Chloride (Embeddium++/Sodium++) Mod (1.21.1, 1.20.4) – Customize FPS

Chloride is a performance and quality-of-life addon mod that enhances Embeddium and Sodium with entity culling, visual tweaks, and dozens of customization options for Minecraft Forge and NeoForge players.

Minecraft's rendering engine has always been a bottleneck. Sodium and its Forge port Embeddium solve the biggest chunk of that problem, but they intentionally keep their scope narrow — core rendering only. That leaves a gap: players still deal with unnecessary entity rendering in the distance, recipe overlay clutter from JEI or REI, and a lack of visual customization options like fog control or darkness settings. Chloride fills that gap precisely. Created by SrRapero720, this addon has earned over 12 million downloads by bundling the performance tweaks and quality features that Sodium deliberately leaves out. Think of it as the seasoning on top — fittingly named after NaCl (sodium chloride).

Key Features of Chloride

• Entity Distance Culling — One of the biggest FPS drains in Minecraft comes from rendering entities that are too far away to matter. Chloride stops rendering and ticking entities and block entities beyond a configurable distance, which can dramatically reduce lag in entity-heavy areas like farms or mob spawners. It also includes a whitelist system so important entities like the Ender Dragon or Ghast always render regardless of distance.
• Leaves Culling — Dense forests can tank your frame rate because the game renders every single face of every leaf block, even the ones completely hidden behind other leaves. Chloride intelligently reduces the number of rendered leaf faces within groups of the same type, and gives you a slider to control exactly how aggressive the culling is. The result is noticeably smoother performance in forest biomes without visible quality loss.
• True Darkness — Vanilla Minecraft never gets truly dark — even at night or deep underground, there is always a baseline brightness. Chloride adds multiple darkness levels ranging from Dim all the way to Blackness, making caves and nighttime genuinely intimidating. Moonlight and block lights still affect visibility dynamically, so torches and lanterns feel more meaningful when the surrounding darkness is real.
• Hide JEI/REI/EMI Overlay — If you play with recipe mods like JEI, REI, or EMI, you know the item overlay takes up a large portion of your screen at all times. Chloride hides the overlay until you actually type something in the search bar, keeping your screen clean during normal gameplay. A small message reminds you to search when you need the overlay back, so you never lose access to it.
• Built-in Zoom Key — Instead of installing a separate zoom mod, Chloride includes an immediate zoom key with configurable minimum and maximum distances. You can scroll to adjust the zoom level while zoomed in, making it practical for scouting terrain, reading distant signs, or spotting mobs. The feature can be fully disabled if you prefer a dedicated zoom mod instead.
• Borderless Fullscreen — Vanilla Minecraft's fullscreen mode causes black screens when alt-tabbing and slow window switching. Chloride adds a borderless fullscreen option that supports quick tab switching and picture-in-picture, eliminating the dreaded black screen problem. You can even bind the F11 key to toggle borderless mode instead of traditional fullscreen.
• FPS & Performance Display — Chloride includes a customizable HUD that shows your average, minimum, and current FPS alongside memory usage and GPU usage percentages. Unlike the debug screen (F3), this display is compact and can be positioned anywhere on screen — even above your hotbar for at-a-glance monitoring during gameplay.

2. Install Embeddium (for Forge/NeoForge) or Sodium — Chloride is an addon and requires one of these as a base.
3. Download the correct Chloride version for your Minecraft version and mod loader from the download section below.
4. Place the downloaded .jar file into your .minecraft/mods folder.
5. Launch Minecraft and open the Sodium/Embeddium video settings menu — Chloride's options will appear as additional tabs and toggles.

Pros and Cons

Alternatives to Chloride

• Sodium Extra — A Fabric-side addon for Sodium that adds similar visual toggles and performance features, ideal if you play on Fabric instead of Forge or NeoForge.
• Entity Culling — A dedicated entity culling mod that uses async path-tracing to skip rendering of hidden entities, available for both Fabric and Forge.
• Embeddium — The Forge/NeoForge port of Sodium that serves as the required base for Chloride, delivering core rendering performance improvements on its own.

Frequently Asked Questions

Is Chloride compatible with OptiFine?

No — Chloride is built as an addon for Embeddium and Sodium, which are fundamentally incompatible with OptiFine. You need to choose one rendering pipeline or the other. Chloride combined with Embeddium covers most of the features OptiFine provides, including zoom and performance improvements.

Does Chloride work on Fabric?

No, Chloride is only available for Forge and NeoForge. Fabric players should look at Sodium Extra, which provides a similar set of addon features for the Fabric version of Sodium.

Do I need Embeddium or Sodium installed to use Chloride?

Yes — Chloride is an addon mod, not a standalone performance mod. It requires either Embeddium (on Forge/NeoForge) or Sodium as a base. Without one of these installed, Chloride will not load.

Will Chloride conflict with other performance mods?

Generally no, as long as the other mods do not overlap with Chloride's specific features. Entity culling mods may conflict since Chloride includes its own entity distance culling. It is best to disable overlapping features in one mod when running both together.

Can I customize which Chloride features are enabled?

Yes — every feature in Chloride can be individually toggled on or off through the Embeddium/Sodium settings menu. You can enable entity culling while disabling true darkness, or use only the zoom key and FPS display. The settings locker feature even lets you lock specific settings to prevent accidental changes.
