Update 9 has improved my frame rates across the board byt a good margin. I have not, so far, seen any game reported frame rates in red or yellow in the 3 or so hours that I played last night/this morning (planetary, station, port, settlement, concourse, hanger). In fact, I've been able to move the rendering distance slider from about 60%, where I had set it previously, all the way back to 100%.
I'm pretty sure planets are rendered now, as I've seen several in the last 6 months since the OP. Though whether they are rendered correctly or not is still up for debate, I'm sure.
This update has been much much better than any other in terms of performance.
There are a few glitches I've experienced with planetary surface features (rocks, plants, etc...) disappearing/reappearing en masse as I fly over/near them.
