I have a question, what is the benefit of Cuda 3.0 over 2.0? Some examples what you can't do in cuda 2.0 that you can do in 3.0 will be great.

you'll read this in the release notes of beta2.

Awesome job with the physical sun and sky system guys!
I cant wait

How much GPU memory does a 7million poly model actually take btw?
I imagine it must pretty much max out any of the current cards.

So if a person have GTX 260 with 1792 (or better with more memory) can get some decent renders with a LOTS of polygons - 14+ millions.
What about instancing, are they gonna improve that number ?

Example : GTX 260 896MB ram, I have building set up approximately 1,5 millions polygons, and I add greenery, all greenery pieces (trees. grass. flowers, etc.) will take like 5 million more, so we are on the threshold of 900 MB, but if I scatter instances lets say equivalent to 15 million more polygons what will happens then? We will still need only 900MB to render or ?

with instances you can go as high as you want.
but they won't be supported yet in beta2.
