Hello again, normally I work on a rather slow machine (one that really screams when I load up the bandit model with its many polygons). When I installed Gazebo on my desktop at home, that is not quite high end, but almost, I noticed something peculiar. When I leave the simulator alone, it will run at 30 FPS and the speed of the simulation (measured with a stop watch and the "simulation time" in the status bar) seems about right. But when I move the mouse over the Ogre window (the 3D window to the simulated world), the framerate jumps as high as 300 FPS, accompanied by a five to tenfold increase in the simulation speed. I'd also like to remark that it seemed like the time step wasn't constant anymore, because my robot started to twitch and jump around. I didn't test this thoroughly, but I recall that it (the robot) only behaved weird when I stopped moving the mouse and the framerate started dropping, not when I built up the framerate or kept it at a high level.
I suspect the window has to be redrawn quite often when some maniacs frantically moves his mouse cursor over the image, so I can understand the jump in the FPS. But why the increase in simulation speed? I was pleasantly surprised when I discovered that the timestepper just "takes his time" when updating the world, regardless how slow the machine or small the timestep is. I wouldn't have thought that it would misbehave like this on fast machines.
