Up to 2x fps on Retina Macs and other high-DPI screens: Minecraft renders at standard resolution instead of four times the pixels. Can also lower just the world's render resolution and keep the HUD sharp. Client-side.

Description

PixelBudget

More fps on Retina and other high-DPI screens.

Fabric · NeoForge · Client-only · 26.2 – 26.3

On a high-DPI screen Minecraft draws four pixels for every one you'd notice. PixelBudget has it draw at standard resolution instead.

Frames per second with and without PixelBudget

How much faster

Tested on a MacBook Pro (M4 Max), 3200 × 2000 window:

Without With
26.3, Fancy ~160 fps ~400 fps
26.3, Fabulous ~115 fps ~160 fps
26.2, Fancy ~175 fps ~340 fps

Your numbers will differ. On a normal screen it does nothing.

The same view at full and at standard resolution

Does it look worse?

Barely. The hotbar, items and font are pixel art, so they stay crisp:

The hotbar at full and at standard resolution, enlarged

Want full sharpness back? /pixelbudget window full, or "Whole game" in the settings. Takes effect after a restart.

Only the world smaller

You can also draw just the world at a lower (or higher) resolution and keep the window at full resolution: a percentage, a fixed size or a pixel count, sharp or smooth. Useful with shader packs or a weak GPU.

The world at 100%, at 50% smooth and at 25% sharp

Already using retiNO or Sodium Extra?

They do the same for the whole window, and do it well. Keep using them if you like. PixelBudget works alongside retiNO, Sodium and Sodium Extra.

Why I made it

I run automated tests for my mods, several game windows at once, while I keep working. Those windows made my machine slow. Now they run with PixelBudget at a quarter of the pixels.
