Client-Movement
Fabric mod for Minecraft 26.1-26.1.1 making sprinting and poses entirely client-sided with no server interference. This greatly reduces the amount of movement glitches and inconsistencies for players with high ping and gets rid of the ancient FOV-wobble glitch (MC-4098).
This mod could possibly get flagged by certain AntiCheats and might be seen by some as an unfair advantage (you don't lose sprint from hitting non-player entities anymore, but that is purely visual when holding sprint and doesn't apply for PvP), so use at your own discretion.
