As promised, this is a follow-up to my previous testing. I landed on Sarake and the framerate plummeted to 25fps! External view dropped it even further to 17fps!
After doing some vertical bobbing up and down, it seems to slow down under 50m altitude (getting worse as you get lower). Framerate evens out above 50m (roughly).
Oddly, it was 19fps when hovering 10m above the ground - lower than when landed.
Edit: the loss of fps does not occur on Aresthia. It drops to low 40s for me when landed, but that's it. So could it be linked to the temporary vegetation? Or is there something about the surface on Sarake/Cinder that is different and causes fps to slow down? @INovaeFlavien
Edit 2: I LOVE THE CORVETTE'S NEW WEAPON EFFECTS! Looking forward to when we properly get to work on weapons!
