<snip> >After I had fixed the worst stuttering by always running FlightGear with "vertical sync on" (see former discussions on >this list) there was still this stuttering left which you all describe as "framerate hesitations". <snip>
The thing about running with Vsync on is that you will always get 60fps (say) unless each frame takes longer then 1/60s (16.6ms) to prepare, which will cause a dropped frame as a minimum, and running at 30fps or 20fps if the interruption is longer. Even if the frame update time is 17ms (58.8fps) you will only see 30fps on screen. Even one or two frames at half your regular frame rate will look like a stutter. If you are running with a high refresh rate (100Hz, 85Hz) you may want to reduce the refresh rate to 75Hz or even 60Hz to see if it reduces the stuttering.
