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.

Frequently Asked Questions

Does Marlow's Crystal Optimizer need to be installed on the Minecraft server?

No. Modrinth marks Marlow's Crystal Optimizer as unsupported on the server side. Install it only in your local Minecraft mods folder. Your server can remain unchanged unless the mod page lists an additional dependency.

Which version and loader does Marlow's Crystal Optimizer require?

Use a file for fabric, neoforge and your exact Minecraft version. Supported versions include 26.3, 26.2, 26.1.2. Files for different loaders are not interchangeable.

Marlow's Crystal Optimizer is not working – what should I check?

First check the Minecraft version, loader version and required dependencies. Put the .jar file in your local .minecraft/mods folder and remove older duplicates. Because this mod is client-side, adding server RAM will not fix it.
