ImmediatelyFast – a mod for Minecraft

What does ImmediatelyFast do?

ImmediatelyFast optimizes rendering operations that are often performed when displaying Minecraft interfaces and dynamic visual elements. Its purpose is to reduce the cost of personnel training.

What transactions are affected

The game simultaneously draws HUD elements, text, particles and other objects that change from frame to frame. For some of them, the standard rendering path creates unnecessary computations. ImmediatelyFast changes the execution of these operations to free up CPU and GPU time. This is not a set of shaders and not a server tic acceleration system.

Where to look for an effect

Visually, the mod is usually almost invisible: the blocks and game rules remain the same. Differences can occur in multi-function interfaces, effects-rich scenes, and machines with limited performance. The result depends on the video card, the game version, settings and other graphic modifications.

How to compare the results

Make two measurements with the same drawing range, the same resource pack and without changing other modes. Look not only at the average FPS, but also at the rare sharp frame delays. If Sodium or Iris is used, check separately if the combination is supported in the selected releases.
