FYI: This can be imported into curseforge, there will also be a barebones version for just the mods and shaders for non curseforge users.
Supremely Optimized has mods that mainly focus on faster performance,faster world loading, faster everything!This is the last modpack you will ever need, its relatively light at 33-34 mods.
The main mods that everybody knows are:
-Sodium
-Iris Shaders
-FerriteCore
-Entity Culling
-LazyDFU
-Starlight
New world generation speeds on Vanilla Minecraft vs Supremely Optimized
Vanilla: 19.5 Seconds Supremely Optimized: 5.59 or 5.6 Seconds
This all depends on settings but the vanilla settings were default and the supremely optimized ones are configured to my use cases.
