KNOWN ISSUE: DOESN'T WORK ON 1.21.2+
I'm currently trying to get a fix for that.
Optimizes Elytra's janky math code by pre-calculating some variables and other stuff. It gains roughly 25-35% faster compute timing per tick while still maintaining vanilla parity (should be even better on lower-end hardware!).
Performance:
Every ~millionth tick of nonstop flying with the Elytra (equivalent to almost 14 hours) Minecraft computes ±300 FPS more (not that impressive but still something!). Go to gallery for a more in-depth explanation.
Dependencies:
- Fabric loader installer (version 0.16.14+) - https://fabricmc.net/use/installer/
- Fabric API (any version that supports Minecraft version 1.21.1+) - https://modrinth.com/mod/fabric-api
Credits:
- sebastian - old icon and Neoforge port
- repository for Neoforge https://github.com/BaboboiPR/elytra-optimization-neoforged
Compatibility:
Should work with every other mod.
