ImmediatelyFast Backport

ImmediatelyFast Backport brings immediate mode rendering optimizations inspired by ImmediatelyFast to Minecraft 1.16.5 Fabric.

The mod improves rendering performance by batching draw calls and using more efficient buffer handling to reduce CPU overhead during rendering.

Optimizations

This backport aims to improve the performance of:

Entity rendering
Block entity rendering
Particle rendering
Text rendering
GUI/HUD rendering
Rendering used by other mods

It also includes targeted optimizations for certain vanilla rendering paths where possible.

About the Backport

This project adapts many of the rendering optimization concepts used in modern versions of ImmediatelyFast for Minecraft 1.16.5.

Because older Minecraft versions use different rendering internals, some implementations have been rewritten or adjusted specifically for the 1.16.5 rendering engine and Fabric ecosystem.

Not every feature from the original mod may be included, but the goal is to preserve the most useful optimizations while maintaining stability and compatibility on older versions.

Why?

Many players still use older Minecraft versions like 1.16.5, but optimization support for those versions has slowed down over time.

This project exists to help bring modern rendering optimization improvements back to older versions so players and modpacks can continue benefiting from newer performance work.
