Epitaph Optimizer
A lightweight client-side Fabric mod for Minecraft 1.21.11 that automatically applies performance-friendly video settings on startup — the same ones you'd set by hand in Video Settings, just without having to redo it every time.
The mod uses no mixins and doesn't touch game logic, netcode, or the rendering pipeline, which makes it safe to use alongside Sodium, Lithium, Iris, FerriteCore, Voxy, Krypton, and ImmediatelyFast.
What gets tweaked automatically
- Particles → Minimal
- Entity shadows → disabled
- Ambient Occlusion (smooth lighting) → disabled
- Clouds → Fast
- Leaves → fast/cutout (opaque instead of see-through)
- Biome blend radius → 0
