FluidCam

FluidCam is a lightweight client-side Fabric mod that improves the feel of camera and mouse movement. In vanilla Minecraft, camera rotation snaps instantly to wherever your mouse moves, which can feel jarring and rough — especially during fast-paced PvP or when trying to aim precisely.
FluidCam fixes this by adding smooth camera interpolation. Instead of the camera jumping directly to your mouse position, it glides naturally and fluidly, giving your gameplay a much more polished and cinematic feel without sacrificing responsiveness.

Smooth camera interpolation for fluid mouse movement

Client-side only — works on any server
