Quote - carrara has GC, and one of the reasons daz bought carrara was to get the rendering engine AFAIK.  however, users should be warned that caustics, GI, and some of those other items are still gonna slow it to a crawl, hence default users will skip them, just as they skip the cpu-intensive features of poser, even unto such basic operations as shadow-casting.

GI,caustic will render long.

but casting shadows? in 2009? we rae talking here about renders under 1 hour. only shadows is even under 30 minutes.  i dont think poser users dont use shadows because it takes to long to render. whats this 1999? they just dont want them. and maybe i would understand if they would use 15 or 20 raytraced shadows. but the default shadows? 
sorry but no.
