NURBS and GFX cards

 From:  ELF
Hey there, I just have a quick question.

When programs like MoI use the graphics cards for the viewports,
is the videocards processing NURBS surfaces, or is it somewhere converted to a polymesh?
What I mean is, do modern videocards support NURBS surfaces,
or does MoI just do a better job at delivering a poly representation, than for example Solidworks or Solid Edge?
