I have gotten close to airport and Jet freezes and then program exits. I have 4 gigs on card, Rysden and one Tb at 3.4 mgz. The taskmaster performance chart in Microsoft show 32 percent memory use and high power usage. Simming for many years, and this is improvement over FSX but stability is questionable. Please help.
