Nefat

Nefat 1.0.1-beta (English)
Performance
More FPS than Sodium: 8.8% more on average in the same tests, and up to 24% more in scenes with many items or with rain.
Faster terrain textures: filtering takes 4 texture reads instead of 9, with the same quality.
Faster items and entities: they are written one face at a time instead of one vertex at a time.
Less stutter while the world loads: chunks and light updates that arrive all at once are spread over several frames; the worst stutter drops from ~187 ms to ~70-110 ms.
Compatible with Sodium: when Sodium is installed, Nefat turns off the part that would conflict with it.
Water
Small waves moving in every direction, without looking like a current.
Brighter turquoise colour, sun glitter, and light shining through the wave crests.
Foam along shores, walls and blocks sticking out of the water.
Ripples when you get into the water or something falls in, and a V-shaped wake when swimming or rowing a boat.
Glossy blocks (new)
Quartz, diamond, emerald, polished stones, glazed terracotta, obsidian and metals (iron, gold, copper, netherite) get a waxed finish that reflects the sun, the sky and the world.
No PBR resource pack needed.
New “Glossy blocks” option to turn it on or off.
Nether
No longer dark: a glowing haze in each biome’s own colour, orange in the Nether Wastes and teal in the Soul Sand Valley.
Glowstone and lava glow brighter.
New “Nether brightness” option.
Sky and lighting
The sun is a small, realistic disc instead of a huge white ball.
New smooth, steady bloom: no circles around lights and no flickering.
The vignette is softer and now off by default.
Varied sunsets.
Weather-based fog, sunbeams through the clouds after rain, and rainbows.
Cherry grove
The pink haze is much lighter and no longer hides the view or the sun.
It no longer shows up in caves under a cherry grove.
Fixes
Grain in closed rooms when sunlight comes in.
False sky reflections on glossy floors under a roof.
Crash when changing the shader quality.
Pitch-black caves.
Brown stains in water reflections.
