It may be an interesting tell to disable the iterator macro and see what performance gains you achieve.
In regards to Steven Watkins comment, a powerful GPU is like a bandaid on a severed limb, the limb being vital QC patches which have regressed in performance do to extremely poor conceptualization, and new ones that never worked correctly to begin with, and are currently *more *broken than they were in the GM ( Open CL, Mesh Warps, Mesh Lines, etc.) What would be great is if they could be immediately regressed in an update (especially the iterator), but I think it's more likely to not be so immediate. That said, I have not found many situations where there are not workarounds in 10.6.x (although they are sometimes less obvious, the same visual result can be achieved many ways).
