Hi Chris!
I can’t commit to help because I have other ongoing projects and I dont have my DAZ enabled computer until night, but
what you need to take care of
The PCs are usually powerfull and you may not have many performance problems as if you
deploy to Ipods for example, I have no experience about Web player performance
So you can test it first as is to see how good or bad the performance is
If it is not very good : (that depends of all the other stuff you are rendering in your app and your target FPS)
The DAZ models usually have lots of materials groups and the more material groups the more Unity draw calls, the less draw calls the better, so you can group the material groups until get 1 or 2 or depending of the different material effects you want, that can be done with DAZ studio
After that you will need decimate it until get something below 10k polygons or less depending of you game standards, you can do it with DAz decimator that will cost about 70
Then you need to create an Atlas Texture and decide the textures count and the texture size
Summary, low poly count, low number of material groups, 1 or 2 textures attlased
You may find that on Unity the clothing is not getting animated, because they are different meshes ( the character and the clothing) so you may need to export them in separate files and animate them at the same time or manage that on unity code
You can find on google some tutorials to do that
Where are you creating the animation? using Daz? or other tool?
Well as you see, there are some considerations to build your workflow for the first time and they will require test to find the appropiate balance of performance and good visuals
