[Flightgear-devel] Multi core discussion

[<fie...@zo...>]

Hi

I do not know if this has been discussed in this group before... (I am 
guessing it is...)

Many modern computers are running multicore CPU's. I have noticed that 
FGFS only uses one thread in one core. And FGFS appears to be processor 
bound on my Core-I7, because the one core thread is 100% busy while my 
FPS are dropping in areas with a lot of scenery details (like Paris, for 
instance) and lots of rendering goodies switched on.

I do understand that in the main loop of FGFS many subsystems are 
related. But would it be possible to identify subsystems that can be 
grouped to run on other cores, when available? I am thinking about 
weather and clouds, drawing the dials on the dashboard and things like that.

It would be neat if more of the computing power that is available could 
be used.
