Exactly, with the move to RIS, they're in pure path-tracing now, and they're still behind Arnold generally from a performance perspective. Displacement and subd performance is still very impressive (compared to Arnold), but motion blur (especially deformation for curves and triangles) has a noticeable overhead now.
