Mod Sodium (1.20.4) - increases your FPS

Sodium Mod (1.20.4) is a free and open source rendering engine replacement for the Minecraft client that significantly improves frame rate, reduces microstuttering, and fixes graphical issues in Minecraft.

Features.

The modern OpenGL rendering pipeline for rendering chunks uses multi-render techniques to significantly reduce CPU load (~90%) when rendering the world. This significantly improves frame rates on most computers that aren't cluttered by GPUs or other components, and even if the GPU can't keep up, the CPU can work on other rendering tasks while waiting, resulting in more consistent frame times. Vertex data in render chunks is more stable.

Vertex data in render chunks is more compact, reducing video memory and bandwidth requirements by approximately 40%.

Adjacent chunk updates now take advantage of multi-threading, which significantly reduces the latency spikes that occur when chunks need to be updated.

Early in the rendering process, the faces of blocks that are not visible (or facing away from the camera) are eliminated, so there is not a lot of geometry created which is processed by the GPU and immediately discarded. For integrated GPUs, this significantly reduces memory bandwidth requirements and provides acceleration even when bound to the GPU.

Extensive chunk loading and block rendering optimizations allow for significantly faster chunk loading and lower frame rates.

p>Numerous optimizations for vertex plotting and matrix transformations that significantly speed up the rendering of block-based entities, mobs and items.

Many improvements to memory management and object allocation, reducing memory consumption and lag caused by the garbage collector.< /p>

Many graphical fixes for smoother lighting effects.

Smooth lighting of liquids and other special blocks.

Smooth blending of blocks and liquids in the biome, which greatly improves the quality of graphics and significantly reduces computation.

Faster texture updating on most hardware (especially AMD cards), since animated textures that are not rendered in the world are not updated.

... And so on, and the list continues to be written after its initial release.

The mod boasts wider compatibility with the Fabric mod ecosystem than other mods, giving you the feeling of a true blocky game without compromising the look of the game.

If you're migrating from Optifine, you can expect significant performance improvements over Optifine, but you'll be missing out on some smaller features while the Fabric community builds other free and open-source alternatives. Sodium and Optifine are incompatible with each other. You'll have to choose one or the other.

There are other comparisons for different hardware configurations:
