Cheers, I was clicking on the Draw Settings by mistake, and there was no options under Advanced for that part.

Got it, so now I'll have to have a look at all those interactivity settings so that I can get it to behave like Octane (I hope).  In Octane, when you rotate the scene, it breaks-up into larger pixels to make it nice and fluid to rotate even while it renders, so I'm hoping some of these settings will do that as well.  It's not as fluid as Octane at the moment cause there's a pause and then it shows the full render, whereas Octane was rendering all the time, even while I rotated the scene.  Like I said though, it's probably down to the settings, and wow, it looks a lot more sophisticated than Octane so far, I'm not sure I've seen half these settings before.

First impressions are very promising indeed!
