I’m rendering a scene with POV-Ray at 12000×5333 pixels, and in 11 hours 13 minutes it is 3% complete. Rough calculation gives 15 days to completion. The scene is filled with mirrors and lights, and uses every level of trace recursion I give it, currently set at 20 levels. (It involves the camera being inside a mirrored box, so that you can theoretically see to infinity in the reflections. The "barbershop mirrors" effect, but without your own head in the way.) I don’t want to wait two weeks, but I don’t want to sacrifice any part of the render quality…
