MSFS runs great imo. You have to turn down settings to match the performance you want. Personally I think with a mix of high/med settings (a few things on ultra) it still looks beautiful and runs really smooth on my RTX2060.
Compare that to FSX which was a mission of tweaking cfg files and nvidia profiles just to maintain 30fps.
On NVME the game still loads in 5min despite having all the world updates and a lot of 3rd party planes and mods.
