Guys, I'm having a serious performance issues with the JS41 in all scenery and whether situations. Comparing to MD-11 for example, the MD-11 is so less performance killer than the JS41. And the MD-11 seems to be a mutch more complex aircraft.With the JS41 I usually get 8-15 FPS, with constants glitches and stutters.I know, it's a whole new approach to simulation, and also isn't that easy to simulate a turboprop aircraft, and so on. But my machine is not that bad, and I barely can fly with this baby.Finally I have to say, fly this baby it's a new experience to the Flight Simulator X, the sensation of "being there" it is so amazing. Thanks for that. My specs: Core I7 920 Clocked to 3.3GHZ6GB RAMZotac GTX285 1GB Ram.Windows 7Paulo Bernardo S. SilvaBrazil
