I should have said that better-my bad. I should have qualified with limited testing and while sitting and flying around on planet surfaces. I am sure there would be settlement areas an maybe some planets where there would be many exceptions. I was more speaking to the Op's upgrade path and an idea of what a gpu might afford than any definitive testing. It was not my intention to mislead.
What little testing I did was described here

I did not test all surfaces and there were no settlements. My settings in the test were pretty much what Tor posted here except for the HMD setting and if I recall I may have had shadows at high rather than ultra.
I am surprised that you say you "never" get 90 on planet surfaces at 1.5 with a 1080ti. Many factors beyond settings seem to be able to affect fps in Ed, such as where you are and how you play, number of AI, number of player, if you are even on-line, cpu class and clock, gpu class and clock, speed of ram and who knows what else, but one would think you should be able to get 90 at 1.5 out of the card somewhere on a planet.
