lazyboost-render
LazyBoost is a client-side Fabric and Quilt optimization mod that raises rendering performance and exposes many visual options through its settings.
What it does
The mod targets client rendering, so frame rate can improve during play. Its configurable visual options cover entity rendering, weather, sound, HUD elements, brightness and hand toggling, and an automatic frame-rate reduction can apply when the window is not in focus. Only the client needs it; a server does not run it, and a server-side install would do nothing.
Installation needs Cloth Config API, Mod Menu and either Quilted Fabric API (QFAPI) or Quilt Standard Libraries (QSL), in addition to the Fabric Loader or Quilt loader. Mod Menu adds an in-game screen for the settings, which is optional but convenient. Builds exist for 1.20 – 1.21.11, with 1.0.5-beta.1-1.21.11 as the latest Fabric file for 1.21.11 and 1.0.0+1.20.1 as the latest Quilt file for 1.20.1. The code is open source under the Apache License 2.0.
Key features
Entity rendering options
Simple entity rendering settings let players tune how entities are drawn, which can reduce rendering cost in busy scenes.
Automatic frame-rate reduction
The mod can lower the frame rate automatically while the game window is not focused, to save resources in the background.
Brightness toggle
Gamma brightness can be switched on and off quickly from the settings, without opening the full options menu.
Weather, sound and HUD settings
Weather, audio and HUD elements have their own configurable options, so visual and sound detail can be traded against speed.

Use cases
Who it’s for: Players who run the client on Fabric or Quilt and want to adjust rendering cost and visual detail. Server owners do not need to install it, since the mod is client-side only.
How it compares
Advanced HUD is a client-side Fabric and Quilt mod, open source under the GNU Lesser General Public License v3.0 only, with files for 1.20 – 1.21.5, so it covers an older version range than LazyBoost. HUD - FPS Veltium is also client-side, runs on Fabric and Quilt, is open source under the MIT License and covers 1.21 – 26.3. Entity Render Disabler is client-side on Fabric and NeoForge, not open source, under All rights reserved, and targets 1.20.4 – 1.21.11, so it focuses only on entity rendering.
