I don't think the issue that Digitalis reported is necessarily the same thing. It's rare but I have seen genuinely "hung" renders before. The problem of long post-completion compute times is still unclear to me, i.e. whether it happens in regular circumstances or whether it's essentially confined to people over-stretching their system resources. I definitely want to find out if it's a TG2 issue though as I agree that it seems overly long for a post-render stage, regardless of the complexity of the render. If primary rendering is complete, I would think that all remaining work must solely be on resulting image buffers, which should be equivalent regardless of scene complexity (I think), and would be influenced only by render resolution and AA level. Having seen extremely high resolution (but simple) images go through the "completion" phase fairly quickly, it's hard to believe this should be normal, expected behavior. At the least, as Jo says, it should give more feedback to the user during that process.
