Know this is a old thread; ...but before you spend too much money on a new graphic card consider this – daz is known for dropping out of gpu and using the cpu. Just check out their forums, people don’t like that they spend a certain amount of money on a gpu and daz ends up using the cpu. And yes it is explained how if your scene is too big / does not fit in the gpu memory daz will use the cpu instead.

But here is the thing you can make a computer do what you want [not you reading this, but programmers] so the people at daz should recode the program to look for gpu drops and figure a way to feed the gpu smaller bits of the scene so it[the gpu] will not throw up. You know bits and bytes (see what I didn’t do there)
