ImmediatelyFast Reforged (Unofficial)
by CCr4ft3r
On the client, ImmediatelyFast Reforged reworks immediate mode rendering through a custom buffer implementation, bringing the Fabric mod ImmediatelyFast to Forge.
What it does
The mod speeds up immediate mode rendering, the path that draws block entities and text. Its changes to the vanilla rendering code are targeted: where the original code runs in an order that slows drawing, the port reorders it, and it replaces parts of the rendering code with more efficient implementations. Draw calls send their data to the GPU through a leaner upload method. The mixin injection points match SRG names on Forge.
The port keeps the optimizations of the original Fabric mod, and the author states that its performance equals that of the Fabric version. The mod is built to interfere with other mods as little as possible and is described as a good fit for modpacks. ImmersivePortals benefits a great deal from immediate mode rendering improvements. Support for OptiFine is not part of the release, and the author does not plan it here. Since it runs on the client only, it is installed on the client alone.
Key features
Immediate mode rendering
Immediate mode draw calls go through a custom buffer implementation that batches work before it reaches the GPU.
Block entity and text rendering
Targeted changes speed up how block entities and text are drawn, parts of the code path that vanilla reorders.
Adapted mixin injection points
Class references and injection points are adapted to SRG names, and some embedded libraries were removed in favor of default mixin annotation classes.
Limited compatibility modes
Some compatibility modes were removed, and the mod is structured to touch other code as little as possible.

Use cases
Who it’s for: Players on Forge 1.19.2 who want faster rendering on the client, and modpack authors who need a rendering optimization that stays out of other mods' way.
How it compares
Dynamic FPS Reforged is a client-side Forge mod for 1.19.2 – 1.19.4, open source under the MIT License, and it targets frame rate rather than rendering internals. Mineshot Reforged is also client-side only, but it is built for Forge 1.16.5 and is not open source. Both differ from this mod in version range and purpose.
