OmniPerf - The 1.21 Performance Fix
Minecraft often drops frames in places you wouldn't expect. OmniPerf is a lightweight mod that cleans up the background rendering to make your game feel much smoother.
What it does: The mod optimizes how the engine handles text rendering and UI updates. This might sound small, but it prevents the "micro-stutters" that happen in busy lobbies or when playing heavy modpacks. It streamlines the internal frame-timing to make sure your CPU and GPU work together more efficiently.
Features:
-
FPS Boost: Improved frame-timing logic that gives you a noticeable jump in performance. Just check your F3 screen after launching.
-
Integrated Zoom: A built-in zoom key (fully bindable) that stays smooth even while zooming in.
-
Fully Compatible: Works perfectly alongside Sodium, Iris, and other major performance mods.
Installation: Just drop the .jar file into your mods folder. No complicated config needed—everything is active the moment you start the game.
