What would cause my Iray Renders to be minimal poly to the point where I can see the faces on a character's head,  while a card render looks perfectly smooth?

He's a Genesis import. Other exports look fine, even in the same scene, but this one seems to have vastly fewer faces. I have to subdivide to get him smooth, but even that isn't 100%. But he's high resolution real time and when I press F10 for a card render. I re-imported him and he looks the same. This suddenly started happening last week.
