Savage_dragon, you seem to have an outdated computer and internet connection. :-) The dual cores entered the market for home use in 2005. Also, in the hard drives of modern computers with 500GB or more, a 450MB file is nothing (it's less than 0.1% of the total drive). In a normal 32Mb internet connection, these 450MB take about 2 minutes to download.

Regarding the logo, please note that it's not a watermark. It's a simple logo on the bottom right corner of the render. You can very easily crop it out in postwork. Just set your camera position in Vue in a way that the logo will appear in an area that is not interesting to you and then in post just crop it out. It's very easy.

For example, this image was rendered in Pioneer. It's one of the scenes that comes in the package. I just changed the camera position slightly, rendered and in post cropped the logo out.
