Re: Tile by tile Rendering

Reading this, I am not sure if everyone is talking about the same sort of tiling...
It sounds to me as if the luxcore-tiling uses dynamic sampling conditions for each tile?
As far as I am aware, cycles just splits the rendering into segments, but otherwise renders the same. The (quite significant) performance differences found are being explained by different overhead, memory and cache usages. Read e.g. here, here, here or here. There are also reports of the GPU-behaviour being different with 2.8 (here), maybe in conjuction with the new CPU+GPU feature and the opposite behaviour of the two regarding tile size?
