ImmediatelyFast – FPS Boost Mod For Minecraft 1.20.4, 1.19.4


ImmediatelyFast 1.20.4-1.19.4 is an open source Fabric mod that improves client rendering performance in immediate mode. It is designed to be lightweight and compatible with other mods. This makes it an ideal choice for modpacks or as a replacement for other FPS boosters such as Exordium or Enhanced Block Entities.

By optimizing parts such as Entities, Block entities, Particles, Text rendering and GUI/HUD, as a rule, the frame rate per second should be 2 times higher on loaded servers, and can also be up to 4 times higher in cases where there are many objects.
