I know it's hard to make "TRUE" raytracing fast, but the people at Corel could also make a few 'not true' features in the render settings. That way you can choose between true reflections and 'not true' reflections. The same goes for DOF, Area shadows etc. And they could also include motion blurr. Having no motion blurr in bryce sucks. As for C4D The radiosity render in C4D is faster than the not radiosity render in bryce. (unless you make your scene very hard on radiosity.) And there's a free version. Plus you can buy the ART version if you don't have to animate.
