Ubuntu 18.10, Intel(R) Core(TM) i7-7500U CPU @ 2.70GHz (4 cores):
@nic, thanks for your feedback.
So on Ubuntu stock, FC acts as a single core @100% instead of using the multi-cores...
I have the same result on Mint..
This is disappointing because the computer becomes quite unresponsive and the cpu get triggered to a high temperature level...

But i found this on the opencascade site "https://dev.opencascade.org/doc/overvie
USE_TBB --> Indicates whether TBB 3rd party is used or not. TBB stands for Threading Building Blocks, the technology of Intel Corp, which comes with different mechanisms and patterns for injecting parallelism into your application. OCCT remains parallel even without TBB product
That is interesting... so probably the multicores multithreading present on Win is related to loading and parsing the STEP file, more than the OCC process.

Have you tried @Marksters OOMP_NUM_THREADS=<num> ? I don't know if the AppImage will respect it, but the daily PPA should. This is used in FEM for calculix, in a subprocess call.
Yes, I have tried the @Marksters option, without any result.
Is there anyone that could also test the loading of the STEP file on OSX to check if there multicores are triggered?
