For me most of the performance issues with MSFS24 are now being VRAM limited. When they went to MSFS 2024 they rewrote for DX12 and while doing that upgraded a few things to look nicer. The texture management still seems to need some work.
This means that my 9800x3D/3080Ti 12GB sort of runs out of VRAM and pages when used in VR or 4K desktop. I'm in the position where the same visuals (scenery/aircraft etc) for MSFS2020 (using DX11) when compared to the newer MSFS2024 is just generally worse and a lower framerate. In VR a bad framerate makes things unplayable. For desktop use you have DLSS which helps a lot, but in VR that blurry movement really impacts clarity.
