FPS Display Doubler
by PaintNinja
FPS Display Doubler is a Forge client-side utility that changes the framerate number shown on the F3 screen, not the rendering speed.
What it does
The mod reports a framerate figure about twice the real one. The author describes the effect as a perceptual algorithm that manipulates visual cues, and the underlying rendering pipeline is left as it is. Because only the displayed value changes, the game does not become faster to run, and the figure should not be read as a measure of performance.
Installation needs Forge only, with no other dependency listed. Only the player's game needs it, and servers run without it. Files are published for Minecraft 1.20.4 only, with 1.0.0 as the latest Forge file. The mod is released under the MIT License and is not open source.
The author notes that adjusting the Max FPS and VSync options in the video settings is recommended, so the doubled number matches the settings the player chose. OpenGL 4.1 or higher is required to run the mod.
Key features
Doubled framerate display
The framerate counter on the F3 screen shows roughly double the measured value.
Perceptual framerate algorithm
The mod describes its approach as a patent-pending algorithm that manipulates visual cues to produce the doubled figure.
Underlying system left unchanged
Rendering and game logic are not altered, only the displayed counter.
Max FPS and VSync guidance
The author advises matching the Max FPS and VSync settings to the doubled number in the video options.
Compatibility
Latest build for each game version and loader.
Only full game releases are shown. This mod publishes no snapshot builds.
Use cases
Screenshots of the F3 counter
Players who want a higher number in a screenshot of the F3 screen can use the mod for that purpose.
Who it’s for: Players on Minecraft 1.20.4 with Forge who want the F3 framerate counter to show a higher value. It is not intended for anyone seeking a real change in game speed.
