Turn Render Scaling down to about 60, turn everything to Low except Terrain Textures, turn all other traffic like Marine and Vehicle to 10, drop offline AI on airliners and GA to below 10. Turn all static objects at airports to lowest setting.
I get an average of 45 fps even with different Cloud presets from Sofly. And I have the same hardware as you except my CPU is a Ryzen 3 previous generation, so you should be getting better fps than I.
My Vsync is on and locked to 60. My monitor is an older flat panel at 60Hz so it’s fine. And locking the Vsync prevents a runaway GPU cooking itself on the Main Menu at 3 digit fps.
