Opti-dium
It's like Optifine, but with a little bit (actually, it's more than a bit) of Sodium and more optimization mods.

Basically, it's a mix of Optifine and most of the modern optimization fabric mods, like Sodium and Lithium...
Also, most of the mods are client-side! (98% of them are client-side)
- Also, you can replicate the trailer's graphics!
- Aaaand, with the Nostalgic Tweaks (client-side) and the Golden Days Resource Pack (or the Programmer Art Ultimate), you can replicate the old and nostalgic graphic of Minecraft!
- Infinite Delay Music!
- The chat is more manageable!
- Voice Chat! (if you got some friends, you can talk with the Proximity Chat Voice, which is cool, I think...?)
Thanks to all the modders and resource pack-ers!
