phosphor-fabric VS sodium-fabric

Phosphor (another optimization mod by the Sodium devs, targeting the built-in lighting system)

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

There’s lots of lightweight shader packs designed for low-end PCs. For an optimized, smooth shader experience I’d recommend installing Fabric, Sodium, Lithium, Phosphor, and Iris Shaders.

I would suggest you to use Sodium or Iris - Overall Performance Improvement / Iris If You Wanna Use Shaders Too Lithium - Improve CPU Usage LazyDFU - Launch Game Faster Phosphor - Improve Light Engine Hydrogen - Reduce Memory Usage

Low performance is to be expected with your config. You can try to install these performance mods for minecraft : * Iris that contains Sodium * Sodium, don't use it with iris, it already has sodium. * Lithium * Phosphor

Lithium is only for Fabric. There's also Phosphor to improve lighting performance.

You can get better performance and retain vanilla features by using Fabric with phosphor and lithium.

for newer versions Sodium+Lithium+Phosphor (+aditionally hydrogen)

Please use the Randon World Format for it uses less RAM and uses less file space and please use the Lithium Lighting Engine for the same reason.

[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).
