Loading the game and selecting a flight to work with, the scenery movement skips every 2 1/2 seconds. This skipping occurs with every aircraft, even with all the settings turned all the way down. This will occur regardless of the view being displayed as long as there is movement it will skip (almost exactly) every 2 1/2 seconds. What can I do to stop this? This started only a few days ago and I don't know what I might have done, changed or loaded to create this.
