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 and your exact Minecraft version. Supported versions include 26.2, 26.1.2, 26.1.1. 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.
