Boosters
Throttles distant mob AI, culls off-screen entities, slows down far-away block entity ticking (except the ones you'd actually notice, like hoppers and pistons), and cuts particle count — deferring to Sodium/Lithium/EntityCulling instead of fighting them.
Quick answer
Which Boosters release matches Fabric?
boosters-1.3.4.1+26.3-fabric.jar targets 26.3 with Fabric. The project page does not say whether this file belongs on the client, dedicated server, or both. All 3 required mods have matching files.
Where it goes
Is Boosters required on the client, server, or both?
The project page does not say whether this file belongs on the client, dedicated server, or both.
The source does not explicitly classify this release as client-only or server-only.
What else does boosters-1.3.4.1+26.3-fabric.jar need?
boosters-1.3.4.1+26.3-fabric.jar on Fabric. Every mod below is checked against that same setup.
Install Fabric API, Cloth Config API (Fabric/Forge/NeoForge), Cloth Config API first. We found matching files for this game-version and loader setup. 1 comes through another mod in the chain.
1 extra mod was pulled in by another dependency. Indented rows show who needs each one. We only count dependency files that match this setup. A file for another loader does not fill the gap.

About this project
What does Boosters add?
Boosters
A performance mod. Built it because my singleplayer world started chugging once I had a proper base going and more mobs than I'd like to admit wandering around. Most performance mods try to do everything.

This one doesn't
it picks a few specific problems (mob AI, entity rendering, block entity ticking, particles) and leaves the rest to mods that already handle it better.
Features Mob AI throttling
mobs far from any player update their sensing, pathfinding and target selection less often, scaled by distance. Nothing changes for mobs near you. Entity culling - entities past a configurable distance simply don't get rendered. Same for nametags, with their own separate (tighter) cutoff.
Block entity throttling
furnaces, signs, and similar tick slower the farther they are from a player.
Hoppers, pistons, beacons, conduits, brewing stands and sculk are excluded by default, since those are the ones where throttling is actually noticeable (stuck items, stuttering pistons). The exclusion list is editable in the settings. Particle reduction - a density multiplier plus a hard distance cutoff for particle spawning.
Block entity renderers
shorter render distance specifically for chest lids, sign text, skulls and banners, separate from the block model itself. Plays well with others If you have EntityCulling installed, Boosters detects it and turns off its own entity culling automatically - no reason to duplicate worse occlusion logic when a dedicated mod already does it properly. Sodium, Lithium, C2ME, Starlight, FerriteCore, Krypton and Noisium are all detected too; they operate on different layers of the engine so there's nothing to disable there, they just coexist fine.
Configuration Full settings screen via Cloth Config, accessible from Mod Menu if installed, or through a keybind (; by default) if not.
Press F3 to see a live line of what the mod is actually doing per second - AI throttled, entities culled, particles dropped - instead of just a version number confirming it's loaded. ## One honest disclaimer This isn't a rendering engine rewrite, so don't expect Sodium-tier numbers from it alone. It's throttling and culling logic that reduces real work the game does - the gain depends entirely on your scene.
Big base, lots of mobs, storage rooms full of chests?
You'll feel it.
Empty superflat world?
