betterperf
by Flamingoo
BetterPerf is a Fabric optimization mod for 1.20.1 that targets frame rate by culling entities and thinning out AI work.
What it does
Entity Culling hides entities the player cannot see, so the renderer skips them. The author describes this as a way to cut rendering load noticeably in scenes with many mobs or other entities. AI Optimization reduces how much processing mobs receive in large mob farms and near spawners, which the author links to fewer TPS drops and less lag in those places.
BetterPerf is set up to work without a configuration file: after installing it, the default settings are applied. The author describes it as built to raise game performance without complex setup. The mod is published for Fabric only, for 1.20.1, and is released under the MIT License, so the source code is public and open source.
Key features
Entity culling
Entities the player cannot see are hidden on their own, so the client does less drawing each frame.
AI processing reduction
Mob AI is thinned out in large farms and spawner areas, which the author links to fewer TPS drops in those areas.
Works with default settings
No setup is needed after installation, so the defaults apply without editing any options.

Use cases
Large mob farms
Players running large mob farms can use the AI reduction to limit processing load where many mobs are active at once.
Crowded scenes
Areas with many visible entities gain from entity culling, since hidden entities are skipped during rendering.
Who it’s for: Players on Fabric 1.20.1 who run mob farms or spawner-heavy builds and want lower frame rate and tick costs without tuning a configuration.
How it compares
Particle Culling is a client-side only Fabric mod for 1.21 – 26.3 that is open source under the MIT License, so it targets a different version range and a different kind of culling. Iridium is a Fabric mod for 1.21.1 that can run on the client, the server or both, and its license is a custom one, so it is not open source. Too Many Players is a client-side only Fabric mod for 1.18.2 – 1.21.1 that is open source under the MIT License.
