This what I did.
1.I turned off (moved traffic sliders to 0) didn't see much change.
2.I moved the traffic sliders back to 18-airline, and 11 general.
The aircraft was sitting on the runway and I got side tracked; went back to look and the frame rates were 19.5-20FPS. My new system is extremely robust. I guess the problem is solved
Just a word of note: I wasn't complaining, just wanted to understand. Your sceneries are the best out there! I look forward to updates and future sceneries that I can add.
Thanks for your attention and help.
