Performance (at least at planetary stations like Chamberlain's Rest) was bad pre-patch, is actually worse now for me on a 1060 GB, Ryzen 5 2600X. There's a sort of rubberband performance thing, running around, is smooth, then lags, then smooth, depending on where you are. Rivatuner framerate monitor shows the frames jumping around with it, not a connection issue. And all my inputs are laggy now too, takes a couple of seconds for me to get to the pause menu.1080p, everything set to Medium or High, as it was pre-patch.
Also tried deleting the Graphics folder for a forced graphics reset, no change.
Edit 1: Getting just 15fps in places now, compared to around 25. Something's gone backwards. this is so deflating.
Edit 2: Dropping my settings to Low doesn't seem to be making any difference either.
Edit 3: Performance (for me, anyway) for planets has actually improved, now able to go back up to Ultra for every setting regarding planetary tech and stay between 45fps on the ground to 60fps in orbit. That's a definite improvement.
The one thing I've noticed is that my framerate tanks when I'm inside a "social" area (i.e. Chamberlain's Rest) and there's GLASS. For example, at Chamberlain's Rest, if you go inside the Pioneer Supplies store and look back out through the window towards the bar (where there are multiple layers of glass there too), the framerate plummets. Step aside and look through the doorway, it goes up a bit but not by much. Anywhere where there's glass or perhaps reflections too, that's a problem. I personally don't know which setting controls reflections but I've tried turning everything down or off to no avail.
