FastChest

by Domi

With many chests in one room, the frame rate drops, and FastChest addresses that by rendering chests from static block models.

FabricClient-side onlyMIT LicenseOpen source1.15 – 1.21.11

What it does

Minecraft draws each chest individually, so the cost grows with every chest placed. FastChest swaps that drawing for static block models, which the author describes as a fix for storage rooms packed with chests. The gain depends on the chest count: large rooms can roughly double the frame rate, while other causes of slowdown are not touched.

The mod is client-side only, so only the client needs it and servers run without it. It requires Fabric API and is published for Fabric alone, across 38 release versions, 1.15 – 1.21.11, under the MIT License, and the code is open source. Fabric builds for 1.21.11 currently use the 1.6+1.21.9 file, dated 2025-12-10.

Key features

  1. Static chest models

    Chests are drawn from static block models instead of being rendered one by one in the world.

  2. Frame rate in storage rooms

    The drawing change is aimed at rooms holding many chests, where rendering costs are highest.

  3. Vanilla chests only

    Only the vanilla chest, trapped chest and ender chest are handled, and chests added by other mods may break.

  4. Resource pack handling

    Packs that overwrite chest blockstate files conflict with the mod until those files are removed from the pack.

Questions

Does FastChest need Fabric API?

Yes. Fabric API is a required dependency and must be installed alongside FastChest on Fabric.

Can FastChest run alongside a shader or performance setup?

The author states that FastChest works with common rendering and optimization setups, and that it only affects vanilla chests.

Why does a resource pack break chests with FastChest?

Some packs overwrite the chest blockstate definitions. Removing the chest, ender chest and trapped chest blockstate files from the pack's assets folder lets it work with the mod.

What the author says

If your storage room contains a lot of chests, you have probably noticed how bad Minecraft is at rendering them. The more chests are placed, the lower your FPS go. FastChest helps by removing their dynamic models (aka BlockEntityRenderer) and making them render as static chunk geometry, like most normal blocks. (This…
