Jim, <<How much of an improvement in speed do you think might be realized if I add another 16MB to make 32 MB?>> This depends on the situation. If the mesh file fits into memory and no VMM is needed for the space subdivison, then more RAM will show minor improvements as only the space subdivison might be slightly better. With your special situation (143k faces) you will experience a significant increase in rendering speed with 32MB RAM, as the whole space subdivison data is now on your hard disk during rendering. In a highly reflective scene as yours this leads to a considerable amount of disk accesses. It is hard to say how much the speed increase is as it depends also on your hardware, etc.. I would estimate something like four times. Regards, Stefan
