GpuShift

GpuShift singles out the rendering jobs that tend to cost the most in certain scenes, mainly many distant living entities and many cosmetic particles. When the render budget is exceeded it skips some distant non-player living entity rendering and caps newly spawned cosmetic particles against a configurable particle budget. Players, named and glowing entities, close entities and weather stay protected, and the mod lists known compatibility cases.

The mod does not move work to the GPU or raise frame rates on its own. Its effect is most likely where the processor is the limit during client rendering and many particles and distant living entities are on screen. In lightweight scenes, or in modpacks where another optimization mod already handles that work, the change is small. An optional overlay shows FPS and frame time, and the skipped entity and particle counters show whether GpuShift is active in the current scene. F8 toggles the overlay, F9 opens the settings, and the default Balanced preset is set conservatively.

GpuShift is client and server, so the server and every player need it. It is published for Fabric, Forge and NeoForge in two game versions, 1.20.1 and 1.21.1, under All rights reserved, and it is not open source. Installation requires no hard dependencies, and a one-time quick setup screen appears on the first world or server join.
