Unity has a wide disparity in model quality, however. Sure, Elise (dat hair) and Arno look gorgeous, main characters look good, but side characters and random NPCs just look OK even up close. It also uses different graphics in cutscenes (the hair is especially lower quality in gameplay). Inquisition has every model using the same chargen, I think, so it doesn't have that. Maybe the game will prove me wrong, however, DA2 certainly did.
Unity also has a ridiculous optimization problem. With the latest drivers, my AMD Phenom six cores @ 2.9 GHz and R7 260 graphic cards (not top of the line hardware, but mid-range or above) barely manage an acceptable (for me, 40+) framerate on medium, no SSAO and no AA, and in some cutscnes it tanks to 20 for no apparent reason. Meanwhile, I can max Black Flag (which apart from character models looks better than Unity at those settings) except for anti-aliasing, and the comparable-looking Shadow of Mordor I can go on High or Very High on most setting with a very smooth framerate that never goes below 50. Something is fishy here.
As for Inquisition, that article actually praises the graphics overall, and says it's also CPU intensive (it's a Frostbite game before driver updates, what does anyone expect?). It also doesn't mention that mythical FPS-tanking DRM anywhere. For that to be proved, you would need to have a good CPU tank in framerate even on lower settings, proving the DRM is indeed holding it back and, not, you know, trying to play a cutting edge game on max before drivers and multi-card support.
