Vanilla Minecraft slow? Download this. Features many optimization mods and is vanilla-like. Shaders not included. Some bugs are fixed, so if you frequently utilize bugs, be warned.

If you're looking for raw performance, don't look to the forge and neoforge versions, while they have optimization mods, they mainly just exist to allow further compatibility. If you just want the vanilla experience, and don't plan on using exclusive mods, use the fabric version.

I plan to have the forge version of this mod be more legacy, if you think old is gold, you'll want the forge version, it supports older versions of minecraft. If you prefer rolling release and like sticking to super new versions, I'd reccomend fabric version.
