Of course with very limited testing:Sorry if I sound critical guys and gals but I am working (ish) while you are playing: please could you say how much better/worse it is compared to update 7 using same graphics settings??
2070S, 32GB, 9400f
4k, FSR Ultra Quality
All planetary surface settings to Ultra(+), other settings medium/high
Concourse seems a little bit better, around 10%. Settlements still very erratic, between 30-50, hard to say if it is improved or not with certainty. While the massive drops to 1FPS seem to be gone (though I havent tried CZs yet), my very early conclusion is: if this is what Arf's 'core code team' has been doing for six months, and if this is Sally's 'significant performance improvements', then what you see is very much what you're going to get both now and in the forseeable future.
I hope I am missing something, but at this point I really don't see any real reasons why anyone should believe 1) FD is able to properly fix this, or 2) whatever the community team says in general. I honestly lost count how often Honest Arf has been kicking the can down the road to the next update, and at this point mabe they should just give up and buy a football instead.
Anyway, its Friday so I earned a little brandy now.
