Lighter. Faster. Smoother.
Catalyst
Next-generation Performance mod for Fabric that actually does what it says
Compatible with
Why We Are Nº1
Fabric Performance Mod?
Fast, lightweight, and plays nice with your other mods. Thats kinda the whole pitch.
Massive FPS Boost
I rewrote the render pipeline (definitely lol). Not exaggerating.
No More Stutters
Chunk loading used to freeze your game for half a second. We fixed that. Explore all you want.
Uses Less RAM
Your modpack eats 8GB? Try 4-5 with Catalyst. Same gameplay, way less memory overhead.
Drop-in Install
Install from Modrinth or get the build .jar file from our Gitlab.
Fully Open Source
MIT licensed, code on GitLab. Read it, fork it, contribute. I review PRs pretty fast too.
Works With Everything
Sodium, Lithium, Iris, whatever else you run. I test against the popular stuff so you dont have to.
Smart Culling
If you cant see it, we dont render it. Sounds obvious but vanilla Minecraft doesnt do this well.
Actively Updated
1.21.10 and 1.21.11 support right now. When Mojang drops a new version I usually patch within days. (will be for 26.1 soon)
How It Actually
Makes Your Game Faster
Wont Break Your Mods
We dont do destructive patches. Your Sodium, your Iris, your 200-mod kitchen sink pack; all safe. If something breaks, thats a bug and we fix it.
The Definitive Fabric
Performance Mod
Works on Fabric 1.21.10 and 1.21.11. Literally just put the jar in your mods folder and launch. We didnt add a config screen because you dont need one.
