My use of graphic settings has always been based on my system.As I upgraded my comp I also am able to run higher settings. The settings for me are same with all FSDT airports. The only settings that I MIGHT change are ,scenery comp and autogen. Which are Dense. Any way if you find good settings for most of your sim they should be ok for JFK. You must remember there is always hit in fps so lower that to find best preformance and scenery.Just try and try.
