In the initial areas while you're still in a wheelchair my FPS was similar to the 1070 Ti/1080 in maxed settings at 1440p, the massive drops began in later areas. Since the game doesn't have a benchmark tool we have no clue what area/scene they are using.
With Watch Dogs 2, I think I may not have played that since swapping to SLI 980 Ti from base 980s in SLI so I may be remembering the 980 performance
