I am not having performance problems. All is well, but I noticed that only one core thread is used while my Linux reports 8 available (4 cores times 2 threads). > FG itself isn't CPU limited, we barely use any processing power :) As > such, parallelizing FG subsystems, while a good thing in theory and > certainly for the future, wouldn't help much in your case. > What you are seeing must be graphics related - you even say so > yourself.

I can dump the Scene Graph (442MB, by the way), and I can look at the frame rate... I have searched the wiki, but cannot find an option for on-screen OSG stats. Which on screen OSG stats option do you mean? > Also note that if you don't run with an FPS limit (either in FG or the > sync to vblank option in your graphics driver) we will use all > available power to push out frames as fast as possible. > Yep. I know. When I start, I get 160 fps or something like that with 100% cpu. When I switch on rendering options it remains more or less the same. Depending on the weather, I guess. Now I reposition to LFPO, which has a lot of detailed scenery, and my frame rate drops to 25-33. Still, no problems to fly happily. I agree it remains to be seen if anything improves by a multithreaded approach. I probably should not have started this topic, esspecially since it has been a subject of debate at Linux TAG.
