Is this really comparable? It's still CPU based, isn't it? Besides 3D PDF, which I didn't know existed until now and I still don't understand the reason for its existence - what does it have going for it? My main attraction (I bought a license) to Octane is the rendering speed. Once I get my hands on one of the new Nvidia cards (4xx series), stuff will fly. Physically accurate almost realtime rendering? Hell yeah! (says he, who used to wait overnight to have a cube rendered on his 8MHz Amiga)
