I have the 5800x3d and just got my 4080. I thought the performance increase was terrible over my 3080 12gb oc. The flight sim 2020 fps counter didn’t go up significantly over the 3080. However when in VR I used the nvidia fps counter and that’s when I noticed the flight sim 2020 wasn’t seeing my proper fps with dlss enabled. With all ultra settings and dlss quality I get 75 fps average in NYC cessna discovery flight. With dlss dlaa setting enabled I get approximately 45 to 50. Depending on altitude. In built sim doesn’t seem to count fps correctly when using dlss in vr. Also I am using the reverb g2.
