I am former FSX user for many years and have been very pleased with the x-plane 10.51 I had no problems with the install with dvd installer. My frame rates are running from 20 to 50 fps with some rates going to 17 fps in clouds and high detail ground and into the 70s in the air. The KC10 seems to be responding well even at 17 fps.
