It will run like ass on Ultra on a 1070 if you are playing at 2K or 4K resolution. Runs at 60+ FPS on Custom (Medium-High) settings with a 1070 and a 10th gen i7 at 2K resolution for me, dunno how anyone is running Ultra even at 1080p. I tried Ultra at release and it was below 30FPS, but the patches have helped improve game performance significantly.
