Catalyst

Fabric performance mod for Minecraft. Speeds up rendering, resource loading, and block entities. Works with Sodium.

Features (may change over time)

Rendering

- **Modern GL Context**: forces Minecraft to use OpenGL 4.6 and applies core profile instead of the default outdated OpenGL 3.2 - **Async Meshing**: chunk meshes get built off thread, prioritized by distance to camera - **Mesh Cache**: only rebuilds chunk meshes when something actually changed - **Render Batch**: groups draw calls with matching render state together - **Render Cull**: skips sign text and beacon beams at distance, turns off beacon beam rotation

Resources

- **Async Reload**: resource packs reload in the background, no freeze

General

- **Enable Catalyst**: turn the whole mod on or off - **Debug Mode**: spits debug logs into the console Everything is toggleable from the config screen. Get to it through Mod Menu, Sodium's config, or the Catalyst button on the title screen.
