Geometry load time into Octane is roughly proportional to the number of polys. So if you have 1 blade of grass and 1 tree and instance them, it will be very quick. The more (non-instanced) grass and tree polys you add, to longer the load time will be. How long (for Forest Pack) I don't know.
VRAM is more tested by textures than geometry - you can generally load a /lot/ of geometry onto a card.Will I have scene size limitations on my 4gb GTX 680?
That depends on the amount of geometry in the scene and how zoomed in you are (ie. distance shots seem to render a lot quicker than close-ups). I think people looking for 'real time' rendering would be using multiple video cards.Can I really expect 'real time' rendering?
