Paolo,

Thanks very much for your reply & info.

I'll watch those videos and look over the info on your site some more & think about it.

But I'm cringing at the thought of having to remove DS 4.0 from my comp which does work and has no compatibility problems & replacing it with 4.5 in order to use Reality 2.5. A lot of people have reported problems with DS 4.5.16. I know that my current version is stable.

So what are the advantages of Reality 2.5 compared to 2.0? Besides faster rendering times.
