More Culling — a technical mod for graphics optimization and significant FPS boost in Minecraft

Minecraft uses basic culling for invisible blocks, but it works in a limited way. The game still renders parts of blocks completely obscured by other structures, inner sides of leaves, or text on signs, even if they physically cannot be seen. More Culling expands this system and removes unnecessary rendering. The result is less GPU load and more FPS, especially in forests, large bases, villages, and at high render distances. 

How More Culling works  

The mod checks if the player can actually see a certain side of a block or model. If not, that part is not rendered. 

For example, if you place several glass blocks close to each other, the vanilla version often continues to render the inner faces. More Culling removes this.

The same works with leaves — in a dense forest, the mod removes parts of models that are covered by other leaf blocks. On weaker graphics cards, this often provides a noticeably more stable FPS.

One of the reasons for the mod's popularity is that almost all features can be individually disabled and configured via the config file moreculling.toml

Where the FPS boost is highest 

The mod does not provide the same result in all worlds.

The biggest difference is noticeable in the following scenarios:

• large forests with a lot of leaves

• bases with glass

• storages with item frames

• server spawns with decorations

• large villages

• high render distance

Demonstration of the mod working in a dense area

If playing in a normal world with an 8-chunk render distance, the boost may be minimal. If using 20+ chunks or resource packs, the difference is felt much stronger. 

When the mod is not needed 

When playing on a low render distance and there are few decorative blocks in the world, the boost will be insignificant.

Also, More Culling will hardly help if the problem is in the CPU, chunk generation, or a large number of mobs. In such cases, other mods will be more useful.

Conclusion 

More Culling solves a specific problem — it removes unnecessary rendering of models and blocks that are invisible anyway. Compared to other similar mods, it works more specifically with blocks, leaves, and decorative elements, rather than with mobs behind walls. The main limitation is that conflicts with graphical mods sometimes happen, so it's worth checking version compatibility for large modpacks.
