Mod ImmediatelyFast

ImmediatelyFast, faster Minecraft rendering

ImmediatelyFast is an open source optimization mod for Minecraft Java Edition that improves immediate mode rendering without changing gameplay. Its custom buffering system batches draw calls and sends data to the GPU more efficiently, helping scenes feel smoother when the CPU is the performance limit.

The mod targets entities, block entities, particles, text, maps, GUI and HUD rendering, including visual elements added by other mods. It is lightweight, designed for compatibility with modpacks, and available for Fabric, Forge, NeoForge and Quilt on supported versions. On a busy Minecraft server, it can improve frame rates when many creatures, chests, maps or interface elements are visible. BoxToPlay makes this client focused enhancement easy to enjoy alongside your server experience.
