Overview
ImmediatelyFast is a performance mod created by RaphiMC. Optimizes immediate-mode rendering used by HUDs, GUIs, text, and item displays for a notable FPS boost. As a performance mod it concentrates on frame rate, loading times, and memory use, and it has been downloaded around 30 million times, which puts it among the options players reach for in this space.
ImmediatelyFast is built for players who want a low-risk rendering speedup that stacks with other mods. It optimises the game's immediate-mode rendering paths, improving frame times with no visible change and broad compatibility. It is approachable enough to drop into a world and use right away, with little setup required.
The mod is available for Forge, Fabric, and NeoForge, so it fits a range of modpacks and launchers. It currently supports Minecraft 1.20.1, 1.20.4, and 1.21.1, spanning the 1.20.1 to 1.21.1 releases. It is a client-side mod, which means you can add it to your own game for personal benefit even when the server you join does not run it.

How to install ImmediatelyFast
ImmediatelyFast supports Forge, Fabric, and NeoForge; pick one loader (you cannot mix them) and install it for your chosen Minecraft version. It is built for Minecraft 1.20.1, 1.20.4, and 1.21.1, so make sure your profile uses one of those versions.
- 1Choose and install one mod loader from Forge, Fabric, and NeoForge for a Minecraft version this mod supports (1.20.1, 1.20.4, and 1.21.1).
- 2Check the download page for any required libraries. ImmediatelyFast lists no hard dependencies here, but it is always worth confirming for your exact version.
- 3Drop the ImmediatelyFast .jar file into your instance's mods folder. On a server, place it in the server's mods folder instead, and each player who wants it adds it to their own client.
- 4Launch the game with that loader profile and confirm ImmediatelyFast appears in the in-game mods list; if it does not load, re-check the loader, the Minecraft version, and any library requirements.
Supported Minecraft versions: 1.20.1, 1.20.4, and 1.21.1. Always download the build that matches your version exactly, as mod files are version-specific.

ImmediatelyFast works particularly well alongside Sodium and Entity Culling. Because it ships for both Fabric and Forge-family loaders, it slots into most popular modpacks regardless of which side they are built on.
As a performance mod, ImmediatelyFast is meant to improve how the game runs rather than change gameplay, so it is generally safe to combine with other optimisation mods.
If you are comparing options, similar mods include Enhanced Block Entities and FastQuit. They cover comparable ground, so the right choice usually comes down to your loader, version, and the rest of your pack.
