I have a Radeon RX 68000 with 16g VRAM. running on a Gigabyte MOBO with pretty much the best AM-4 socket processor I could find.
The software-derived defaults are 99% “High” (as opposed to “Ultra”)
I have been working on getting the simulator to install and run without trashing my MSFS-2020 installation, (or crashing ), so I have had zero flight time yet.  (And with the granddaughters here for the holidays, there might not be much of an opportunity for me to touch it. 
)
However, I will be glad to report results when I can.
P.S.
I have started my own thread where I am documenting my own adventures with FS-2024.
You can follow my adventures there as that’s where I post progress first.
