@owei: Tnx a lot!!
Unfortunately, in some scenes, because of the lack of vram, some textures have been resized, so you have the loss of quality.
I currently use a GTX 580 1.5GB.
With the next WS, i will add another with 3Gb.
As for Octane, I am very optimistic about this engeene. I believe a lot in Octane, although it is very young, the team is doing a hard work to deliver a quality product, and each new release offers more small and new innovations that elevate its quality and always help the workflow.
There are still many things like the ability to create pass (ex: shadows, z-depth, multi uv for a single mesh, mask ...) or displacement .. But as the team tries to listen to users to improve the sw ... And this is a good thing.
I chose Octane after having tested many others sw ..
With Octane I have found a quality / time truly impressive. Almost all the images you see are created in double (some of them three times) the current size, and 1h / 1h 30min I had ready a clean image.
Obviously, the scenes where there is very glossy, transparency, IES files, it is normal cooking time will increase, but the new release with many new agevolazioi the calculation have been included to speed up the work.
Tnx again for the gallery.
@Nizar. Ciaaauuuu Belloooooo!!! ;) Tnx Man!!!!!
@gustavoeb:
When you purchase the license of Octane, you have access to many topics in the forum, including one dedicated to the plug for the various 3D apps.
At the beginning is not easy to enter in a new way of working, but after taking the hand is a wonderful thing.
I have a card GT220 - 1 Gb for video and GTX580 for rendering. Therefore, when calculating the render, I can WITHOUT ANY PROBLEMS, continue to devote to other work on XSI, or do post-production or whatever. With Mr. if I make a calculation, I just have to take so many many coffee ..

Also released today was the new plugin for XSI to export octane. Small preview:
