Hi all, lots of good input here.
One thing that confuses me: I was assuming that rendering in Nuke (not in background mode) would only affect one CPU - especially when rendering a quicktime movie file. But when I render a file, all my CPUs give full throttle. At least that is what my CPU-Meters tell me. Does Nuke render multi-threaded by default?
