Usage
All commands are client-side and start with /multicoremagic.
| Command | Effect |
|---|---|
/multicoremagic status |
Shows enabled state, thread count, active/queued tasks |
/multicoremagic threads <n> |
Resizes the dedicated pool live — no restart needed |
/multicoremagic on |
Enables the dedicated chunk-builder pool |
/multicoremagic off |
Disables it, falling back to vanilla's shared pool |
on / off take effect on the next world join or resource reload (F3+A).
threads applies immediately, no reload needed, since it just resizes the existing pool.
Multicore Magic: enabled | threads=7 active=2 queued=0
- enabled — whether the dedicated pool is in use (vs. vanilla's shared pool)
- threads — configured pool size
- active — threads currently busy building a chunk mesh right now
- queued — chunk build tasks waiting for a free thread
If queued stays consistently high while flying through new terrain, raising threads may help.
If you see general stutter instead, see Troubleshooting before raising it further.
If Mod Menu and Cloth Config are installed, open Mods → Multicore Magic → Configure for the same two settings as the commands, with tooltips:
- Enabled — toggle the dedicated pool
- Chunk builder threads — slider from 1 up to (CPU cores × 2)
The default thread count matches vanilla's own formula for its shared pool: CPU cores − 1. This
is a safe starting point — the mod's whole point is giving that count of threads exclusively to
chunk building instead of sharing them with worldgen.
