ImmediatelyFast Mod Download for Minecraft 26.3 Fabric: Fix Laggy Text and Menus
Quick answer: ImmediatelyFast is a free client-side mod that speeds up how Minecraft draws text, items, and menus. The latest release is ImmediatelyFast 1.17.1 for Minecraft 26.3, and the download below is the Fabric build, verified on Modrinth today. It fixes stutter when you open chests, read signs, or scroll through inventory. Install Fabric for 26.3 plus Fabric API, drop the .jar into your mods folder, and launch the game. Players still on Minecraft 1.21.1 should use the 1.6.15 build instead, which is the latest release for that version.
Open a chest in a busy base and watch what happens. The game pauses for a beat, the items pop in one by one, and the frame rate dips until the inventory settles. That hitch comes from how vanilla Minecraft draws text and item icons: one draw call at a time, with no batching, in code that was never written for a screen full of enchanted gear. ImmediatelyFast rewrites that part of the renderer, and the difference is obvious the first time you open a shulker box.
The mod comes from developer RaphiMC and has more than 130 million downloads on Modrinth. It does one job and it does it well: it makes the parts of the game that draw text and items run faster. It adds no blocks, no items, and no settings you need to learn. It is a client-side mod, so it works in singleplayer and on any server, and it will not change how anyone else sees the game.

What ImmediatelyFast actually does
Vanilla Minecraft renders text and items in a slow, piecemeal way. Every line of chat, every item name in a tooltip, every sign in view, and every icon in a chest inventory gets drawn with its own set of draw calls. On a modern GPU that is still fast enough most of the time, but it creates spikes: the game does a burst of work in one frame, the frame takes too long, and you feel a stutter.
ImmediatelyFast batches that work. It groups text glyphs and item icons into fewer draw calls, caches glyph atlases so the same characters are not re-rendered from scratch, and skips work for text that is off-screen or hidden behind other UI elements. The screen looks identical. The same text, the same icons, the same colors. The game just draws them with far less effort.
The effect is strongest in three places. First, large inventories: chests, shulker boxes, and creative menus with hundreds of item icons. Second, text-heavy screens: chat, signs, books, and tooltips. Third, HUD-heavy moments: scoreboards, boss bars, and item frames in a busy base. If your game stutters when you open a chest but runs fine when you are walking around, ImmediatelyFast is aimed at your exact problem.
How much faster will your game run
There is no honest single number. The gain depends on how much text and item rendering your screen is doing at any moment. In a quiet field with an empty hotbar, ImmediatelyFast changes almost nothing, because there was no text or item work to speed up. In a storage room with 50 chests and item frames on every wall, the difference can be large: inventories open instantly, tooltips appear without a hitch, and the frame rate stops dipping every time you scroll.
The clearest sign it is working is how inventories feel. Open a double chest full of enchanted books and scroll through it. In vanilla, the scroll stutters as new icons render. With ImmediatelyFast, the scroll is smooth from the first frame. The mod does not raise your average frame rate in the same way Sodium does, because it targets a different bottleneck. It removes the spikes, and a game without spikes feels faster even when the average frame rate barely moves.
Compatibility: versions, loaders, and what it needs
| Minecraft version | Latest ImmediatelyFast | Loaders |
|---|---|---|
| 26.3 | 1.17.1 (release) | Fabric, Forge, NeoForge |
| 1.21.1 | 1.6.15 | Fabric, Forge, NeoForge |
| 1.20.1 | 1.2.21 | Fabric, Forge |
The download on this page is ImmediatelyFast 1.17.1 for Minecraft 26.3 on Fabric. Forge and NeoForge builds of the same version are on the same Modrinth project page if you play on a different loader. The Fabric build needs Fabric API installed alongside it.
Read the version table carefully before you download. The mod has two live version lines: 1.17.1 is the build for Minecraft 26.3, and 1.6.15 is the build for Minecraft 1.21.1. They are different files for different game versions. Do not install the 1.21.1 file in a 26.3 mods folder. It will not load. Grab the file that matches the Minecraft version you actually play.
ImmediatelyFast is client-side only, so it works on any server you can join with mods. It does not change gameplay, so server owners have no reason to block it. It also works with Sodium. The two mods target different parts of the renderer and are tested together in most performance packs. For the rendering side of that setup, see our Sodium Mod download and our best performance mods for 2026.
