see much wrong.
You may also have seen a exclusive mod for Nvidia-only users called "Nvidium". But no worries, because if your video card is not from Nvidia or doesn't support the desired feature, the mod will turn itself off. In general, if there are any problems, you can delete the mod responsible.
Finally, "Optimium+", the modpack where I've included QoL and additions will be released soon. That modpack will be more personalized, but I don't think it will be bad. Those who like it can give it a try.
I hope this contributed to everyone, have fun!
