Don't know what the framerates are sorry but it's very smooth. I have a 9700k CPU at 5ghz and my 3090 is a gigabyte gaming oc. Terrain resolution is ultra, and all other settings combination of high and medium. 150 for terrain data, 120 for buildings. So long as you don't fly in mega cities it's smooth as a babies bum. Oh render scale at 80, which on G2 is just about perfect. Airliners and third party aircraft, Mooney in my case, take a frame rate hit but not too bad.
Thx for sharing your settings i have pretty much same setup as you but runing the 3080 OC model and 32GB of ram
