Game is very CPU limited.
I’d def. go AM5 for future, and consider 9x3d
difference between 5x3d and 7x3d is noticeable in MSFS (not all games) as I have both.
I’m waiting for 9x3d to become available as people are showing 15-30% increase in fps.
I’m currently CPU limited with a 7900x3D/4090 setup. If you are CPU limited, then you will see the higher end of fps increase.
