Another way to maximize the Vram usage and consequently the visual quality is to choose of course the Ultra mode and beyond that to push the scale factor from 100 to 150. This simulates a resilution pushed from 1440x…to 2160x…, i.e the full 4K res. Doing this, the frame rate is still above 30 fps, no stuttering but the GC is loaded at 100%. In this case the graphics are fantastic, they look like the MSFS official trailers, especially for the water. The attached screeshot has been taken during a take off from LFPO, heading to Paris at low altitude (500), real time and real weather.
No other GC is can do that ! Yes the RTX 3090 is already useful on MSFS and the future promises that it will be more and more true (DLSS, DX12,…)
