Very Poor Preformance In Game

Nvidia Gforce GTX 1080TI Gigabyte
Intel i7-9700KF

the game feels extremely choppy and at High, Medium and Low settings. No matter if i reset game and try each setting it runs very poorly.
Choppy feeling, FPS hits 135 in menu yet in game goes down to 120 to 110 but does not feel like it, it FEELS like 50 fps.

If i limit FPS IN GAME, i lose 10 Frames no matter what.
If i can sit at 120 frames why do i lose 10 frames for turning on Vsync?

If i turn Vsync on in Control Panel i lose over 15 frames.

Game runs and feels very clunky on my system. Feels like a battlefield game in terms of how it runs on my PC, which isnt good at all.
This is extremely disappointing and extremely worrisome. I cannot play this flight, again, just like the last one because of how poor it runs. Feels like -Yoink-, plays like -Yoink-.
