Somewhat guiltily (I'm a refugee from X-Plane 11), I purchased the top MS Flight Simulator 2020 package, and because of the hype - I was expecting wonders which should not be missed!
However, over several days my fairly beefy Windows 10 system froze numerous times with screens of various colours whilst I tried to download the new simulator, then when trying to install it, and then when trying to run it. However, I seemed to be progressing slowly, and my system was within spec, and I had of course done all the recommended OS and driver updating, so ultimately there was no reason for it not to work. So I persevered.
Then maybe all those hardware resets were just too much for the system, because the motherboard just gave up the ghost. Maybe too much strain, and no way for the poor motherboard to complain to me what I was putting it through, other than by putting an end to its own misery.
Luckily the local computer store had in stock a ASRock x570 Steel Legend, a Ryzen 5 2600 processor and 32GB of memory to suit. Not the top end, and reasonable at AUD $805 (that would be USD $578 to you guys).
I was confident now that I could now run Flight Simulator from its own dedicated SSD (drive E:) without problems. But no! Blank screens of various colours at different times. Have not managed a flight yet. Mere crash to desktop would be nice compared with the frozen screen! You're lucky guys!
PS. The furthest I got with the application was when I opened it through GeForce Experience. This is "a companion application to your GeForce GTX graphics card keeping it up to date and optimising your game settings etc. etc.". Strangely, it lists the games on the machine and allows you to run them through the app. I got into the various controls, cameras etc. but the controls didn't actually work this time (they did work once previously).
