Integrate Sodium (or Iris) into vanilla!

OptiFine is stubborn. They don't allow anyone to use the mod in modpacks, and they refuse all your offers to even discuss integrating the mod into vanilla. And with 1.18 not being at it's best (performance-wise), we could really use an FPS boost without making the game look horrible or constantly upgrading the Java version.

So integrate Sodium instead! It's open-source, gives a huge FPS boost and you can modify the Video Settings UI to look more like the traditional interface. And if you want shader support, integrate Iris instead! You can get the huge FPS boost as well as the ability to load almost any shader (plus a hotkey to enable/disable them!)
