I am new into zbrush and I would like to have a clarification from you fellows. Usually how many levels of subdivisions you use when you sculpt in zbrush? Or what should be the poly count to make a fine detailed model in zbrush? In my case my system is hanging after it reaches around 5-6 levels of subdivisions. (approximately 2 million polygons) Is it enough to make good sculpting? I think my systems configuration is not so bad. Hope somebody can help me on this..
