Hi Martin, That did the trick for the display frame rate, thanks.

Hi Csaba, I've been playing a bit with passing the model-hz as command-line option and the following are my observations: - Setting model-hz through the command line options to e.g. 600, everything works fine. Setting it back to 120 during flight, makes the plane 5 times as sluggish. - Leaving model-hz at its default (120) at startup, everything works fine. Then, setting it in flight to 600 makes the plane respond/fly 5 times as fast. So it seems that only changing /sim/model-hz in-flight results in wrong behaviour/outside visuals (with fg/osg). Can anyone confirm this?
