V3 is usable in P5 if you copy the !DAZ folders to the Libraries folder in your P5 Runtime. I did that, leaving everything else in my Pro-Pack install which is linked, and now morph injections take no time at all. All head injection takes about 3 minutes, and all body injection takes about 1.5 minutes. FBM injections are almost instant. May be worth doing if you want V3 in P5.
