AyEyed…
I’m going to drag as much life out of my RX590 as I can. 
I refuse to spend $2000 on a video card for this game. $2000 gets you an FAA approved IFR flight simulator with money left on the table.
I will say MSFS 2020 runs just fine in 2D mode. It’s perfectly smooth and a delight to use. VR mode with an RX590… not so much.
