I can share your pain.
I run MSFS on a lenovo ideapad 330 laptop (i7-8750, 20gb of ram and a GeForce GTX1050 4gb). Definately choked by the graphics card. Am getting around 22FPS consistently but I also drop after a longer flight. I find 22FPS ok.
The last flight I had was LA to Boeing Field in the Bonanza as part of my Round World flight; on approach was down to 9FPS - I can definately say that 9fps is unflyable! Got the plane down and there were tears on the runway which I think were related to my low frames, hit one, crashed! Gutted!
These are my settings if it helps.
This is also a good post explaining how to optimise settings…
