wow. I dunno if it's just the fact I do mostly low poly stuff, but I can't even recall any renders of mine that have taken over 10 minutes, and that was with a fairly filled out city environment, and about 5 or 6 vehicles on screen at once, and modeled out distance fog. That was with my old demo reel. Now that I've gotten better techniques, and my stuff is more optimized. I haven't had a render that's taken over 4 minutes, and that's because of some awful and stupid architecture of something I needed to optimize very badly. My average render times are just 40 seconds to 1.5 minutes. I think I'd go crazy trying to render a scene that takes an hour per frame
