Scarab, it is why you are having problems. A second injection figure -V3 or M3 - will not function properly. This was noted fairly early with V3 and DAZ has directions on their site about it. Rob talked about here early on. It is not as likely that two V3 figures will be used in a scene as it is that a V3 and a M3 will be used, so the problem has been not their problem by many up to now. It is like watching a train wreck = those who say they use a V3 figure with all morphs injected. While the body is not much different from V2 in size. The head is a whole 'nother universe. V3 with just the expression morphs - morphs that you need for every character - is 20,000,000 V2 with all stock DAZ morphs is 22,000,000 and V2 is a stress on many systems V3 with expressions and all body morphs - is 44,000,000 V3 with every morph - is 121,000,000 You can use a spawned charater (one morph/group) and set an expression, remove all morphs, save the charater, use IPB on it to get an injection pose for the expression, open the character again, inject just the expression morphs needed for the render and have a figure that is 6-8,000,000 - which is about as lean as you can get V3 (or M3). If your system is groaning, draging, nor freezing during a render - or you just want it to run as fast as possible, these steps many be worth the effort.
