Addoners Optimizers

Once every second, Addoners Optimizers reads the player's frame rate as a rolling average and switches between one of three optimization levels. Level choice follows the measured FPS: a minimal level above 80 FPS, moderate reductions between 50 and 79 FPS, and stronger reductions aimed at frame stability on weaker systems. Changes made to render distance, particle settings, smooth lighting and shader quality are spaced by a 3-second cooldown, which limits rapid back-and-forth switching.

Once a profile is set, the optimizer starts automatically when Minecraft launches, so no command or button press is needed during play. Setup still requires a manual step, and the performance gain varies with hardware, render distance and shader configuration. Testing was done mainly on systems running Fabric with Sodium-based rendering under different render distances and shader setups.

Addoners Optimizers is built for Fabric and runs on the client only, so servers do not need it. It is published for Minecraft 26.1.2 alone, with the latest file 1.5.0 dated 2026-04-14. The project is open source under the GNU General Public License v3.0 only, and its source code is public.
