I'll give you Watchdogs, but I ran AC3 at an almost perfect 60 FPS back when it first launched. If I recall I had to lower the draw distance, but that was the only issue I remember having.
The whole point of me saying that was to illustrate that unless you can run the released version at 1080p max graphical settings with 120+ fps, there's no way in hell will people would be able to run the game at the same settings as E3 "gameplay" videos.
The amount of graphical fidelity for the resources you give them is poor and bruteforcing seems to have has steep diminishing returns in those games.
