Realism Refreshed

Realistic survival that doesn’t bog your PC down.
Sodium, Lithium, Iris, Distant Horizons, FerriteCore, ImmediatelyFast - all keep your FPS up, even with utterly ridiculous render distances and shaders enabled.
Tough As Nails - adds thirst and temperature to the game. Serene Seasons - realistic weather cycles.
Sound Physics, Presence Footsteps, Ambient Sounds - all make the game feel more alive.
Tectonic, Continents, YUNG's temples/caves/monuments, Incendium, Nullscape - all make exploration feel like something big and realistic.
Fresh Animations - plus improved mob movement make the game feel more alive. Kappa/Photon shaders, Dramatic Skys, Particle Rain - all make the game look utterly bonkers without making it run like a slideshow.
Macaw's tools - if you want to build things, they're the way to go.
Simple Voice Chat - if you're playing with others.
300+ mods - all of which have been tuned for performance, then realism. No bloat, no broken balance - just the vanilla game pushed hard to be more realistic and alive.
