I'm a gamer since the very beginning on the C64. I am used to have stutters in my games for 30 years. So why should I worry about stutters? It is a game and not reality. Sure, it is better to have more fps, but I will not die for a good frame rate.The only nasty thing with these stutters is that when you start with a new software like the NGX, with each stutter you expect that FSX will crash. So currently I have a lot of light heart attacks every day. Martin
