Have you used a render farm ? You're right that rendering on a few cores is CPU bound. But you've moved the goalposts by 100,000,000 orders of magnitude. We have this comic on the wall with "programmer|compiling" replaced with "animator|rendering" http://xkcd.com/303/ And there's a standing order that you can't have sex unless you're rendering. >I'm not sure why I'm wasting time writing about this, it's obvious anyway. > > Yeah, that must be why everyone is rendering Imax movies in a few seconds. We can all imagine a place where computation is instant and we just say "computer! run Sherlock Holmes on the Holodeck from where we left off, but this time give it a Wild West theme".
