Nice image, Dust, she's looks nice and rounded and I like the tones!

As for your mobile GPU with 3GB VRAM, bloody hell, I totally messed-up when I built my system.  Don't get me wrong, I love my system but I actually built it for Octane yet still made a lot of mistakes.  At the time, I thought that getting two 1GB GTX460's would give me 2GB VRAM for Octane.  Sadly not, although I do get the speed of them both added together, Octane will only access the VRAM of one card.

Even importing a single, textured figure sucks-up VRAM pretty quick.

I do like Octane though, excellent renderer, I just wish it had anamorphic rendering so that we get proper stretched bokeh.  You'd think that from any physically based renderer we would have control over the geometry of the virtual glass (the lens), but we don't.  I asked about it and it did trigger enthusiasm, but whether it will actually come to Octane, I have no idea.
