[Update: If it helps rescue me, I found a page about the difference between rendering TS1 and TS3 in their respective times:

It turns out the original Toy Story took an hour per frame to render, whereas Toy Story 3 can render in real-time (or 24fps, at least.) Given that's probably on a server farm, my claim is still hyperbole, unless you expect cloud processing to be mainstream on all devices by then ;-)]
