Well it's realtime atm hehe, sitting at around 280k atm. I can easily render that in near realtime. (21.4fps) I'm speaking of the Utility where you can set max. Unforntunently it only goes up to 1,000,000 but that's alright.
You can also check your polycount under file/summary info/
But be warned Nurbs generate much more polys on rendertime than what is shown in the max tools (poly counter and so on..). And max unfortunately has a memory
problem that keeps most renderers to render more than 3-4 million polys of non-instanced geometry (those "I can
render 5 billion poly" news you might remember were all
using instances). I said most renderers because Brazil
is the only integrated renderer wich can render more.. through internal compression. I think the barrier is at around 8 million. 2,5 Million polys in your viewport might easily generate 10 million on rendertime. But you have detailed control about the tesselation of the viewport and render model in the "Surface Approximation" Rollout.
Personally I
