New York City X is a real flight sim killer.
Until now I couldn't fly it with any of the settings above the lowest of settings.
I had the memory - 32GB. I had the CPU & GPU, in fact my video card has 8GB of DDR5.
But even at the lowest of settings it would crash after a relatively short time. On even moderate settings it would crash FSX/P3d V3 in less than two minutes.
That's no longer a problem.
This isn't an install, I just pulled the files over to P3d V4. When they come out with a real V4 install It may, or may not, look better.
