lithium VS sodium

Lithium: General performance boost. (not updated)

For Minecraft specifically, regardless of hardware and OS, you should be using Sodium and Lithium. These are third-party mods that fix a ton of performance issues - they make a huge impact especially on lower-spec'd machines.

i can confirm what mrspinn has posted but I would use rubidium and not magnesium(both ports of sodium, just a different authors on the ports.), this works with magnesium/rubidium extras as well for things like a better zoom function(runs off the sodium base so both ports are fine). Then if you'd like shaders with this you can use oculus(port of iris), this works with optifine shader packs. Road runner is good for cleaning up a lot of the overhead in things like game physics, AI, block ticking, etc (port of lithium, don't know why this one didn't keep the chemical name). Starlight again is good at what it does, even to the point of being integrated into papermc(which is why it's on their github and not the spottedleaf's personal anymore), don't know if you've sent much time around plugin servers. I also then use Ferritecore this greatly helps bring down memory requirements of the pack(I can run on 4gb, given I have fairly fast memory).

Lithium (further optimization, also by Sodium devs)

Sodium Phosphor Lithium also get iris but I don't have download link

Here’s a page on the config file if you want more info:github.com/CaffeineMC/lithium-fabric/wiki/Configuration-File

Are you using Optifine? That's the largest contributor to graphical issues. Instead, try Sodium and Lithium.

It's just that. It's a free and open source optimization mod that aims to improve fps, and fixes other issues. Along with that, Sodium is free and open source (available on GitHub). By default, Sodium does not provide shader support, and shader support can be done with Iris (Iris is also open source and free as well). But if you want to optimize your fps even more, you can bring in Lithium and Starlight (Lithium targets overall optimization, like the AI and other stuff without breaking the game, and Starlight is a complete rewrite of the vanilla lighting engine to be even more faster and fixes so much stuff with the lighting engine). And you can tack on more mods, like FerriteCore, Enchaned Block Entities (EBE) in order to optimize other parts of the game

[22:52:47] [Render thread/WARN]: If the game crashes immediately after this point, please make a bug report: https://github.com/CaffeineMC/sodium-fabric/issues

I googled "fabric crashes with falling block" and found this GitHub Issue in the Sodium Repo. Solution: install Indium, because continuity relies on it to bridge over to sodium.

It`s Indium. https://github.com/CaffeineMC/sodium-fabric/issues/1324

if https://github.com/CaffeineMC/sodium-fabric/issues/1006 is what you are talking about, it is an upstream issue for any forge port of the sodium mod

Wow, a reasonable criticism! According to this issue, transparency sorting hasn’t been implemented, and so the behavior is inconsistent. Surprised to see a pull request linked that had fixed it, but was never merged and is now incompatible. Definitely affects users who have farms and stained glass builds though!

The problem with the multithreaded version of Optifine is that OpenGL doesn't officially support multithreading (at least not with older versions of OpenGL; Sodium (for modern versions) uses a "multidraw" function to get up to 10x the FPS but also uses OpenGL 4+, and even then it has issues on many drivers. Note that using such modern features would require a "core profile", precluding the use of all legacy fixed-function methods so the entire renderer would have to be rewritten).
