Installed my new 5800X3D yesterday evening and the system is running very well with -30 on all cores in PBO/curve optimizer. There's a significant uplift in MSFS2020 : with my older 3900X I was getting approx 40 fps at 1440p taking off from my local airport, compared to 80 fps with the 5800X3D. Even tried a takeoff from JFK in New York and was getting low 50's ; on my previous CPU that would give frame rates between 20-30 fps. For context this is using a 3440x1400 ultra wide monitor with a RTX 3090 FE.
