FGFS doesn't use threading much at that time. Only for the scenery loader and

divide the viewport into small areas that could be rendered in parallel. I
don't know if its doable, but for now, you will only see an improvement running
multiple programs in parallel. As you already see, Atlas or Terrasync can run on
their own core and not disturb FG.


In FlightGear we intentionally minimize the use of threading to places where there is a huge need.

Adding a thread significantly increases the complexity of the code and can hide a large variety of execution order and timing problems which can be incredibly difficult to debug and fix.

If we are ever add additional threads, it will be only because we are forced to by clear and overwhelming performance considerations (and not for design or preference reasons.)
