Spectrum Patch with TCLayer

by WeakyStar

Spectrum Patch with TCLayer is a Fabric optimization add-on for Spectrum that cuts the frame rate drops players see near water.

FabricClient or server, optionalMIT LicenseOpen source1.20.1

What it does

The patch targets a lag problem tied to Spectrum's Ring Aerial Grace ring. Near water, the ring's trinket checks run an expensive fluid raycast, and this patch changes that path so frame rate no longer falls sharply in those spots. The fix is aimed at the trinket checks that pair with Trinkets Compat Layer Accessories, so the performance gain applies where that pairing is in use.

Spectrum must be installed, because it is a required dependency and the patch only modifies its behavior. The patch is built for Minecraft 1.20.1 alone, with Fabric Loader as the only supported loader. Players install Fabric Loader, add the mod and Spectrum to the mods folder, and launch the game.

Either side can run the patch, and neither needs it, so it can be added to a single-player client, a server, or both. Files are published for 1.20.1 only, with version 1.0.0 dated 2026-05-20, which is also the first and last update. The code is under the MIT License and is open source, with public source code and an issue tracker.

Key features

  1. Water-side frame rate fix

    Cuts the FPS drops that occur near water when Spectrum's Ring Aerial Grace is equipped.

  2. Cheaper trinket checks

    Changes the expensive fluid raycast that runs during trinket checks so it costs less per tick.

  3. Trinkets Compat Layer pairing

    The fix targets the trinket path used together with Trinkets Compat Layer Accessories.

Questions

Does Spectrum Patch with TCLayer need Spectrum?

Yes. Spectrum is a required dependency, and the patch changes how Spectrum's trinket checks behave, so it has no effect without it.

Can the patch run on a server?

Yes. Either side can run it, and neither needs it, so a server can run it alone, a client can run it alone, or both can have it installed.

Which Minecraft versions does the patch support?

Only 1.20.1. Files are published for that version alone, and version 1.0.0 is the current release.

Does the patch need Trinkets Compat Layer Accessories?

The fix is aimed at the trinket path used with Trinkets Compat Layer Accessories, so that pairing is where the change applies.
