A new release of the minecraft mod c2me enables a GPU to compute chunks, so is much faster at rendering the world.
I’m trying to run it on my self-hosted minecraft server, managed by Crafty Controller running as a docker app, under Dockge, in TrueNAS 25.10.0.
Crafty has been running fine and runs several other servers - all good. And my GPU (a GeForce 1660) is detected and running fine in another Dockge stack, Jellyfin - transcoding on order, confirmed by nvidia-smi in the TrueNAS shell.
However, when trying to start my server with the c2me mod, I get:
[Server thread/WARN]: No OpenCL devices found [Server thread/ERROR]: Failed to initialize OpenCL context java.lang.IllegalStateException: No OpenCL devices found
And running ‘clinfo’ in the Dockge console or Crafty console/shell only shows my CPU as an opencl platform.
Thoughts, o wise ones?
