The longest I've had the first pass render at is about 1hr. I've found that each pass takes around 2X as long as the one before when working with Super setting, and there are 5 passes (6 with standard, but they're quicker). So if your 1st pass is, say, 4 hrs, you're looking at a render time of 4+8+16+32+64=124hrs = 5+ days. If it takes a day for the first pass, you might as well stop it as Bryce 9 will be out by the time it's done. Also, Rayraz, I'd disagree with the "all premium settings are slow" bit. It's mainly the rays / pixel that slows down the render as far as settings go, so a Premium-16, no matter what extras you have (i.e. soft shadow, ambience) will almost always be faster than a Super-32. Trouble is, the lower Premiums aren't as good at the same rays/pixel as the lower Supers. And if you want to use extras like DOF, you need to use 32 rays/pixel at least, preferably 64+, which drags the render time down. There was a thread about a week ago which went into all the do's & don'ts of how to get faster renders.
