worked with NVDIA online chat support, they provided the following. Tried it and it did not help much.. i get best frame for a while (longer) with x-plane rendering Preset to low...
i share below the detail of the conversation if anyone can use.. and have more luck than me. Note: to date- silence from x-plane support. No one has even responded to my queries.

Denis Meuret: for some unknown reason, X-Plane 10 drop the fps from 30 to 5 after playing it for a bit... most time drop frame occurs when i navigate out of game on one screen and gor to 2nd screen...
Denis Meuret: what about the program setting tab? Denis Meuret: 1.Select a program to customize?
Denis Meuret: anything there i can adjust for better performance?
