Elytra Optimizations

1. 01

   Pre-calculated flight variables

   Several values used by elytra flight are computed once in advance rather than repeated during every tick.

2. 02

   Vanilla-matching behavior

   The optimized math is meant to keep the same flight results as the unmodified game.

3. 03

   Faster per-tick compute

   The author reports about 25 to 35 percent less compute time per tick for the elytra code path.

4. 04

   Public source repository

   The source code is published in a public repository, so the changes can be read and examined.

Who it’s for: Players who fly with elytra on lower-end hardware and want the flight code to take less time each tick. Because the mod is client-side only, it can be added to a single-player world or a client without any server changes.

No Elytras is a server-side only mod, open source under the MIT License, that works on Fabric and Quilt for 1.21 – 26.1, so it changes the server rather than the flight code. Only Elytra Hitbox is a client-side only Fabric mod for 1.21.1 – 1.21.11 that is released under CC0 1.0 Universal and is not open source, and it changes the elytra hitbox rather than the math. Elytra Optimizations is client-side only and open source under the MIT License, with a focus on speeding up the flight calculation itself.

Elytra Optimizations is one of 3,545 Optimization mods on ModsFinder, and one of 2,575 Optimization mods for Fabric. 17,695 mods support Minecraft 1.21.8.
