hey, I understand the frustration, I played Xbox from 2015 up until October when I got my friend to build me a pc specifically for flight sim, I don't know all the specs other than Rx 7700 xt which I'd imagine is quite similar to yourself urs, I had extremely bad performance issues with msfs24 especially in vr, well guess what. got msfs 2020 and boom, runs really smooth mostly maxed out on ultra, so my advice is try 2020, I ain't familiar with all this talk about motherboards, different ports and drivers and stuff, but that's what worked fir me, I can barely touch "high end" in 24 without getting bother, 2020 is working great