Mods that pair well with ImmediatelyFast
ImmediatelyFast covers text and item rendering. Three companions cover the rest:
- Sodium. Fixes chunk rendering, the biggest single source of frame rate loss. Together they cover both halves of the rendering pipeline.
- Lithium. Optimizes game logic, ticking, and physics, the parts neither Sodium nor ImmediatelyFast touches. See our Lithium Mod download.
- Entity Culling. Skips drawing entities hidden behind walls, which helps in villages and bases full of item frames. See our Entity Culling Mod download.
Start with ImmediatelyFast alone, open a few chests, and feel the difference. Then add Sodium and measure again. Adding one mod at a time is the only way to know which mod gave you what.
How to install ImmediatelyFast
- Install a mod loader for Minecraft 26.3. This download is the Fabric build, so install Fabric for 26.3 from the official Fabric site, plus Fabric API. If you play on Forge or NeoForge, grab the matching build of ImmediatelyFast 1.17.1 from Modrinth instead. Our Fabric install guide walks through the setup.
- Download ImmediatelyFast 1.17.1 using the button above. The file is ImmediatelyFast-Fabric-1.17.1+26.3.jar, about 0.1 MB.
- Open the Minecraft launcher, select the Fabric 26.3 profile, and click Play once so the game creates its folders. Close the game.
- Press Windows + R, type %appdata%\.minecraft\mods, and press Enter. On Mac, open Finder, press Cmd + Shift + G, and enter ~/Library/Application Support/minecraft/mods.
- Move the ImmediatelyFast .jar file and the Fabric API .jar file into the mods folder. Do not unzip either one.
- Launch the game with the Fabric profile. ImmediatelyFast has no menu and no settings screen. If the game loads, it is running.
If the game crashes on launch, the usual cause is a version mismatch: a 1.21.1 jar in a 26.3 mods folder, or a missing Fabric API. Check the file names first. Our mod crash troubleshooting guide covers the rest of the common cases.
Is ImmediatelyFast safe to download
Yes, when you get it from Modrinth. ImmediatelyFast is open source, its code is public, and the Modrinth listing is maintained by the developer. Download counts and version history are visible on the project page, which is how you confirm a file is genuine. Never download ImmediatelyFast from a re-upload site or a “free mods” aggregator. Those copies are where malware hides, and they are often outdated versions with the version number changed.
The download button on this page points directly at the Modrinth CDN file for ImmediatelyFast 1.17.1, Fabric, Minecraft 26.3. It starts the .jar download immediately, with no installer, no extra software, and no account needed.
Frequently asked questions
Is ImmediatelyFast free?
Yes. ImmediatelyFast is free and open source. The developer accepts donations, but no feature is locked behind a payment.
Does ImmediatelyFast work on Minecraft 26.3?
Yes. Version 1.17.1 is the build for Minecraft 26.3, on Fabric, Forge, and NeoForge. Download the file that matches your loader.
What if I still play on Minecraft 1.21.1?
Use version 1.6.15, which is the latest release for 1.21.1. It is on the same Modrinth project page. Do not mix the two lines: the 1.17.1 file will not load on 1.21.1, and the 1.6.15 file will not load on 26.3.
Does ImmediatelyFast increase FPS?
It removes stutters from text and item rendering rather than raising your average frame rate. In a storage room or a text-heavy screen, the difference is obvious. For raw FPS, install Sodium alongside it.
Does ImmediatelyFast work on servers?
Yes. It is client-side, so it works on any server you can join with mods. It does not change gameplay, so server owners have no reason to block it.
Do I need Fabric API?
Yes, for the Fabric build. Install Fabric API in the same mods folder. The Forge and NeoForge builds have their own requirements listed on the Modrinth page, so check the file page for the build you download.
Verdict
ImmediatelyFast is a small mod with a narrow job, and it does that job well. It will not fix a slow computer, and it will not raise your frame rate in an empty field. What it does is remove the exact stutter that annoys players who live in storage rooms, shops, and text-heavy servers: chests that open instantly, tooltips that appear without a hitch, and menus that scroll smoothly. It is a single small file, it takes two minutes to install, and it is free. If you play on 26.3 and your inventories feel sluggish, install it. If you are still on 1.21.1, grab the 1.6.15 build for that version instead.
