Ah, I see where you're coming from now. Well, from the perspective of practical use the overhead is undeniably minimal (not annoying, in other words). But from a benchmarking perspective, with such small sample times, you'd need to at least attempt to measure the overhead and subtract it (if it were significant enough to do so) in order to get a more accurate benchmark. One from which the results might safely be used to extrapolate to other hardware. Personally I would really appreciate seeing a slightly longer test for that reason - as I said, 30 seconds to 1 minute per frame. It need not even be as many frames. I think as long as each machine has a chance to render 5 frames, it's probably a good test. So that's 50 frames, or less than an hour of rendering. Up to you, but that's my humble request. Thanks for listening, and for sharing your results with us. :) - Oshyan
