Like someone said before it also greatly depends on the complexity of the objects in your screen. If you have a shape with about 1000-10000verts (depending on importance of shape) you might want to multires that down. Try to shy away from greatly complex shapes. It also depends on what materials your are using with RayTrace, are you using the materials from 3ds's Raytrace 1 and Raytrace 2 folder? If so are you using glass? Their glass takes a long, long, long time to render it looks nice but its not worth it. I created my own glass texture which looks almost just as well but renders in about 1/20th of the time. I once had a 320 x 320 chessboard take about 45 mins to render, with just normal color then raytrace for reflections.
