by dreamiiing

Improved F3 replaces the vanilla F3 debug screen with a colour-coded, panel-based layout whose sections can be shown or hidden individually.

What it does

Improved F3 is a Fabric mod that reorganises the information shown by the F3 debug screen. Values are grouped under labelled sections for basic information, world details and performance, and each piece can be shown or hidden on its own. Frames per second are coloured by range, with green for 60 and above, yellow for 30 to 59 and red below 30, while light levels use the same colour logic for safety. Semi-transparent backgrounds behind the panels keep the text readable over busy scenery, and a key press toggles the background or the whole overlay.

The settings are stored in a configuration file that saves automatically and persists between sessions. The mod offers several translations and can switch languages from its options. It needs Fabric API on Fabric, runs only on the client, and is published for 1.21.6 – 26.3 with the latest file for 26.3. The code is not open source; the CC0 1.0 Universal dedication places it in the public domain.

Key features

  1. Colour-coded performance

    Frames per second and light levels are shown in green, yellow or red according to set thresholds, so values can be read at a glance.

  2. Semi-transparent panels

    Each section sits on a semi-transparent background that can be toggled, which keeps the debug text legible over varied terrain.

  3. Section modules

    Basic info, world info and performance each form a module, and individual lines inside them can be hidden.

  4. Translated interface

    The screen supports several languages with full translations, including biome names, and the choice is made in the settings.
