The opengl is bad w/ shadows especially. Check the log.txt in daz root to see if it says anything(not sure if it logs everything)also check windows application error logs.I would make sure you have latest daz too. Think it is 1.01. Rendering in daz w/ opengl is not a good idea. 3delight is nice, but it is slower. Tons of memory may make a difference tho.

No need to think outside the box....
    Just make it invisible.
