Bonjour 

I am a long time Poser user and i used also Daz Studio from the beginning(now version 3 advanced edition 64 bits with many plugins)¸ 

I have installed Daz Studio 4 32 bits without problem and so far i liked it 

My principal complaint about version 3 was the libraries browser Hate it because many times i must locate manually the contents i want ,especially when i have used Poser files (yes all directories was indicated in preferences) 
BUT in DAZStudio 4 no problem like this using old ds scenes, pzz Poser scene,load prop lights poses etc from differents Poser runtimes All were working. I like it 

New interface: i am ok with it no problem using it 

Genesis people ok for now even it is limited in this free version 

Rendering :enough fast and comparable to Poser according to me 
I hope that Reality plugin will be adapted to this new version (joined a rendered image reduced for Poser imported file) 

Plugins : auto it seems very good but i prefer to wait and see if it will be included in advanced edition 
Hope dynamic clothing plugin will also be adapted and working good (in DazStudio 3 32 bits many times i was unable to reload a scene with a dyn cloth inside without error) 

Overall i am happy with this new version and plan to use it more than the old one
