I've seen a subjective improvement in frame rate over the last few days. In the same situation as you outline above I get 56 fps. This is half what I see at a simple airport like EGMH, and third of what I see over ocean. The tall pole in the tent is the KSFO terminal: if this is in view the frame drops to around 44. Enabling every shader, Random Veg, Obj and Bldgs etc. drops the frame rate to 30 fps. Being selective about which shaders are enabled doesn't change that significantly. On the other hand, disabling Random Veg , Random Obj or Random Bldgs does increase the frame rate significantly - about 5 fps each. Not scientific I know. The frame rate should continue to be displayed after a restart if you enable it then exit FG using ESC - not just shutting the window. Your selection should be auto-saved. It works here, and if it does not that's a bug.
