Fastload Mod (1.20.1, 1.20) – Get Into The Game Faster

Fastload is a performance optimization mod that modifies how Minecraft worlds are loaded to significantly speed up loading times, available for Fabric, Forge, and Quilt mod loaders.

Every Minecraft player knows the frustration: you click "Play" on your world, and then you wait. And wait. The vanilla game insists on pre-generating 441 chunks in a square radius around spawn before it even lets you see the world — a process that feels painfully slow, especially on older hardware or heavily modded instances. Fastload tackles this exact bottleneck by fundamentally changing how the game handles that initial chunk loading sequence. With over 11 million downloads on Modrinth, it has become one of the most trusted performance mods in the community, and for good reason. Created by StockiesLad with contributions from JoostMSoftware, AbdElAziz333, and others, Fastload takes a clever approach: instead of waiting for hundreds of chunks to generate before you can play, it loads only the single spawn chunk and handles the rest during early rendering. The result is a noticeably faster path from clicking "Play" to actually playing.

Key Features of Fastload

• Optimized 441 Chunk Pre-Generator — Vanilla Minecraft generates 441 chunks (a 21×21 square around spawn) before letting you into the world. Fastload removes this bottleneck entirely by syncing chunk generation with chunk rendering. Instead of front-loading all that work, it loads only the spawn chunk first and fills in the surrounding area as the renderer catches up, dramatically cutting the time between clicking "Play" and actually being in-game.
• Cancellable Loading Screens — Have you ever been stuck on a loading screen and just wanted to back out? Fastload replaces the default loading screens with its own configurable implementation that lets you cancel them. This is particularly useful when loading into large or complex worlds where you might change your mind or need to adjust settings before committing to the load.
• Pre-Rendering Phase — Fastload introduces a configurable pre-rendering phase that allows visual rendering to begin immediately rather than waiting until the player spawn packet is fully received. This means you start seeing the world being built around you sooner, which both feels faster and actually is faster in practice. The configurable nature lets you fine-tune how aggressively this kicks in.
• Multi-Loader Support — The mod runs on Fabric, Forge, and Quilt, making it accessible regardless of which mod loader you prefer. This cross-platform availability is a significant advantage because many performance mods are limited to a single loader, forcing players to choose between optimization and their preferred modding ecosystem.
• Client and Server Optional — Fastload works in both client-side and server-side environments, and neither is required. You can install it on just your client for singleplayer benefits, or on a server to speed up world loading for all connected players. This flexibility makes it easy to add to any setup without worrying about compatibility requirements.
• Lightweight and Focused — Rather than trying to overhaul every aspect of Minecraft performance, Fastload focuses specifically on world loading. This targeted approach means it appears to be lightweight and plays well alongside other optimization mods. The mod author specifically recommends pairing it with C2ME for chunk generation optimization and Sodium for chunk rendering improvements.

How to Install Fastload

1. Install your preferred mod loader: Fabric, Forge, or Quilt. Make sure the loader version matches your Minecraft version (1.18.2 through 1.20.1).
2. If using Fabric, also install the Fabric API as it is required by most Fabric mods including many performance mods.
3. Download Fastload for your specific Minecraft version and loader from the official Modrinth page or CurseForge.
4. Place the downloaded .jar file into your .minecraft/mods folder. If the folder does not exist, create it.
5. Launch Minecraft with your mod loader profile and load any world — you should notice the loading time improvement immediately.

Requirements & Compatibility

Pros and Cons

Alternatives to Fastload

• Ksyxis — A minimalist mod that inspired Fastload's approach, reducing the loading radius to skip the 441-chunk pre-generation entirely with a simpler implementation.
• C2ME (Concurrent Chunk Management Engine) — Optimizes chunk generation through multi-threading, making it an excellent companion to Fastload for even faster world loading.
• Sodium — The go-to rendering optimization mod that speeds up chunk rendering, and is specifically recommended by the Fastload developer for the best combined performance.

Frequently Asked Questions

Is Fastload safe to add to an existing world?

Yes — Fastload only changes how the game loads chunks into memory, not how worlds are saved or generated. You can safely install it on an existing world without risking any data loss or corruption. Simply drop it into your mods folder and load your world as usual.

Does Fastload work with Sodium and other optimization mods?

Yes — the mod developer specifically recommends using Fastload alongside Sodium for chunk rendering optimization and C2ME for chunk generation improvements. Because Fastload focuses narrowly on the world loading sequence, it does not conflict with mods that optimize other parts of the rendering or generation pipeline.

Can I use Fastload on a multiplayer server?

Yes — Fastload supports server-side installation and is optional on both client and server. Installing it on a server can speed up world loading for all connected players. It is not required for clients to also have the mod installed, giving server administrators flexibility in their setup.

Is Fastload still being updated?

No — the original developer, StockiesLad, has publicly announced a step back from modding as of the last update in August 2023. The mod remains functional for Minecraft versions 1.18.2 through 1.20.1, and the open-source codebase on GitHub is available for community members willing to continue development.

Will Fastload cause chunks to load incorrectly or show visual glitches?

No — Fastload does not skip chunk generation, it simply changes when chunks are generated relative to the rendering cycle. Instead of pre-loading all 441 spawn chunks before showing you the world, it loads the spawn chunk first and fills in the rest during early rendering. You may briefly see chunks populating around you as you first enter a world, but all terrain generates correctly and completely.
