What does it do?
When you hit an end crystal, Minecraft normally waits for the server to remove it before you can place the next one.
On higher ping that wait is easy to feel. Marlow's Crystal Optimizer removes the crystal on your side the moment you
hit it, so you can place your next crystal straight away.
Fabric and NeoForge
| Mod loader | Minecraft versions |
|---|---|
| Fabric | 1.19 - 26.3 |
| NeoForge | 1.20.4 - 26.3 |
On Fabric you also need Fabric API.
Optional mods
- YetAnotherConfigLib adds an in-game settings screen.
- Mod Menu (Fabric only) shows the update badge and opens the settings screen
from the mod list. On NeoForge, both are in NeoForge's own mod list.
