Large chest rooms can drag down frame rate fast, and FastChest Mod targets that specific problem by changing how chests are rendered. Instead of using dynamic chest models, it makes them render as static chunk geometry like most normal blocks. The tradeoff is clear: chest lid animations are removed. For players building heavy storage setups, that makes this a focused performance mod worth considering, especially since the author notes it can be very effective in large storage rooms.
Key Features
- Replaces dynamic chest rendering with static chunk geometry to reduce the rendering cost of many placed chests.
- Applies to chest-heavy storage areas where Minecraft can lose FPS as more chests are added.
- Removes chest lid opening animations as part of the rendering change.
- Works with Sodium and Optifine based on available mod description.
- Is designed to stay compatible with mods and resource packs that do not alter chest definitions, with a noted exception for Vanilla Tweaks Proper Break Particles unless specific chest blockstate files are removed from that pack.

FAQ
What does FastChest Mod actually change?
It changes chest rendering from dynamic models to static chunk geometry. That reduces the rendering overhead of large numbers of chests, but it also removes the chest lid opening animation.
Does FastChest Mod work with Fabric and Forge?
Yes. Available information lists both Fabric and Forge as supported mod types, and the download list includes builds for both loaders depending on the Minecraft version.
Is FastChest Mod compatible with resource packs?
The description says it should be compatible with mods and resource packs that leave chests alone. It specifically notes that Vanilla Tweaks Proper Break Particles is not compatible out of the box because it overwrites chest blockstate definitions, though the description also provides a way to adjust that pack.
